Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Use and Outline of the Invention] The present invention relates to a method for manufacturing a pocket mount, which comprises covering a front surface and a back surface of a strip-shaped sheet with a two-folded coating film on its front and back sides, and then forming a required portion. In a method of manufacturing a pocket mount that is welded and then divided into strip-shaped sheets that are covered with a covering film, the width of the strip-shaped sheets is set to two mount sheets, and the mount sheet that is continuous in the vertical direction is used. Between each other, it is configured to have a notch or a long hole that opens to the side of the strip-shaped sheet at a position corresponding to the dividing position, and these long holes or the notches are staggered in the longitudinal direction of the strip-shaped sheet. By arranging them, it is possible to secure the running strength when transferring the strip-shaped sheets, to ensure the running stability of the strip-shaped sheets, and to increase the coating depth of the covering film on the mount sheet. It is intended to be so.
It also enables continuous production of so-called clear holders.

[Prior Art and its Problems] As shown in FIG. 9 and FIG. 10, the pocket portions (20) (20) for accommodating paper sheets such as photographs are arranged side by side on the opposite side of the binding side, A so-called pocket-type album has been widely used, and this album mount has heretofore been a bag-shaped cover film that is opened from the side edge of the mount sheet (1) that has been cut into a predetermined size and corresponds to the pocket portion. (2) was covered, and the required part was welded or adhered from the front and back. When the cover film (2) is attached to the mount sheet (1) by welding, the pocket (2
A certain number of point seal parts (11a) (11) between (0) and (20)
a) is provided.

This method is not suitable for mass production because the mounts are manually manufactured one by one.

Therefore, a method disclosed in Japanese Patent Laid-Open No. 58-219098 has been proposed as a solution to this problem and to enable continuous production of the mount.

This method, as shown in Figure 11, mount sheet (1)
A strip-shaped sheet (10) in which (1) is continuous in the longitudinal direction is run, and a covering film (2) folded in two in this running region is coated on a predetermined region of the strip-shaped sheet (10), and in a subsequent step. Weld required area and pocket (20)
After forming (20), one mount sheet (1) (1)
It is designed to be divided into two parts.

According to this prior art method, the strip sheet (10) is
A punching section for punching a portion corresponding to the welded portion into a predetermined shape (2) While passing through the covering section welding section cutting section of the covering film (2), a strip-shaped sheet (corresponding to the width of one mount sheet (1) ( 10) becomes the mount sheet (1) having the pockets (20) (20), and this mount sheet (1) (1) can be continuously produced.

However, with this conventional one, the product stability is poor and the running stability of the strip sheet (10) is poor, and the production efficiency is not sufficient.

 This is for the following reason.

In this conventional one, the line seal portion (12a) corresponding to the dividing position of the strip sheet (10) and at the edge of the pocket portion (20).
The notch holes (5) and (5) are provided at the locations where This notch hole (5) is used to improve the finish of the product.
Needs to be set so as to reach the entire width of the covering area of the covering film (2). So, in this conventional one,
A long hole having a length reaching almost the entire covering area of the covering film (2) is used as the notch hole (5). Therefore, in the area where the notch holes (5) are formed, a certain amount of the binding sheet side (a binding side side connecting portion (14a)) of the mount sheet (1) and the end of the covering film (2) on the covering side are very small. With the portion (covering side side connecting portion (14b)), only one mount sheet (1) is connected to each other.

By the way, when the belt-shaped sheet (10) is run in the longitudinal direction, the belt provided in each section pulls the belt-shaped sheet (10) in the production process. Both ends of the formation area, that is,
The covered side connecting portion (14b) and the binding side connecting portion (14a)
Concentrate on. However, since the total length of the two connecting portions is short, there is a high risk that the connecting portions will be cut when the belt-shaped sheet (10) is running, and the mount sheet (1) can be stably produced. I can't.

In particular, when the ratio of the pocket portions (20) (20) to the lateral width of the mount sheet (1) becomes large, the mutual connection width of one mount sheet (1) almost disappears, and the running of the belt-shaped sheet becomes impossible. Therefore, a pocket mount of this type cannot be produced in reality.

