Description

  The present invention relates to an anti-adhesion treatment method and an apparatus for applying an anti-adhesion treatment to a strip-like member made of an unvulcanized rubber material used for manufacturing a long member such as a hose or an electric wire or a pneumatic tire for an automobile. It is.

In general, this type of belt-shaped member anti-tack treatment apparatus includes a hollow sealed container containing a powdery anti-tack agent and an anti-tack agent deposited on the lower end side of the sealed container. A blowing device that blows up the air, a separation device that separates the anti-blocking agent blown up by the blowing device from the air and discharges only the air to the outside, and a circulation that sends the anti-blocking agent separated by the separating device to the lower end side of the sealed container An apparatus and a supply port and a discharge port for supplying and discharging a band-shaped member made of an unvulcanized rubber material in a closed container, and preventing the adhesion of the band-shaped member entering the sealed container from the supply port by the blowing device There is known one in which an anti-adhesive agent is allowed to adhere to the entire surface of the belt-shaped member in a short time through the inside of the agent (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 10-109061

  By the way, in the anti-tacking treatment device for the band-shaped member, while the anti-blocking agent is blown up and the band-shaped member passes through the blown-up anti-blocking agent, a space for blowing up the anti-blocking agent is required, There is a problem that the apparatus is enlarged by the amount of the space.

  In addition, since a separation device for separating the blown anti-blocking agent from the air and a circulation device for sending the anti-blocking agent separated by the separation device to the lower end side of the sealed container are required, the separation device and the circulation are required. There was also a problem that the size of the device increased by the amount of the device.

  Furthermore, there is a problem that the anti-blocking agent is not pressed against the band-shaped member only by passing the band-shaped member through the blown-up anti-blocking agent, and the anti-blocking agent is difficult to adhere to the surface of the band-shaped member.

  The present invention has been made in view of the above problems, and the object of the present invention is to allow the anti-adhesive agent to adhere to the entire surface of the belt-shaped member made of an unvulcanized rubber material in a short time, Moreover, it is an object of the present invention to provide an anti-adhesion treatment method and apparatus capable of reducing the size of the apparatus.

In order to achieve the above object, the present invention provides a method for preventing adhesion of a band-shaped member comprising adhering a powdery anti-blocking agent to a band-shaped member made of an unvulcanized rubber material. A scraper formed so as to extend in the axial direction of the drive roller in a state where the belt-like member is wound around the outer peripheral surface of the drive roller disposed in the container so that the belt-like member passes through the outer peripheral surface of the drive roller. The belt-shaped member is conveyed in the longitudinal direction by rotating the driving roller and the anti-adhesive agent is continuously adhered to the belt-shaped member.

As a result, the drive roller is rotated in a state where the belt-like member is wound around the outer peripheral surface of the drive roller arranged in the container so that the belt-like member passes through the anti-adhesive agent accumulated in the container. Since the belt-like member is driven and transported in the longitudinal direction, the belt-like member smoothly moves in the longitudinal direction in the accumulated anti-sticking agent, and the belt-like member passes through the anti-sticking agent. The anti-sticking agent adheres over the entire circumference. At this time, the anti-adhesive agent is pressed against the surface of the belt-shaped member by its own weight. Further, since the scraper contacts the outer peripheral surface of the drive roller, the anti-adhesive agent does not adhere to the outer peripheral surface of the drive roller.

Further, the present invention provides a strip-like member anti-adhesive treatment apparatus for adhering a powdery anti-blocking agent to a strip-like member made of an unvulcanized rubber material. the adhesive in inhibitors are deposited in the container together with the belt-shaped member is wound on the outer peripheral surface as the belt-shaped member to pass through, and a driving roller for conveying a belt-shaped member wound around the longitudinal direction, the drive roller And a scraper that is formed so as to extend in the axial direction and abuts against the outer peripheral surface of the drive roller .

