Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a closed metal wire band cartridge for a closed metal forming and driving machine.

Conventionally, various devices have been devised for driving the closure, but in such devices, it is necessary to form the closure in advance. Therefore, a closed metal forming/driving machine has been proposed in which a closing metal wire band connected with closed metal wire is supplied to a forming driving device, a closing metal band is formed from the closing metal wire by the forming driving device, and the closing metal is driven in. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a closed metal wire band cartridge for a closed metal forming/driving machine that can reliably supply a closed metal wire to the forming/driving device of such a closed metal forming/driving machine.

In order to achieve this objective, in the present invention,
A closing pin is formed from a closing metal wire by a forming/driving device attached to a fixed member, and the closing metal is inserted into the forming/driving device of a closing metal forming/driving machine that drives the closing metal through an opening provided in the fixing member. The cartridge for supplying the wire band includes a housing that accommodates the closed wire band, a feed gutter connected to the outlet of the housing and whose feeding surface is flush with the lower surface of the opening, and a tip end of the feed gutter. a protrusion provided in the feed gutter and inserted into the opening, and an upper presser provided in the feed gutter, parallel to the feed surface, and protruding from the opening toward the forming and driving device, When the closing metal wire at the head of the band protrudes from the opening toward the forming and driving device, upward movement of the closing metal wire band is restricted by the upper presser.

FIGS. 1 to 4 are diagrams showing a closure molding and driving machine to which a closure wire belt cartridge according to the present invention is to be installed. As shown in the figure, the closure molding and driving machine 10 has one pedestal 20 attached to one closure head 30. As shown, the closure head 30 consists of a base 32 and an upright forward section 34. Its base 32 has an upright portion 2 extending upwardly from the base 20 at its rear end.
welded or otherwise securely attached to 2. This method of attaching the closure head 30 is shown by way of example only, and other methods of attaching the closure head 30 in fixed relationship with the pedestal 20 may be used. A front frame 40 is attached to its closure head 30 by a hold-down spring 50 for vertical movement in relation to the closure head.
Each end of the presser spring 50 is bent inward and has a leg 52 projecting inward,
Each leg 52 passes through a hole 54 on the opposite side of the front frame 40. Its respective leg 52 projects slightly toward each other a sufficient length to engage behind the rearward end 36 of the forward portion 34 of the closure head 30. Two protrusions 38 extending laterally on both sides of the closure head 30 fit into two U-shaped notches on both sides of the front frame 40. The four spacer protrusions 33 that are integrally formed with the front part 34 of the closure head 30 and extend forward are respectively positioned against the inner surface 46 of the front frame 40 and the front part 34 of the closure head 30. 34 so as to maintain a certain distance therebetween.

An elongated rectangular opening 44 is located in the center of the front frame 40, which receives the protrusion 62 of the forming block 60. The presser spring 50 has a generally V-shaped portion 56 bent downward;
6 presses against the outer surface of the molding block 60 and holds the molding block 60 in that position by spring force. In the gap between the closure head 30 and the front frame 40 created by the spacer projection 33, there is a former 70 and a driver 80 for forming a closure from a short piece of wire. be. The former 70 is placed against the inner surface of the front frame 40 and is located between two vertically extending slide rails 48 extending inwardly from the front frame 40 toward the closure head 30. . The two slide rails 48 can be stamped or otherwise formed from the same material as the front frame 40. The molding machine 70 usually has an inverted U-shape, and has two legs 7 extending downward.
2, the legs 72 of which are typically thicker than the top 74 of the former 70. The outer surface 76 of the leg 72 abuts the adjacent opposing surface 47 of the slide rail 48. Former 70 is narrowed at its upper end at central member 74, thereby creating two laterally projecting upwardly directed shoulders 78. The central member 74 is the former 7
It has a protrusion piece 75 cut out from a piece of material 0 and bent so as to extend rearward through an elongated opening in the driver.

