Description

Description: FIELD OF THE INVENTION The present invention relates to a method and an apparatus for producing a bonded sheet-like product for a sachet having one or more compartments for containing an article to be packaged, and more detailed. The present invention relates to a method and apparatus for producing a porous bag in which particles are contained and formed by adhesion, and storing a granular packaged object in the bag by utilizing fluid pressure.

[Prior art and problems]

There are numerous methods and devices for making various bags, sachets, and sealed packages that have been improved over the years. For example, a method and apparatus for making a tea bag filled with black tea, etc. is disclosed in U.S. Pat. No. 4,262,473 (Patentee Arthur A. Brooke, 1981).
April 21, 2010). In this Brook's method, a porous web is made into a flat tube and tea leaves are continuously introduced into the tube. Usually, the flat tube containing the black tea is first moved horizontally, and the tube is sandwiched at a predetermined interval by using a bag sandwiching device, and the sandwiched bag and the tube are vertically moved. By this vertical movement, due to the action of gravity, the black tea in the tube moves downward, and the portions immediately below each part sandwiched in a linear shape of the tube become empty, so that using the heat welding device, The sachets, which are heat-sealed across the empty space and thus formed in a continuous manner, are cut into individual tea bags, ie a group of tea bags, using a cutting device.

U.S. Patent No. 3,498,019 (patentee JM rate (JMRai
t), dated March 3, 1970) also discloses a method and apparatus for making sealed packages. The patent for this sheet is to use a thermoplastic material for sealing packaging, in which case
The item to be packaged is placed on the upper surface of the sheet of thermoplastic material in a predetermined shape. After that, a thermoplastic second sheet is covered in parallel with the thermoplastic first sheet, and the two sheets are fusion-sealed by using a heated rotary cylinder having compartments. The movement of both the upper and lower sheets is synchronized with the rotation of the rotary cylinder. This is so that when the upper and lower sheets move under the rotary cylinder, the compartment of the surface of the rotary cylinder comes to the position of the tea placed on the lower sheet.

U.S. Pat.
No. 3,813,848 (disclosed by Andrea Romagnole, patentee, dated June 4, 1974, this method uses a rotating drum-type feeding device, the drum of which is recessed. Then, various products to be packaged are fed from the recesses by a predetermined amount to the upper surface of the moving web of the packaging material to be deposited.
Cover the deposited product with a second strip of packaging material,
Adhesive to the upper surface of the first packaging material. A similar batch meter is disclosed in U.S. Pat. No. 4,437,294 (patentee Andrea Lomagnoli, March 20, 1984).
U.S. Pat. No. 4,404,787 (patentee G. Hazelwood, dated September 20, 1983) also discloses a packaging device, which includes a rotary tea delivery device. This tea feeding device deposits a predetermined amount of black tea on the packaging material, covers it with another packaging material, and seals the upper and lower packaging materials so as to surround the pile of black tea piled up one by one. Then separate the tea bags one by one.

A method of making a tea bag with a wide bottom is described in U.S. Pat. No. 2,571,138 (patentee HO Irmsche
r), dated 16 October 1951). In this method, a porous sheet-like packaging material is folded in half, and its open parallel both sides are gripped with a pair of grippers to form the above-mentioned open bag, and the measured tea is measured as described above. Put it in the bag from the upper opening, then make a closed bag by sealing the upper opening and both sides extending in the transverse direction, and attach a handle made of a knob and a thread to this bag. Then, separate the above bags one by one.

In addition, a packaging tool that heat-seals the peripheral edge portion and further heat-seales non-linearly to form a predetermined section inside and fills this section with soap powder is disclosed in US Pat. No. 4,433,783 (patented by
RH Dickinson, February 28, 1984). In this packaging tool, a pair of panel-like packaging materials are used to sandwich powder soap from the front and back, and the powder soap is spread in layers between the pair of packaging materials.
To make this wrapping, the wrapping is heat-sealed along the periphery of the wrapping to create a compartment for the powder soap, and this compartment is heat-sealed multiple times to form a series of small compartments. This subdivision is to prevent the soap powder from moving during handling. In the Dickinson patent specification, it is described that the treatment for further heating and sealing the section in which the powder soap is put can be performed without any trouble even if the powder soap is present in the portion to be sealed.