As a result, the belt-like member is wound around the outer peripheral surface of the drive roller so that the belt-like member passes through the anti-adhesive agent accumulated in the container, and the drive roller places the wound belt-like member in its longitudinal direction. Since it is conveyed, the belt-like member moves smoothly in the longitudinal direction in the deposited anti-blocking agent. Moreover, when passing through the inside of the anti-blocking agent, the anti-blocking agent adheres to the belt-like member over the entire circumference. Further, since the scraper contacts the outer peripheral surface of the drive roller, the anti-adhesive agent does not adhere to the outer peripheral surface of the drive roller.

According to the present invention, the belt-like member can be smoothly moved in the longitudinal direction in the deposited anti-blocking agent, and the belt-like member is prevented from sticking all around when passing through the anti-sticking agent. At this time, the anti-blocking agent is pressed against the surface of the band-shaped member by its own weight, so that the anti-blocking agent is reliably adhered to the entire surface of the band-shaped member made of unvulcanized rubber material in a short time. be able to. Further, since the anti-blocking agent can be attached to the belt-like member without requiring the anti-blocking agent to be blown up, it is not necessary to provide a space for blowing up the anti-blocking agent or a device for collecting the blown-up anti-blocking agent. This is extremely advantageous in reducing the size of the apparatus. Furthermore, since the anti-adhesive agent does not adhere to the outer peripheral surface of the drive roller, the outer diameter of the drive roller does not increase due to the adhesion of the anti-adhesive agent, and the conveyance speed of the belt-like member can be kept constant at all times. It is. Further, since the anti-blocking agent fixed in a lump on the drive roller does not adhere to the belt-like member, it is advantageous in making the amount of the anti-sticking agent attached to the belt-like member uniform.

FIG. 1 is a side view of a belt-shaped member forming apparatus, FIG. 2 is a side cross-sectional view of an adhesion preventing treatment apparatus, and FIG. 3 is a perspective view of a suction member. FIG. 4 is a perspective view of a main part of the belt-shaped member forming apparatus, and FIGS.

  The anti-tack treatment apparatus 40 of this embodiment is provided in a belt-shaped member forming apparatus. This belt-shaped member forming apparatus is rolled by an extruder 10, a rolling roller 20 that rolls a belt-shaped member BM1 made of an unvulcanized rubber material extruded from the extruder 10 to a predetermined thickness, and the rolling roller 20. The strip-shaped member BM2 is cut at a plurality of locations in the width direction to form a plurality of strip-shaped members BM3 each having a predetermined width dimension, and an adhesive is attached to each strip-shaped member BM3 cut by the cutting device 30. Anti-adhesion processing device 40 to be carried, a transport device 50 for transporting each strip-like member BM3 that has passed through the anti-stick treatment device 40 in its longitudinal direction, and a guide device for guiding each strip-like member BM3 sent out from the transport device 50 60, a plurality of upper surface opening containers 70 each formed to open an upper surface, and a container transport device 80 for transporting each upper surface opening container 70. .

  The extruder 10 has a known mechanism for extruding an unvulcanized rubber material from a die having a predetermined shape. When the unvulcanized rubber material is extruded from the extruder 10, the unvulcanized rubber material is The band-shaped member BM1 has a width dimension and a thickness dimension.

  The rolling roller 20 has a pair of rollers 21 and has a well-known configuration capable of adjusting the rotation speed and gap of each roller 21. When the belt-like member BM1 extruded from the extruder 10 passes between the rollers 21, the belt-like member BM1 is rolled to a predetermined thickness and becomes a belt-like member BM2.