Referring to FIG. 5, the driving tool 80 has two side pushers 84 separated from the driving blade 86 by two notches. This pusher 84 is slightly bent along a line 89 to extend forward and contact the inner surface 46 of the front frame 40. Both ends 85 of the pusher 84 are thus normally adapted to engage respective two upwardly facing shoulders 78 of the former 70. The outer portions of the two ends 85 are adapted to engage beveled cam surfaces 49 of the slide rail 48, with the cam surfaces 49 facing the respective outer portions of the ends 85.

Each of the two legs 72 of the former 70 has a respective recess 79 immediately below its two upwardly facing shoulders 78. each leg 7
2 also have respective grooves 77 along their inwardly facing ends, each groove 77 together forming a passage to facilitate shaping and driving the closure. Both outer ends 87 of driving blade 86
has a convex shape and is adapted to fit into the concave cross section of the passage forming the groove 77.

In addition to the four spacer protrusions 33, the closure head 3
The front part 34 of 0 has two coupling guide protrusions 35 protruding forward located on both sides of the driver 80,
This helps guide the driver 80 during its vertical movements. These parts are
Separated from the front section 34, which is not shown, is shown in FIGS. 5 and 6. It will be seen that the opposite outer ends 83 of the driver 80 slide into engagement with the inner surfaces of each of the two guide projections 35.

Extending rearwardly from the inner surface 46 of the front frame 40 are two control projections 43 that control the upward movement of the former as it returns to its original position. The upper end 81 of the former 70 is adapted to engage with the upper end 81 of the former 70. The two control projections 43 also lightly contact the front surface of the driver 80 so that the driver 80 does not budge during operation.

The document closer is constructed to accept a cartridge 90 having a housing 92, only a portion of which is shown (see FIG. 9). Inside the housing 92 is a closing wire 200.
are attached to each other to form a band-like shape, and a closed metal wire band 94 wound into a roll is accommodated therein, and a feed gutter 96 is connected to the outlet of the housing 92 . As shown in FIGS. 1 and 4, the feed trough 96 has four laterally projecting lateral projections that engage the lower surface of the inner projection 37 that projects inwardly from the base 32 of the closure head 30. It has a protrusion 98. This interlocking of the lateral projections 98 and the internal projections 37 ensures proper anastomosis between the outlet 102 of the feed trough 96 and the opening 100 in the anterior portion 34 of the closure head 30. Although not shown, the housing 92 and closure head 30 are coupled together by a suitable coupling method.

A feed pawl plate 104 is attached to the inside of the front portion 34, and the feed pawl plate 104 has two protrusions 106 projecting laterally, each of which corresponds to the two holes in the front portion 34. 108 (see FIGS. 2 and 9).
This feed claw plate 104 has two holding members 110, one on each side. The feed spring 112 made of spring steel has two holes 114 in the feed spring 112 and two holding members 110 on the feed pawl plate 104.
Two corresponding holes 1 near the bottom of each
Two rivets 11 passing through 18 respectively
6 is attached to the feed claw plate 104.
Between the two holding members 110, there is a driving claw 120 extending downward slightly forward of the holding members 110.
In the assembled state shown in FIG. 9, the protrusion piece 75 extending rearward of the former member 70 is in contact with the drive claw 120,
4 and feed spring 112 to feed the closing wire 200 as described below. Feed spring 1
There are two claws 121 at the tip of 12, which are in contact with the closing wire 200 of the closing wire band 94, as shown in FIG. The reverse feed control plate 122 is loosely attached to the feed gutter 96.
This reverse feed control plate 122 is held in that position by two protrusions 124 almost by their weight, and the two holding claws 126 are closed when the gold wire band 94
It rests on the closed gold wire 200. A rear end 128 of the reverse feed control plate 122 is in contact with a portion of the housing 92 to prevent the closing wire 200 from moving backward toward the cartridge 90.

The upper end 130 of the driving tool 80 is connected to the driving grip 13.
2, and a return spring 134 is mounted between the drive grip 132 and a rearwardly extending flange 138 which is integral with the front section 34. Return spring 134 applies upward pressure on both handle 132 and upper end 130 of driver 80 in a direction opposite to that indicated by arrow 140 in FIG.