A method and apparatus for manufacturing sanitary napkins and other sanitary products is disclosed in U.S. Pat. No. 2,073,329 (patentee CP Winter (C.
P. Wiuter), dated 9 March 1937), this method uses a rotating wheel, which has a meshed inlet which is connected to a suction device. Cotton fibers are accumulated in a predetermined pattern, and the accumulated fibers are stacked on a gauze moving along the lower edge of the rotating wheel, that is, the first rotating wheel. The gauze further travels to the second wheel, and as it rotates around the second wheel, the rough absorbent material is selectively added to the cotton fibers or patches loosely stacked on the gauze. The absorbent material is pressed against the gauze so as to have a predetermined shape, and is piled up to form a pad. This gauze and pad together are further processed in the next step.

Although many attempts have been made to date to improve the method for producing a packaging material having a compartment for containing a predetermined amount of the article to be packaged, as is clear in some of the above-mentioned patents, the thin layer adhesion as described above is performed. There is still a problem in producing high-speed, high-quality, and efficient packaging materials using an automatic device. For example, it is time-consuming, unreliable and difficult to increase the processing speed even if it is attempted to accurately and rapidly granulate a predetermined amount of a granular material by using a device and a method which have been industrially used recently.

[Object of the Invention]

 An object of the present invention is to solve the above problems.

Another object of the present invention is to form a sheet of packaging material comprising porous upper and lower webs, the perimeters of which are joined together and having a compartment for containing a predetermined amount of an article to be packaged in a predetermined shape. An object of the present invention is to provide a device and method that can be efficiently manufactured.

Still another object of the present invention is to maintain the surroundings of the sections of the web in a state where there is no article to be packaged in order to bond the upper and lower webs of the porous body, and further, to package the article to be packaged in a predetermined amount, An object of the present invention is to provide an apparatus and a method capable of more efficiently producing a porous bag containing a predetermined pattern.

Still another object of the present invention is a device having upper and lower webs, which can be more efficiently bonded around the perimeters of the webs to make a porous bag containing a certain amount of particulates. And to provide a method.

This method allows the perimeter of one or more pouches to be sealed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. However, this example is not intended to limit the invention thereby.

1 to 9, the same symbols represent the same members. 1 and 2 show details of a method and apparatus for joining the peripheries of the upper and lower webs to create a porous packaged product having one or more compartments therein. A predetermined amount, that is, a predetermined amount of the article to be packaged is placed in the compartment formed inside the sheet-shaped packaged product. In particular, FIG. 1 schematically illustrates a process 10 for continuously making a porous, adhesively-formed sheet-like packaged product 18. In this step 10, the upper web 16
And the lower web 15 is continuously supplied to the compartment forming section 50.
The partition forming section 50 is a mold core that further holds the mold.
51 and a rotary mold drum 52 outside the mold core, which comprises an inner portion 54 and an outer compartment forming surface 53.

The partition forming surface 53 has, in the figure, one or more object-to-be-packaged loading 55, and a cavity 56 inside the object-to-be-packaged loading 55. The cavity 56 is surrounded by a plate-like peripheral edge 57. It has a curved shape. The plurality of cavities 56, 56, ... Are shown in the shape of a rectangle, but the shapes of the cavities 56 and the terrace-shaped peripheral portion 57 are the above-mentioned sections, that is, the sections in which the article of the adhesive-formed sheet-like packaging material is put. It can be formed into any shape according to the shape of.
The passage 58 is connected to the package loading unit 55 to a vacuum device (not shown) to selectively depressurize the cavity 56, as will be described later. Although only one passage 58 is shown in the figure, the passage 58 is not limited to one and any number may be used to connect the article loading unit 55 to the vacuum device as needed. The plateau-shaped peripheral portion 57,
In the figure, there are one or more holes 57, 59, ... Penetrating this peripheral edge 57, and these holes 59 are connected to a pressurized fluid supply device and selectively guide the pressurized fluid to the plate-shaped peripheral edge 57. From at least a portion of it as described below. The pressurized fluid may be any suitable fluid, the preferred one being gas such as air.

The passage 58 extends into the molded mold core 51 in the figure, and the mold core 51 is provided with various passages and grooves connected to a vacuum device. With this structure, the air in the article-to-be-packaged loading section 55 is evacuated by a vacuum device. The method of removing the air may be arbitrary, and the method described here is only one preferable example. In the same way, holes 59 are used to create a series of grooved passages.
It connects to 61 and connects this passage 61 to one or more pressurized fluid supply devices. Such an internal passage 61 is also provided in the molded mold core 51. The passage 61 and the vacuum device are separately connected to the pressurized fluid supply device or the vacuum device when the mold drum 52 rotates around the mold core 51 during the manufacturing of the packaging material.