  The cutting device 30 includes a transport roller 31 around which the belt-shaped member BM2 is wound and transports the belt-shaped member BM2 in the longitudinal direction, and a plurality of cutters 32 that are in contact with the outer peripheral surface of the transport roller 31. The transport roller 31 is rotatable by an electric motor (not shown). While the belt-like member BM2 is wound around the roller 31 and the belt-like member BM2 is conveyed in the longitudinal direction, the cutters 32 are arranged at a plurality of positions in the width direction of the belt-like member BM2, so that the belt-like member BM2 has a width. A plurality of strip-like members BM3 each having a predetermined width are cut at a plurality of locations in the direction. That is, each strip member BM3 is continuously formed by the extruder 10, the rolling roller 20, and the cutting device 30.

  The anti-tack treatment apparatus 40 includes a container 41 for storing a well-known anti-sticking agent PW in powder form, a drive roller 42 provided in the container 41, an impeller 43 provided in the container 41, and a container 41. A plurality of air discharge members 44 as air supply means provided inside, a plurality of scrapers 45 provided inside the container 41, and a pair of suction members 46 provided outside the container 41 are provided. Each suction member 46 can be provided in the container 41.

  The container 41 includes a main body 41a having an upper surface opened and a lid 41b capable of closing the opening on the upper surface of the main body 41a. The anti-sticking agent PW accommodated in the container 41 is deposited in the main body 41a. The lid 41b is provided with an inlet 41c for feeding each strip member BM3 into the container 41 and an outlet 41d for feeding each strip member BM3 out of the container 41. The lid 41b is moved up and down by a lifting device (not shown). When the lid 41b is raised by the lifting device, the opening on the upper surface of the main body 41a is opened, and when the lid 41b is lowered by the lifting device, the main body 41a. The opening on the upper surface of the is closed.

  The drive roller 42 is rotated by an electric motor (not shown). Each strip member BM3 fed into the container 41 from the inlet 41c is wound from below on the outer peripheral surface of the drive roller 42 via the first auxiliary roller 42a, and each strip member BM3 that has passed through the drive roller 42 is 2 It is sent out of the container 41 from the outlet 41d via the auxiliary roller 42b. That is, each strip member BM3 passes through the deposited anti-blocking agent PW, and the anti-blocking agent PW adheres to each strip member BM3 over the entire circumference when passing through the anti-blocking agent PW. At this time, the anti-blocking agent PW is pressed against the surface of each band-shaped member BM3 by its own weight, and the anti-blocking agent PW reliably adheres to the surface of each band-shaped member BM3. A scraper 42c is in contact with the outer peripheral surface of the drive roller 42 from above. The scraper 42c is formed so as to extend in the axial direction of the drive roller 42, is in radial contact with the outer peripheral surface of the drive roller 42, and is adhered to the outer peripheral surface of the drive roller 42 as a lump. Is supposed to be removed. Further, a contact member 42d is provided to contact each belt-like member BM3 that has passed through the drive roller 42 from the thickness direction. Here, the drive roller 42 comes into contact with one surface in the thickness direction of each strip member BM3, and the contact member 42 comes into contact with the other surface in the thickness direction of each strip member BM3. Yes. The abutting member 42d is formed so as to extend in the width direction of each belt-like member BM3, and is disposed in the deposited anti-blocking agent PW. As a result, the anti-adhesive agent PW is pressed against one surface in the thickness direction of each strip member BM3 by the drive roller 42, and the anti-adhesive agent PW is pressed against the other surface in the thickness direction of each strip member BM3 by the contact member 42d. Therefore, the anti-blocking agent PW can be more reliably adhered to both surfaces in the thickness direction of each strip member BM3.

  The impeller 43 is rotated by an electric motor (not shown). The impeller 43 includes a shaft member 43a formed so as to extend in the axial direction of the drive roller 42, and a plurality of blade members 43b provided on the outer peripheral surface of the shaft member 43a. As the impeller 43 rotates, the anti-sticking agent PW accumulated in the main body 41a of the container 41 is agitated.