The base 20 has one anvil 21 attached to its upper surface, and the anvil 21 has two bending grooves 23 corresponding to the driving blades 86.

At the beginning of the cycle of operation, return spring 1
34 is in the most fully extended state, and the grip is 1.
As shown in FIG. 9, numeral 32 is located at the uppermost position like the driver 80. The leading closing wire 200 is located in the groove 64 in the protrusion 62 of the forming block 60. The shaper 70 is at its uppermost level and its upper end 81 engages the lower surface of the control projection 43. The rearwardly extending protruding piece 75 of the former 70 is in close proximity to or in contact with the drive pawl 120 of the feed pawl plate 104 in the region shown as 131 in FIG. When the driving grip 132 is quickly operated downward, the closing wire 200 is formed and driven, while the feed spring 112 and the feeding pawl 121 are used to move the next closing wire 2.
00 is now ready to be fed into the groove 64. When the driving grip 132 is returned to its original position,
The parts are quickly returned to their original positions as described above and as shown in FIG. 9, while a new closing wire 200 is fed into the groove 64.

More specifically, its operation is as follows.

1 When the handle 132 is initially depressed, the driver 80 moves downward in the direction of arrow 140. Almost immediately after moving perhaps only 0.001 inch back and forth,
The lower ends 85 of both driver legs 84 of the driver 80 are connected to the two upwardly facing shoulders 7 of the former 70.
8 respectively. Driving tool 8
0 continues its movement further due to the force applied by grip 132, which in turn causes former 70 to move downward in the same manner.

As soon as the forming tool 70 begins to move downward, the protruding piece 75 begins to move rearwardly along the diagonal cam surface of the drive pawl 120 and
0 around its rotation axis 108 by a spring 112
Start moving backwards while resisting.

2. Through the leg 84 of the driver 80, the force exerted thereon by the driver 80 causes the former 70 to begin to move downwardly. The ends come into contact with both ends of the closing wire 200 held in the groove 64 of the forming block 60.

3 The forming device 70 is driven by the driving tool 80
Further downward movement of the closure wire 200 begins to separate the opposing ends of the closure wire 200 from the band 94 of the closure wire 200 to which they were otherwise joined together by adhesive or tape. At the same time, both legs 72 of the former 70 begin to bend the opposite ends of the closing wire 200 downward.

4 Formers 70 are attached to both ends of the closed wire 200.
The force applied through the legs 72 is resisted by the pressure applied by the forming block 60 and the front frame 40 as well as the spring 50. Therefore, both ends of the closing wire 200 are smoothly and continuously bent downward by the downward movement of the legs 72 of the former. While this movement is being performed, the bent leg of the closure
It is fitted into the groove 77 of the leg portion 72 of the former 70 . Immediately after the closure is formed into its U-shape, the curved portion of the forming device 70 or its terminal is
Upper surface 63 of protrusion 62 of forming block 60
I came into contact with this. As the former continues to move further downwards due to the force applied thereto by the driver 80, it now moves against the former forming block 6.
Push 0 downward in the same way. Because the molding block 60 is fitted into the opening 44 of the front frame 40, the front frame 40
It is moved downward with 0. While this movement is being performed, both ends 52 of the presser spring 50
moves downwardly along the rear end 36 of the closure head 30. However, with this configuration, the resistance exerted by the presser spring 50 on downward movement is not significant, and it is sufficient to hold the forming block 60 and the front frame 40 in their respective upper positions while forming the closure. may or may not be sufficient. This depends, to a large extent, on the strength of the closure wire 200 and its rigidity. It depends, in part, on how firmly the closure wire 200 is connected to the next successive closure wire 200 in the band 94. Therefore, both ends of the closing wire 200 are bent by the force applied by the former legs 72 because this force is transmitted to the forming block 60 and the front frame 40 and placed on the anvil 21. It is unlikely that much, if anything, will occur before the closing member 300 and the front frame 40 are pushed down until they come into contact. Depending on the interaction of various frictional forces, this downward movement of forming block 60 and front frame 40 can occur even before the ends of closing wire 200 have actually yet been bent. Alternatively, since the frictional force increases when both ends of the closing wire fit into the grooves 77 formed in the holding leg portion 72, the closing wire 200
It may occur while both ends of the are being bent. Alternatively, the curvature 73 may not come into contact with the surface 63 of the molding block 60 until after the closure has been molded (as is usually the case).