The partition forming surface 53 preferably has a structure that rotates around the fixed mold core 51. The partition forming surface 53 is machined, cast or molded from a hard material suitable for the purpose and then finished into a shape suitable for the above structure. As a material of the partition forming surface 53, for example, polyurethane, aluminum, hard rubber, various steel alloys, or the like may be used. The cavity 56 may vary widely in size. For example, in the case of making a substantially quadrangular compartment (as shown), the package loading section 55 is a quadrangle having sides of about 13 to 76 mm (about 0.5 to 3 inches) or more. The dimensions of the terraced rim 57 can be varied according to the application conditions, the dimensions of the entire section and the requirements for the terraced rim. For example, the package loading unit
If 55 is almost square, reduce the length of the terrace 57
13 to 76 mm wide with a width of about 3.17 mm (0.125 inch). The depth of cavity 56 is determined based on the specific requirements for the dimensions of the compartment. The total diameters of the mold core 51 and the partition forming surface 53 can be largely changed according to the required manufacturing speed, the size of each partition, the size of the entire sheet-shaped packaging material to be bonded and formed, and the like.

As already mentioned, the internal passages connecting the vacuum device and the pressurized fluid supply device can be of various constructions, such as pressurized chambers or similar industrially used passages.
Although the details will be described later, it is necessary that all of the passages can be connected to the object-to-be-packaged loading portion 55 and that the cavity can be selectively depressurized. Similarly, the holes 59 in the terraced perimeter 57 are selectively connected to a pressurized fluid supply to blow pressurized fluid (eg, air) from at least a portion of the terraced perimeter when needed. Must be installed so that it can be taken out. Also, while the apparatus and process according to the present invention are most preferably configured to rotate as previously described, the compartment forming surface 53 is generally flat to allow for attachment to a reciprocating device and manual operation. It can also be a face. In such a case, the compartment forming surface 53 can be stationary or portable as required. Further, the partition forming surface 53 is formed into a substantially cylindrical shape,
.. may be provided adjacent to each other, and the loading section 55 may be completely surrounded by the plate-like peripheral edge section 57 to be separated from the adjacent loading section 55. In addition, one piece of the article-to-be-packaged 55 is surrounded by a plate-like peripheral edge portion 57, and a porous packaging material having one compartment for containing a predetermined amount of the article-to-be-packaged is adhered by using the article-to-be-packaged loading portion 57. Although it can be formed, from the viewpoints of economy and efficiency, the partition forming surface has a substantially cylindrical structure, and a plurality of object-to-be-packaged parts 55 are provided around this cylindrical portion to provide a rotary continuous structure. It is preferable that the partition forming surface has a different pattern.

The process of FIG. 1 will be described in more detail. The first web 1 made of a porous material is supplied from an unwinding type material supply roller 21, and the tension of the first web 15 is widely used industrially. Maintained by a simple dancer-type tension controller. The tension control device shown in FIG. 1 is an example of this, and the tension control device includes tension adjusting rollers 22 to 24, and the continuous first web 15 moves toward the compartment forming device 50. Through a zigzag path. The first web 15 can be made of any of the widely used perforated materials in industry, such as paper, perforated thermoplastics, or cloth, but the web must be porous. It is desirable that the multi-directional strength is large and the tensile strength is strong so that the packaging material can be formed in the above-mentioned device without breaking. For various paper materials usable in the present invention, U.S. Pat. No. 4,638,907 (filing date 1984
Applicant William T. Bedenck, November 28, 2014
Bedenk) and Kendell L. Hard
in), the title of the invention is described in laminated laundry bags), which patent application is incorporated herein by reference.

The porous first web 15 contacts the upper surface of the compartment forming surface 53. Since one or more cavities 56 are formed in the compartment forming surface 53, it is preferable to deform the first web 15 so as to correspond to the contour of the compartment forming surface 53. In the embodiment shown in FIG. 1, the porous first web 15 is embossed by a male embossing roller 75. This embossing process is the above-mentioned first web 15
Is brought into contact with the partition forming surface 53. The embossing roller 75 is provided with a protrusion having a shape corresponding to the contour of the partition forming surface. Instead of this protrusion, the first web 15 is provided with the partition forming surface 53.
It is also possible to provide a simple soft rubber roller that can be forced into the cavity. The method for deforming the first web 15 is
It does not need to be limited to any particular method, and in some cases,
It is also possible to bring the first web into contact with the compartment-forming surface 53 and simply use the force of a vacuum to partially encase the first web in the cavity of the compartment-forming surface. It is also possible to contribute the weight of the article to be packed placed in the cavity of the compartment forming surface to the embossing work. In the figure, the porous first web is also shown.
The direction changing roller 25 is provided as a device for bringing the section 15 into contact with the partition forming surface 53, but this is an example, and any other device may be used.