  Each air discharge member 44 is attached to the side surface of the main body 41 a in the container 41. Each air discharge member 44 has a substantially rectangular parallelepiped shape, and most of the air discharge member 44 other than the attachment portion with the main body 41a is a discharge port 44a for discharging air. The discharge port 44a is covered with a cloth-like member or a net-like member made of a metal material, a fiber material, a plastic material, or the like. The air discharge member 44 is connected to an air supply device (not shown) so that air supplied from the air supply device is discharged from the discharge port 44a. Further, in a state where the anti-adhesive agent PW is accommodated in the main body 41a of the container 41, each air discharge member 44 is arranged in the accumulated anti-adhesive agent PW. Here, since the discharge port 44 a of each air discharge member 44 is covered with a cloth-like member or a net-like member, the anti-adhesive agent PW hardly enters the air discharge member 44. In addition, since the discharge port 44a of each air discharge member 44 is covered with a cloth-like member or a net-like member, the air supplied from the air supply device is prevented from adhering via the cloth-like member or the net-like member of the discharge port 44a. It is supplied silently in the PW. When the air is gently supplied into the anti-blocking agent PW, the supplied air moves between the respective powder particles in the anti-blocking agent PW so as not to blow up the anti-blocking agent PW, and the accumulated adhesive. Released from the upper surface of the inhibitor PW. For this reason, when each air discharge member 44 is not provided, each particle of the anti-blocking agent PW is in close contact, and the anti-blocking agent PW tends to harden, but the air is gently blown so as not to blow up the anti-blocking agent PW. When supplied, since the supplied air passes between each particle of the anti-blocking agent PW, the deposited anti-blocking agent PW does not harden.

  Each scraper 45 comes into contact with each strip member BM3 that has passed through the driving roller 42 in the thickness direction. Each scraper 45 is formed so as to extend in the width direction of each strip-like member BM3. A part of each scraper 45 abuts on one surface in the thickness direction of each strip-like member BM3, and the other scrapers 45 The belt-shaped member BM3 comes into contact with the other surface in the thickness direction.

  Each suction member 46 is formed of a cylindrical member whose both ends are closed, and is formed so as to extend in the width direction of each belt-like member BM3, and a suction hole 46a is formed at a predetermined position in the circumferential direction of the outer peripheral surface (FIG. 3). reference). The suction hole 46 a is a long hole formed so as to extend in the axial direction of the suction member 46. The outer peripheral surface of one suction member 46 among the suction members 46 abuts on one surface in the thickness direction of each strip-like member BM3 fed from the outlet 41d of the container 41, and the other suction member 46 among the suction members 46. Is in contact with the other surface in the thickness direction of each strip member BM3 fed from the outlet 41d. Each suction member 46 is provided such that the position in the rotation direction can be arbitrarily set around the rotation axis A extending in the axial direction. That is, by changing the position of each suction member 46 in the rotation direction, the distance between the suction hole 46a provided on the outer peripheral surface of each suction member 46 and each strip member BM3 is changed. Each suction member 46 is connected to an air suction device (not shown), and can suck air from the suction hole 46a.

  The transport device 50 is formed of, for example, a well-known belt conveyor, and each strip member BM3 that has passed through the anti-adhesion processing device 40 is placed thereon, and each strip member BM3 is transported in the longitudinal direction.

  The guide device 60 includes a guide member 61 and a moving mechanism 62 that reciprocates the guide member 61 in the transport direction (hereinafter referred to as a member transport direction) of each band-shaped member BM3 by the transport device 50, for example. The guide member 61 includes a pair of guide plates 61a provided so as to face each other in the member transport direction, and a pair of fixing plates 61b that fix the guide plates 61a. Each guide plate 61a is formed in a flat plate shape, and is arranged so that the interval between the guide plates 61a gradually decreases from the top to the bottom. The moving mechanism 62 supports the guide member 61 and reciprocates the guide member 61 by a known mechanism such as a motor or a ball screw. In addition, the guide member 61 is disposed below the front end of the transport device 50 so that each strip member BM3 sent out from the transport device 50 passes between the guide plates 61a of the guide member 61.