At the rear, during the downward movement of the former 70,
The projection piece 75 passes along the cam surface 142 of the drive pawl 120 and over the bend 144 to the flat portion 136. One end protrusion piece 75
Once the plateau 136 is reached, no further rearward movement and movement that would bring the drive pawl 120 into the armed state occurs, but rather the armed state is maintained. This operation of preparing the drive pawl by the pressure of the protrusion piece 75 is achieved when the driving leg 84 of the driving tool 80 comes into contact with the two cams 49 at the upper end of the sliding groove 48, as will be explained below. You have to wake up before you can do that. If this actuation operation is such that the bottom end 85 of the leg 84 is connected to the two cams 49
If not completed by the time , there will not be sufficient pressure applied to former 70 by driver 80 to ensure readiness of drive pawl 120 as described. This rearward movement of the drive pawl 120 is transmitted to the feed pawl 121 which rests on the band 94 of the holding member 110 and the closure wire 200 located further to the rear. This amount of backward movement is extremely small because the thickness of one closed wire 200 is less than twice the thickness of the closed wire 200. This retracted position is maintained until the grip 132 is released from the applied force, as explained below. Drive claw 12
During this backward movement of 0, the reverse feed control plate 122 prevents the band 94 from retreating, and thus the feed pawl 121 grasps the other closing wire 200 at the rear of the previous position. ensure that

The distance from the bottom end of the curved part 73 to the leg part 72 is
, so that the front frame 40 and the bottom ends of the legs 72 come into contact with the closure 300, which is normally closed at about the same time. However, if there is an interaction of various frictional forces as described above, and the front frame 40 comes into contact with the closing object 300 before the former 70 completes its downward movement; Once the front end 40 contacts the object 300 to be closed, the former 70 continues its downward movement forming the closure wire 200 and the bottom end of the leg 72 also contacts the object 300 to be closed.
Slide down along both sides of the closure until you hit 00. Just before the ends of the legs 72 come into contact with the object to be closed 300, the bottom ends 85 of the driving tool legs 84 begin to move upwardly along the cam 49, causing the legs 84 to close their fold line 89.
moves backwards against the natural spring pressure created by the This disengages leg 84 from upwardly facing shoulder 78 and allows it to slide along surface 79 of leg 72 with some resistance. Since the thickness of the leg portion 72 in the area of the surface 79 is the same as the thickness of the sliding groove 48,
The driver leg 84 slides downwardly along the slide groove 48 while maintaining contact with the surface 79 of the former leg 72. In this way,
Former 70 completes the last small portion of its downward movement until it contacts closure 300.

6 Further downward movement of the driver 80 together with the bottom end 85 of the driver leg 84 causes the former leg 72 to remain in contact with the closing object 300 while the driver leg 84 remains in contact with the surface. 79 and moves downward along the passage or ridge 48. Until the point at which the driving tool 80 begins to move downward relative to the stationary former 70, the protruding piece 75 of the former 70 is at or relatively close to the bottom of the notch 82 of the driving tool 80. It is located in Now, the driving tool 80 moves downward, and the notch 82 moves downward in relation to the stopped projection piece 75. During this movement, the bottom end 180 of the driver 80 is inserted into the forming block 60.
the bevelled upper corner 66 of the molded block 60, thus pushing the molded block 60 outwardly in relation to the front frame 40 and against the central portion 5 of the hold-down spring 50.
Press down against the pressure in Step 6. This releases the previously formed closure from the forming block 60. However, both legs of the closing metal are still part of the former leg 7.
2 remains in the passageway 77 formed by.

7 As soon as the forming block 60 begins to move in an outward direction, the bottom end 180 of the driver 80 passes that point and strikes the head of the already formed closure, driving the formed closure downward through the object to be closed. is driven in, at which point it is bent in a known manner by means of the bending groove 23 in the anvil 21. During this final driving of the closing metal,
A passageway 77 guides the closure and drive tool 80.