Also, in order to deform the first web, a device (not shown) is used in conjunction with the web to fold the first web in the direction of the device and / or in the transverse direction of the device. Sometimes it's good. Such a device for forming pleats on the web is widely used industrially, and when the first web 15 is not easily deformed by other methods or when the first web 15 is easily broken or perforated. Is preferred.

When the compartment forming surface 53 is continuously rotated, for example, in the clockwise direction, the first web 15 is rotated under the article feeding device 84 as shown in FIG. The article P to be packaged is deposited on the upper surface of the first web. In this case, it is extremely preferable to connect the cavity 56 of the article-to-be-packaged loading 55 to a vacuum device before supplying the article to be packaged.
The object to be packaged P is put in a sheet-shaped packaging material to be formed by adhesion, and moves freely in accordance with free fall or air, that is, has fluidity and behaves like a liquid when the above-mentioned loading operation is performed. Can be shown (hereinafter, such a free-falling packaged object is referred to as a “flowable packaged object, for the sake of simplicity of description). The property that the object to be packaged can flow like a liquid or a fluid is important for exerting the advantages of the object to be packaged device in which the vacuum device and the pressurized fluid supply device of the present invention are combined. in this case,
The article to be packaged P is preferably fibrous, powdery or granular. Another advantage of the present invention is that particles that are easily "fixed", that is, particles that are easily attached, can be easily processed by using the above-mentioned unique vacuum device and pressurized fluid supply device for supplying an object to be packaged.

As shown in FIG. 1, the article P to be packaged is supplied from the hopper 80 to the compartment forming device 50. That is, the object to be packaged P is hopper
From 80 to the feeding device 84 via the weighing device or the conveying device 82. The transfer device 82 is configured by using an appropriate number of transfer devices that are easy to obtain, such as a vibration type conveyor and a conveyor belt. In the feeding device 84, the material P to be packaged is adjusted (for example, individual fibers or grains are loosened) by the transport device 82, and the material P to be packaged is deposited on the upper surface of the first web 15. Can flow almost like a fluid. The flowable article P is fed to the first web 15 via the feeding device 84.
Deposit on the upper surface of. For such loading, cavity 56 must be connected to the vacuum system and hole 59 must be connected to the pressurized fluid supply system. The porous first web
The reference numeral 15 acts as a collection filter for the object to be packaged when the object to be packaged having the fluidity is absorbed in the cavity 56 by the action of the vacuum. This package P forms a layer of substantially uniform thickness in the cavity 56 as best shown in FIG.

Passageway 58 must be sized to adequately draw in a quantity of air that is slightly greater than the total quantity of air expelled from holes 59. This relationship is important. The reason for this is that when the suction of the passage causes an inward force, this force pulls the first web 15 inward, and when the article to be packaged is deposited on the first web and the first web is adhesively formed. This is because the first web can be held on the partition forming surface 53. To explain this in more detail, the work of depositing the object to be packaged on the first web by suction of the air is performed under a slight reduced pressure to prevent scattering or loss of the object to be packaged into the air around the object. be able to. The fluid P to be packaged falls along with air onto the upper surface of the first web 15 like "rain" or mist at a predetermined speed via the conveying device 82 and the feeding device 84, and the vacuum device The object P to be packaged accompanying the air is sucked into the cavity 56, and the pressurized fluid (eg, pressurized air) blown out from the hole 59 expels the object to be packaged that moves with the air from the peripheral edge 57 of the terrace. . The absolute value itself of the pressure of the vacuum device and the fluid pressurizing device may be appropriately changed depending on the physical characteristics of the packaged object, the feeding amount, the rotation speed of the compartment forming surface 53, and other related factors. it can. What is important here is that the action of vacuum and gravity attracts the article P to be packaged to the first web 15, and the partition forming surface 53 of the article P to be packaged on the upper surface of the first web 15 and the rotation of the article P to be packaged. The object is to prevent the product P from moving due to the centrifugal force, and to sufficiently hold the article to be packaged P on the upper surface of the first web. The pressure of the pressurized fluid blown out from the plate-like peripheral portion 57 is larger than the action of gravity on the package P falling from the feeding device 84 onto the plate-like peripheral portion and the adhesive force of the package P. Must. For example, if the cavity is approximately square and one side is about 38 mm (1.5 inches) and the size of the package P is in the range of about 100 to 1000 microns, the diameter of the passage 58 is about 9.5 mm (about 3 mm). / 8 inch), and the pressure and vacuum pressure of the pressurized fluid is about 305 to 5 in the water column.
It has been found preferable to be within the range of 08 mm (about 12 to 20 inches).