  The top opening container 70 includes a flat bottom plate 71 and a pair of side plates 72 extending upward from both ends of the bottom plate 71 in the member conveying direction.

  The container transport device 80 is formed of, for example, a well-known roller conveyor or belt conveyor, and includes a first transport path 81 provided so as to extend in the member transport direction, and a second transport provided so as to extend in the width direction of each strip member BM3. Path 82. A plurality of upper opening containers 70 are placed on the container transfer device 80, and each upper opening container 70 is transferred from the second transfer path 82 side to the first transfer path 81 side. Further, any one of the upper surface opening containers 70 on the first transport path 81 is arranged below the guide device 60.

  In the band-shaped member forming apparatus configured as described above, when the band-shaped member is formed, first, each band-shaped member BM3 is continuously formed by the extruder 10, the rolling roller 20, and the cutting device 30, and the anti-adhesion processing apparatus. By 40, an anti-adhesive agent is continuously adhered to each strip member BM3.

  Here, in the sticking prevention processing device 40, each belt-like member BM3 is fed into the container 41 from the inlet 41c, and each belt-like member BM3 is wound around the drive roller 42 from below through the first auxiliary roller 42a and driven. Each belt-like member BM3 that has passed the roller 42 is sent out of the container 41 from the outlet 41d through the second auxiliary roller 42b. Further, each strip member BM3 is wound around the outer peripheral surface of the drive roller 42 arranged in the container 41 so that each strip member BM3 passes through the anti-adhesive agent PW accumulated in the container 41. . Further, by rotating the drive roller 42, each strip member BM3 is moved in the longitudinal direction. That is, each band-like member PW3 passes through the deposited anti-blocking agent PW in the longitudinal direction, and when passing through the inside of the anti-blocking agent PW, the anti-sticking agent adheres to each band-like member PW over the entire circumference.

  On the other hand, each suction member 46 is in contact with both surfaces in the thickness direction of each strip member BM3 fed out of the container 41 from the outlet 41d. Each of the suction members 46 sucks air from the suction holes 46a provided on the outer peripheral surface, and sucks the anti-adhesive agent PW that is unnecessarily attached to the belt-like members BM3.

  Each belt-like member BM3 to which the anti-sticking agent PW is adhered by the anti-sticking treatment device 40 is continuously transported by the transport device 50, and each belt-like member BM3 sent out from the transport device 50 is sent to each guide member 61 of the guide device 60. Passes between the guide plates 61a.

  In addition, since any one upper surface open container 70 of the upper surface open containers 70 on the container transport device 80 is disposed below the guide member 61 of the guide device 60, each of the upper surface open containers 70 that have passed between the guide plates 61a. The belt-like member BM3 is accommodated in the upper surface opening container 70. In this state, the moving mechanism 62 of the guide device 60 reciprocates the guide member 61. In other words, the guide members 61 reciprocate in the member transport direction while the strip members BM3 are continuously passing between the guide plates 61a of the guide member 61. It is accommodated in a folded shape (see FIG. 1).

  When a predetermined amount of each band-shaped member BM3 is accommodated in the upper surface opening container 70 that accommodates each band-shaped member BM3, the reciprocating motion of the guide member 61 by the moving mechanism 62 is stopped, and the container conveying device 80 performs the first operation. The upper surface opening container 70 on the conveyance path 81 is moved in the member conveyance direction (see FIG. 5). As described above, the fact that each band-like member BM3 is accommodated by a predetermined amount can be detected by the number of times of reciprocation of the guide member 61 or a known detection means such as an optical sensor. Next, the empty upper surface opening container 70 on the second conveyance path 82 is disposed below the guide member 61 of the guide device 60 by the container transport device 80, and the reciprocation of the guide member 61 is started after a predetermined time has elapsed (see FIG. 6). As a result, the strip members BM3 that have passed between the guide plates 61a of the guide member 61 are accommodated in a folded manner in the empty upper surface opening container 70, and a plurality of upper surfaces are cut without uselessly cutting the strip members BM3. It can be accommodated in the open container 70. For this reason, for example, when supplying each strip member BM3 to the hose manufacturing apparatus, unlike the case where the length of each strip member BM3 is finite, the connection work between the ends of each strip member BM3 can be omitted, This is extremely advantageous for improving production efficiency and quality.