8 At the point when this driving is completed, the front frame 40 and the former leg 72 are in their lowest positions and rest on the closed object, while the driving tool 80 is on the closed object that has already been driven. It's sitting on a golden head. When the force applied to actuation grip 132 is released, actuation spring 134 releases actuation grip 1.
32 upwardly in the direction opposite to that indicated by arrow 140. This upward movement of actuating handle 132 lifts driver 80 with it.

During the upward movement of the driving tool 80, the notch 82 therein also hits the projection piece 7 of the former 70.
move upward in relation to 5. When the bottom end of the notch 82 engages the protruding piece 75, the force applied by the actuating spring 134 causes the driving tool 80 to move further upwardly, thereby also pushing up the forming tool 70 with it. Driving tool 80
At some point in the upward movement of former 70, front frame 40 and forming block 60 begin to move upward as well. The particular point at which front frame 40 and forming block 60 begin to move upwardly is determined by the interaction of various frictional forces. In addition, as well as the frictional anastomosis between the driver leg 84 and the surface 79 of the former leg 72, the driver 80 and the passageway 7
By frictional anastomosis with 7, the former 70
Although the projection piece 75 is still located at the upper end of the notch 82, it will begin to move upward at the same time as the driving tool 80 moves upward. It is not important in what order the driver 80, former 70, former block 60 and front frame 40 begin their upward movement, or whether they begin their upward movement simultaneously. In fact, because of the difference in frictional forces, some parts, such as the front frame 40 and the forming block 60, will temporarily stop moving just when they start moving upwards. The only important thing is that all parts are returned to their original positions and that all parts are designed to achieve this purpose as shown.
They have learned to adapt to each other.
For example, if the former 70 continues its upward movement together with the driving tool 80, it will eventually be stopped by a frictional force, or the upper end 81 of the former will be stopped by the control projection 4 in the front frame 40.
3, but in that case the front frame 40
If it has not already been returned to its original position by the hold-down spring 50, a further continued upward movement will also move the front frame 40 with it; in that latter case, the control projection 43 will The upward movement of the driver 80 causes upward movement of the notch 82 in relation to the prong 75 of the former 70. On the other hand, if the frictional force is such that it captures the upward movement of the former before the former reaches its uppermost peak, then the upward movement of the driver 80 is , the notch 82 is moved upward in relation to the protruding piece 75 until the bottom end of the notch 82 engages with the protruding piece 75 . At that time, the driving tool 8
The further upward movement of 0 also causes the shaper 70 to move upward.

9. At some point in the upward movement of the driver 80, the driver leg 72 passes from below to above the cam surface 49 at the upper end of the guide ridge or guideway 48; As soon as the former 70 is captured by the friction force or by the control projection 43, the driving tool 80 moves the former 70
As the notches 82 begin to move upwardly in relation to the lug 75 and the driver legs 84 pass upwardly over the shoulder 78, , front frame 40
along and correspondingly upwardly along the surface 79 of the former 70 until returning to their original position relative to the inner surface of the former. Because the driver 80 is spring steel, the driver leg 84 returns to its original position as shown in FIG. It will be seen that it is located at the top.

10 When the driving tool 80 reaches the projection piece 75 of the former 70 and presses the end 81 of the former 70 against the control projection 43 of the front frame 40, all of the upward movement of all the parts is finally completed. be stopped. Immediately before reaching this point, the protruding piece 75 moves along the slope 142 of the drive pawl 120 to the flat part 131;
supplies the unformed closing wire 200 to the groove 64 in the forming block 60, and shortly before the driver 80 passes through the opening 44 in the front frame 40 from below upwards, the forming block 60 is inserted into the groove 64. It has returned to its normal position.