In the continuous manufacturing apparatus shown in FIG.
Are continuously and uniformly fed by the feeding device 84, and are batched by the feeding device 84 in units of compartments, that is, in the form of pouches (for this purpose, for example, a feedback type monitoring device is used to package objects. Can also be controlled by a weight monitoring method). In addition, in the case where two or more parcels to be packed P are fed, the parcel P
Can be controlled so as to be synchronized with the rotation speed of the compartment forming surface 53 or the standard weight of the packaging machine 18 as a product.

Since the pressurized fluid is blown from the terrace-shaped peripheral portion 57, the article to be packaged P is uniformly deposited on the section forming surface 53 for each section. At this stage, it is not necessary to form a specific pattern so that the above-mentioned packaged object is accurately deposited on a specific portion, and it is not necessary to use a special method. Since the pressurized fluid is blown out from the hole 59, the plate-like peripheral edge portion 57 is continuously and automatically maintained in a state in which there is no object to be packaged. However, the width of the articles P to be accumulated in the article loading section 55 in the transverse direction of the manufacturing apparatus is narrower than the width of the cavity 56 in which the articles P to be accumulated P are accumulated in the transverse direction of the manufacturing apparatus. In such a case, it has been found that the pressurized fluid blown out from the holes 59 arranged in the transverse direction of the manufacturing apparatus in the plate-like peripheral edge portion 57 of the cavity is minimized, and it is possible to eliminate the pressurized fluid depending on the situation. However, in order to bring the plate-like peripheral edge portion 57 into a state in which there is almost no article to be packaged, that is, a clean state without precisely controlling the feeding of the article to be packaged, the pressurized fluid is directed toward the manufacturing apparatus and across the same. It is preferable to blow it out in the direction. The above plateau-shaped peripheral portion 57
The width of can be varied (as described above) according to the detailed dimensions of the individual compartment-forming surfaces, but in order to keep the plate-like edges clean during feeding of the package. It has been found that it is preferable to set the width of the plate-like peripheral portion 57 to 3.17 mm (0.125 inch) or more. In this way, if the width of the plate-like peripheral portion is minimized, the pressurized fluid that blows out creates a "tunnel" along the longitudinal direction of the plate-like peripheral portion 57. The peripheral portion 57 can be sufficiently kept in the above-mentioned clean state.

As described above, various kinds of items can be packaged by using the method and the device according to the present invention. For example, flowing tea, powdered coffee, powdered soap, fibrous cotton and paper, materials with excellent absorption capacity, and other materials that behave like fluids as described above. It can be P. When the density of the object to be packaged is low, the degree of vacuum is increased, and when the object to be packaged is loaded, the object to be packaged is strongly sucked and settled down so as to collide with the cavity 56. This is to remove the influence of centrifugal force generated by the rotation of the compartment forming surface and the fed packaged object. By a unique method for loading an object to be packaged, which is a combination of this vacuum device and a pressurized fluid supply device, a porous package which is adhesively formed in a sheet shape so as to have one or more compartments containing a predetermined amount of the object to be packaged. The material can be continuously manufactured at a higher speed than before.

In FIG. 4, the first web 15 is in contact with the partition forming surface 57 to form a cavity 56.
The cross-sectional view when it deform | transforms so that it may respond | correspond to the outline of FIG. FIG. 5 is a cross-sectional view showing a state in which an article to be packaged is loaded on the upper surface of the first web of the compartment forming surface of FIG. 4 shown in FIG. As shown in this figure, the article P to be packaged is attracted into the cavity 56 by suction of the vacuum device connected to the cavity 56 via the passage 58, while the pressurized fluid blown out from the hole 59 is fed into the cavity 56. The object is removed from the portion of the first web 15 overlying the plateau rim 57. However, as is clear from the figure, the object to be packaged P in the cavity 56 is slightly raised at the portion adjacent to the plate-like peripheral edge portion 57, and a ridge point is formed on the edge.
Form 90. Such ridges 90 normally do not interfere with the subsequent manufacturing steps, but the ridges 90 may be prior to the adhesive forming process, especially if the second web is flattened or untensed on the upper side. Is preferably low. First
As shown in the figure, after the article P to be packaged is deposited on the upper surface of the first web 15, the first web and the cavity containing the first web pass under the doctor mechanism 70. ,
Before the second web is adhered to the upper surface of the first web 15, it is flattened and lowered.