  Thus, according to the present embodiment, each of the belts BM3 passes through the anti-sticking agent PW accumulated in the container 41 so that each belt member BM3 passes on the outer circumferential surface of the drive roller 42 disposed in the container 41. In the state where the belt-like member BM3 is wound, the drive roller 42 is rotationally driven to transport each belt-like member BM3 in the longitudinal direction, so that each belt-like member BM3 is deposited in the accumulated anti-sticking agent PW. Moves smoothly in the longitudinal direction. Moreover, when passing through the inside of the anti-blocking agent PW, the anti-blocking agent PW adheres to each strip member BM3 over the entire circumference. At this time, the anti-sticking agent PW is pressed against the surface of each band-like member PW by its own weight. For this reason, the antiblocking agent PW can be reliably adhered to the whole surface of each strip | belt-shaped member BM3 which consists of an unvulcanized rubber material in a short time. In addition, since the anti-blocking agent PW can be attached to each band-like member BM3 without requiring the anti-blocking agent PW to be blown up, a space for blowing up the anti-blocking agent PW and the anti-blocking agent PW that has been blown up are collected There is no need to provide a device, which is extremely advantageous for downsizing the device.

  Further, since each belt-like member BM3 moves smoothly in the longitudinal direction in the deposited anti-blocking agent PW, even when each belt-like member BM3 is thinly formed or made of a soft unvulcanized rubber material. The dimensional accuracy of each strip member BM3 can be ensured, which is extremely advantageous for improving quality.

  Further, since air is supplied so as not to blow up the anti-blocking agent PW into the anti-sticking agent PW accumulated in the container 41, when no air is supplied into the anti-blocking agent PW, the anti-blocking agent is used. Since the PW powder particles are in close contact with each other and the anti-sticking agent PW tends to harden, air passes between the powder particles of the anti-sticking agent PW and the deposited anti-sticking agent PW does not harden. Each strip member BM3 can be smoothly moved in the longitudinal direction in the deposited anti-blocking agent PW, which is extremely advantageous for ensuring the dimensional accuracy of each strip member BM3. Further, uneven adhesion of the anti-blocking agent PW due to the anti-sticking agent PW solidifying can be prevented, which is extremely advantageous in improving the quality of each strip member BM3.

  Further, since the impeller 43 is rotated in the anti-sticking agent PW accumulated in the container 41, it is possible to more effectively prevent the accumulated anti-sticking agent PW from solidifying.

  Further, each suction member 46 is brought into contact with both surfaces in the thickness direction of each strip member BM3 that has passed through the inside of the anti-blocking agent PW, and air is sucked from the suction holes 46a provided on the outer peripheral surfaces of the suction members 46, respectively. Thus, the anti-adhesive agent PW adhering unnecessarily to each band member BM3 can be removed, and the guide member 50 and the like can be removed by the anti-adhesive agent PW adhering to each band member BM3. The device will not get dirty. Further, it is advantageous for making the amount of the anti-blocking agent PW adhering to each band member BM3 uniform. Furthermore, since the suction member 46 is in contact with each strip member BM3 in the thickness direction, for example, when the anti-blocking agent PW that is agglomerated on the surface in the thickness direction of each strip member BM3, The blocky anti-blocking agent PW can be removed from each strip member PW, which is more advantageous in making the amount of the anti-blocking agent PW adhering to each strip member PW uniform.