The closing wire 200 is inserted into the groove 6 of the forming block 60.
4, the end of the closing wire 200 is in the vicinity of the sliding groove 48 to restrict its movement and to position it properly within the groove 64 (see FIG. 5).
The closing wire 200 is supplied to the forming block 60 so that the first closing wire 200 is supplied to the forming device member 70.
When the wire 200 is first contacted and separated from the strip 94, the wire 200 is closed to the forming block 60 during that portion of the downward driving motion.
It is similar to when it is not pressed. This sequence of operations prevents movement of the closing wire 200 at this point in the driving movement from going in an undesired direction.

FIGS. 14, 15 and 16 show other closure forming and driving machines to which a closure wire belt cartridge according to the invention is to be installed.
Most of the parts of the closed die forming driving machine shown in Figures 14, 15 and 16 are identical to most of all the parts of the closed die forming driving machine shown in Figures 1 through 13. , and similar parts are provided with the same reference numerals. The biggest difference between the closure molding and driving machine 400 and the machine 10 is that the machine 400 has a single locking mechanism that is normally located where the operating handle 132 is located in the machine 10 shown in FIGS. 1-13. It is activated by an electric solenoid 402. The solenoid 402 is connected to a rigid frame or closure head 30.
by means of a fixing band 404 or the like,
It is attached to hold the solenoid 402 in a fixed position. The driver 80 has an armature 406 at its upper end 130 that extends through a solenoid 402 . Therefore, the solenoid 402 is activated by the switch SW1.
When the armature 406 is actuated, the armature 406 is driven downward, and the driving tool 130 is driven down to form and drive a closure. Spring 134 is housed within armature 406 to keep the design compact.

The solenoid 402 is connected by conductors 408 to a suitable electrical circuit C (one of which is the actuation switch SW1). The circuit C is then connected by conductors 409 (one of which
There is an on/off switch SW2) connected to a power supply S, for example an AC power supply. Circuit C is of a well-known conventional design and therefore will not be described in detail here. One suitable circuit is

Also, both ends 410 of the presser spring 50 pass through two oval holes 412 in the front frame 40 and are tightly inserted into two holes 44 on both sides of the vertical member 34 of the closure head or frame 30. They are different in that they are completely absorbed in it. Oval hole 412 in the front frame 40 of the machine shown in FIGS. 14-16
differs from the hole 54 in the front frame 40 for the machine shown in FIGS. 1-13 only in that it is located closer to the entire surface of the front frame 40.
In this position, the ends 410 of the hold-down spring 50, instead of engaging after the end 36 of the vertical member 34 of the closure head 30 as seen in the machine 10,
Two holes 414 in the vertical members of the closure head 30
They are stuck in each. With this array,
Both ends 410 of the presser spring 50 are shown in FIGS.
No longer a vertical member 3 as seen in the machine shown in fig.
It will be seen that there is no sliding up and down along the rear end 36 of 4. Thus, unlike the machines shown in FIGS. 1-13, the front frame 40 of the electrically operated machine 400 does not move downwardly toward the closed object 300 during operation. Rather, the front frame 4
0 remains stationary in relation to the closure head 30 during all normal operating phases of the machine 400.

It will be recalled that during operation of the machine shown in FIGS. 1-13, the legs 72 of the former 70 cooperate with the forming block 60 to form a closure from the unformed closure wire 200. Dew. Additionally, after forming the closure, the curved portion or end 73 of the former 70 extending between the legs 72 is lowered onto the forming block 60, as shown in FIG. Then, the molded block 60 and the front frame 40 are
It will be recalled that the front frame 40 is pushed down until it reaches the thing 300 to be closed.
In the machine 400, the front frame 40 is held stationary against downward movement;
Former 70 must be modified. Thus, as shown in FIG. 16, the only difference between the former 470 shown therein and the former 70 shown in FIGS. 2, 5, and 6 is that 4
The curved portion or end portion 473 of the former 70
It is located at a higher place than the end 73 of. That is, the distance from the bottom end of both legs 72 in FIG. It is greater than the distance. Thus, during operation of the device, the legs 472 form a closure from the closure wire 200 and the legs 472 form the closure 300 without the ends 473 reaching or touching the forming block 60. Continue the movement until contact is made.