FIG. 6 shows a state after the ridge points 90 of the partition forming surface 53 of FIG. 5 are smoothed by the doctor mechanism. The doctor mechanism 70 may be any device capable of performing the required doctor action, such as a blade, brush, or air knife. It has been found that a fairly soft brush is suitable for this doctor mechanism. It is not necessary for this brush to contact the upper surface of the portion of the first web 15 which overlies the plate-like peripheral edge 57. To operate the doctor mechanism, the cavity 56 is connected to a vacuum device and pressurized air
It must be blown out from 59 and completed while the operation of putting the article to be packaged P in the cavity 56 as described above is being performed.

Regardless of the presence or absence of the doctor process, the partition forming surface 53 continues to rotate clockwise and the second web is supplied, and the second web is bonded to the upper surface of the first web 15 along the plate-like peripheral edge portion 57. To form one or more porous compartments with sealed perimeters. As shown, the upper or second web 16 is fed from a feed roll 31 and is a standard dancer type tension control device (rollers 32 through 32).
Move through 34). FIG. 1 shows an adhesive application device. This adhesive applying device includes an adhesive applying roller 41, a corresponding pressing roller 42, an adhesive supplying reservoir 44,
And an adhesive 43. The adhesive 43 may be applied in the same manner as pattern printing (as in a gravure-type adhesive applying device), but normally it is applied to the surface of the second web 16 and the surface to which this adhesive is applied is the lower side. To the upper surface of the first web 16. The upper second web 16 may be adhered to the lower first web 15 by any of various industrially known adhesion methods, such as adhesion with an adhesive (as shown in the figure) or heat. Seal welding, pressure welding, and other methods are appropriately selected. In this case, the heat seal welding can be performed by heating the pressurized fluid blown out from the plate-like peripheral edge portion 57, or by adding steam to the pressurized fluid.

The second web 16 is moved along a tangential path on the outer periphery of the partition forming surface 53, and is adhered to the first web 15 along the terrace-shaped peripheral edge portion 57 so that the partition, that is, the sheet-like packaging material is Form one or more small pouches. FIG. 1 shows an adhesive roller 36 as an example of an apparatus for performing the above adhesive formation. The adhesive roller 36 may be a male embossing adhesive device or a simple soft pressure roller. The second web 16 needs to be separated from the partition forming surface 53 to some extent for the purpose of preventing air inclusion, and must be moved from that position so as to make a tangent line to the partition forming surface 53. For that purpose, the second web is Partition forming surface 53
It was found that the direction could be changed by using a direction change roller near the. FIG. 1 shows the direction changing roller 35.
The direction changing roller 35 is located at a position slightly apart from the partition forming surface 53, and prevents the expelled air from adversely affecting the article to be packaged on the upper surface of the first web 15 before adhering to the second web 16. After the completion of the adhesion, the depressurization and the pressurization of the pressurized fluid are stopped, the sheet-shaped packaging material 18 is taken out from the compartment forming device (for example, by using the direction changing roller 37), and further processing steps or Send to packaging process.

FIG. 7 shows a plan view of the packaging material 18 adhesively formed into a sheet. In FIG. 7, the packaging material 18 is partially broken to show details of the upper second web, the article P to be packaged in each section of the packaged article 18, and the lower first web 15. Further, FIG. 7 also shows a state in which a plurality of articles to be packaged P (P ₁ , P ₂ ) are respectively housed in the compartments in the packaging material 18 which is adhesively formed in a sheet shape.

FIG. 8 shows a cross section of a part of the sheet-shaped packaging material 18 of FIG. The wrapping material 18 is made by the method and apparatus of the present invention. The height H of the packaging material 18 substantially corresponds to the depth of the compartment forming cavity, as described above. FIG. 9 shows another sheet-shaped packaging material 218 that is adhesively formed. This packaging material 218 has different shapes of individual compartments. The packaging material 218 of FIG. 9 is a pouch that can be used for individual tea bags and the like, and is made by the high-speed process and apparatus of the present invention. As shown in the figure, the plate-shaped peripheral portion formed on the pouch forming surface of the apparatus and method of the present invention has a pile-up of the material to be packaged on the peripheral portions surrounding the packaged portions of the first web and the second web of the pouch.