  Further, since the scraper 42c formed so as to extend in the axial direction of the driving roller 42 is brought into contact with the outer peripheral surface of the driving roller 42, the anti-adhesive agent PW does not adhere to the outer peripheral surface of the driving roller 42. . For this reason, the outer diameter of the drive roller 42 does not increase due to the adhesion of the anti-blocking agent PW, and the conveyance speed of each band-like member BM3 can be kept constant. In addition, the anti-blocking agent PW adhered to the drive roller 42 as a lump does not adhere to each band member BM3, which is advantageous in making the amount of the anti-blocking agent PW adhering to each band member PW uniform. .

  Further, since each scraper 45 formed so as to extend in the width direction of each strip member BM3 is brought into contact with each strip member BM3 that has passed through the anti-blocking agent PW from the thickness direction, each strip member BM3. The amount of the anti-blocking agent PW adhering to can be made uniform.

  In the present embodiment, a plurality of scrapers 45 are provided. However, only one scraper 45 may be provided.

  In the present embodiment, the plurality of air discharge members 44 are provided. However, only one air discharge member 44 can be provided.

  In the present embodiment, a pair of suction members 46 is provided. However, only one suction member 46 may be provided.

  In the present embodiment, the suction member 46 is formed in a cylindrical shape, but the suction member 46 can be formed in a polygonal column shape or a plate shape.

  In the present embodiment, the suction member 46 is provided with one suction hole 46a, and the suction hole 46a is a long hole. On the other hand, a plurality of suction holes 46 a are provided on the outer peripheral surface of the suction member 46, the suction holes 46 a are round holes or long holes, and the suction holes 46 a are provided so as to be aligned in the axial direction of the suction member 46. It is also possible.

  In this embodiment, the discharge port 44a of each air discharge member 44 is covered with a cloth-like member or a net-like member so that air is gently supplied into the anti-adhesive agent PW. On the other hand, by providing a plurality of small discharge ports in each air discharge member 44, it is also possible to supply air gently into the anti-blocking agent PW. Furthermore, it is also possible to form the discharge port with a well-known porous member and supply air gently into the anti-blocking agent PW.

  Further, in the present embodiment, a plurality of strip members BM3 are continuously formed by the extruder 10, the rolling roller 20, and the cutting device 30, and the antiblocking agent PW is continuously applied to each strip member BM3 by the antistick treatment device 40. Although what was made to adhere was shown, one strip | belt-shaped member was continuously shape | molded by the extruder 10, the rolling roller 20, and the cutting device 30, and the anti-blocking agent PW was apply | coated to the strip | belt-shaped member by the adhesion prevention processing apparatus 40. It is also possible to make it adhere.

  In addition, in this embodiment, although each strip | belt-shaped member BM3 to which adhesion prevention agent PW was attached showed what was accommodated in the upper surface opening container 70 which opened the upper surface in the shape of folding, the adhesion prevention agent PW was made to adhere. Each strip member BM3 can be wound around the winding shaft, and the strip member BM3 can be stored by other methods.

  In the present embodiment, each suction member 46 is brought into contact with both surfaces in the thickness direction of each strip member BM3 that has passed through the inside of the anti-blocking agent PW, and suction holes provided on the outer peripheral surfaces of the suction members 46, respectively. What sucked air from 46a was shown. On the other hand, as shown in FIG. 7, a brush 100 and a dust collection nozzle 110 can be provided instead of each suction member 46. In this case, the brush 100 formed in a columnar shape is brought into contact with both surfaces in the thickness direction of each band-shaped member BM3 that has passed through the anti-blocking agent PW, and the adhesive adhered to each brush 100 by each dust collecting nozzle 110. The inhibitor PW is sucked. The rotation speed and pressing force of each brush 100 can be arbitrarily set. Thereby, by changing the rotation speed and pressing force of each brush 100, it is prevented that the anti-adhesive agent PW adheres unnecessarily to each strip member BM3, and the amount of the anti-stick agent PW attached to each strip member BM3. It is also possible to adjust.