The two pushers 84 of the driving tool and the forming tool 70
When the closure molding step is completed, the former 70, together with the legs 72, continues downwardly toward the closed closure 300 of the formed closure by frictional anastomosis with the end 85. It is shaped and balanced to carry and guide.

Except as stated in the previous paragraph, the first
The operation procedure of the machine shown in Fig. 4 to Fig. 16 is as follows.
The operating procedure of the machine shown in FIGS. 1 through 13 is the same in all essential respects.

In each of the above machines, the presser spring 50

2, so the front frame 40
will move outwardly a small distance from the fixed closure head 30, which distance
4, 412 and the diameters of both ends 52, 410, respectively. This elliptical degree is such that the front frame 40 is directed outwardly from the closure head 30 to eliminate any unformed or unformed closure wire that would otherwise clog the device. It has been chosen to provide sufficient margin. Therefore, in order to fix the jammed condition of the machine,
It is only necessary to operate the machine rapidly and continuously until the jam condition returns to normal. By doing this, the presser spring 50 is attached to the front frame 40.
will be pushed back into place in relation to the fixed closure head 30.

FIGS. 17 to 22 are views showing a closed metal forming and driving machine equipped with a closed metal wire cartridge related to the housing. As shown in the figure, the feed spring 112 is attached to the holding member 1 by two rivets 116.
10. The holding member 110 is the shaft 50
It swings about a shaft 502 by a support portion rotatably attached to the shaft 502. Since the drive pawl 120 is integrally constructed with the holding member 110, the two feed pawls 121 are driven by the feed spring 112.

The housing 92 that accommodates the closed wire band 94 has a feed gutter 5 connected to the outlet of the housing 92.
03 is attached, and the feed gutter 503 is connected to the board 5.
04, it has a base side wall 506 and two side protrusions attached to the outside of the substrate 504, and the upper surface of the substrate 504, that is, the feeding surface, is flush with the lower surface of the opening 100. The rear ends 511 of the two guide pieces hold down the reverse feed control plate. The front frame 40 has eight spacer protrusions 512 and 51 each having two spacer protrusions in one set.
3, 514 and 516. Cart cartridge 9
0 is held in its operating position by spring 517.

The cartridge 90 is then seated in its lower position within the closure head 30 by means of a spring 517, also shown in dotted lines, as shown in dotted lines in FIG. Next, the cartridge 9
0 is the feed gutter 50 as shown in FIG.
The protrusion 508 provided at the tip of the opening 10
0 and is pushed to the left against the spring 112 until it reaches the front frame 40. The width of the opening 100 is considerably longer than the length of the closing wire 200. The protrusion 508 is located between the spacer protrusions 514 and 516, and a portion of the upper presser 509 provided in the feed gutter 503 parallel to the feed surface is also attached to the closure head 3.
0 through the opening 100, the head 30 and the front frame 40
It protrudes into the gap between. As the band 94 is advanced into the forming block 60, the leading closing wire 200 contacts the two spacer protrusions 514 and is properly positioned within the forming block 60.

To explain FIG. 21, when the first closing wire 200 is fed into the forming block 60,
It can be seen that both ends thereof extend under the two upper pressers 509, respectively. Upper presser foot 50
9, when a part of the leading closing wire 200 protrudes into the gap between the closing device head 30 and the front frame 40, the driving blade 86 and the forming device 70 operate upward to close the closing wire. Closing wire 2 at the beginning of the wire band 94
It functions to prevent 00 from being pushed upward. In this way, the protrusion 508, the upper presser 5
09 and aperture 100 cooperate therebetween to guide and hold the cartridge 90 in place, and the closing wire 200 is bent during the movement back over the driving blade 86 and former 70. It can be seen that this prevents the wire from being bent, distorted, or coming off the closed wire band 94.

Two upper pressers 509 located inside the opening 100
In this case, the first closing wire 200 is the cartridge 90.
It forms part of the edge that defines the exit exit from the molding block 60 into the molding block 60.

As explained above, in the closure wire belt cartridge for the closure molding and driving machine according to the present invention, the closure wire can be reliably supplied to the forming driving device of the closure molding and driving machine. Thus, the effects of the present invention are significant.