By shortening the length of the notch hole (5), the covered side connecting part (14
When the width of b) is sufficiently secured, the risk of disconnection of the connecting part as described above can be eliminated, but in this case, a large length is added to the edge of the pocket part (20) located in the dividing part. Non-welded portion (corresponding to the covering side connecting portion (14b)) is generated, and in this case also, the finished product becomes insufficient.

In order to eliminate such inconvenience, the present applicant has already proposed that
Proposed the method of 62-23797. In this method, a pair of mount sheets (1) (1) are symmetrically juxtaposed to each other and a covering film (2) is applied from both sides of a strip-shaped sheet (10) having a width and a type.
(2) is covered, and in this case, the connecting width between the pair of mount sheets (1) and (1) arranged in parallel and the pair of mount sheets following this is doubled,
Even if the length of the notch hole (5) is increased, or even if the notch hole (5) is formed as a notch opening to the side edge of the belt-shaped sheet, the stability of the transfer of the belt-shaped sheet can be ensured. However, even in this case, when the ratio of the pocket portions (20) (20) to the lateral width of the mount sheet (1) becomes large, the width of the connecting portion becomes extremely small, and the stability of the transfer of the belt-shaped sheet (10) is improved. Cannot be secured.

* Regarding the invention of claim 1 (Technical problem) In the present invention, after the covering film (2) folded in two from the side edge of the strip-shaped sheet (10) is covered in a range corresponding to the pocket portion (20). , Front and back cover films (2) (2)
Weld and seal the required parts of to form the pocket (20),
Pocket portions (20) (20) at both end positions of one mount sheet (1) and penetrating and welding the mount sheet (1)
In the method for manufacturing a pocket mount by dividing it at the line seal part (12a) at the edge of ", the strip sheet (10) in the production process is produced even if the coverage of the pocket part (20) on the mount sheet (1) becomes large. ) Is to improve the stability of driving and improve productivity.

(Technical Means) The technical means of the present invention taken to solve the above-mentioned problem is that "the width of the belt-like sheet (10) is set to be twice the width or the length of the mount sheet (1). The line seal portions (12a) (12a) are formed on both sides of the strip-shaped sheet at predetermined intervals, and the line seal portions are arranged in a zigzag pattern along the longitudinal direction of the strip-shaped sheet (10). ) Through hole or notch is formed at a position corresponding to each of the seal portions,
A step of covering the strip-shaped sheet (10) with the cover film (2) folded in two from both sides, and then welding the front and back cover films (2) corresponding to the respective seal portions to each other;
After this welding step, a step of separating and cutting each mount sheet (1) is provided ”.

(Operation) The above technical means of the present invention operates as follows.

The strip-shaped sheet (10) has on both sides thereof at least through holes or notches corresponding to the line seal portions (12a) (12a), but the portions corresponding to the line seal portions (12a) (12a) are not formed. They are arranged in a zigzag pattern in the longitudinal direction of the strip-shaped sheet (10) and are continuous at predetermined intervals. Therefore, when the belt-shaped sheet (10) is made to travel in a manner in which tension is applied, the tension concentrates on the connecting portion of the portion that coincides with the line seal portion (12a). Belt-shaped sheet (10)
Is at least more than half. Therefore, this connecting portion exerts sufficient strength during traveling in a tensioned state.

The covering films (2) and (2) folded in two from both sides of the belt-shaped sheet (10) running under the above conditions are the belt-shaped sheets (1
The required areas on both ends of 0) are covered, and then the covering films (2) and (2) on the front and back are welded to each other at the required portions.
At the same time as or after this welding, each mount sheet (1) is divided and cut, that is, the line seal portion (12).
A part corresponding to (a) (12a) is cut, and the strip-shaped sheet (10) is separated into right and left parts to form a pocket mount.

(Effect) Since the present invention has the above configuration, it has the following unique effects.

Since the belt-shaped sheet (10) having the line seal portions (12a) (12a) runs in such a manner that its connecting portion exhibits sufficient strength against tension, there is a risk that the belt-shaped sheet (10) will be cut during the running. And the stability of production is secured.

Further, even if the length of the long holes or notches corresponding to the line seal portions (12a) (12a) is set to be long, the running stability of the belt-shaped sheet (10) can be ensured, so that the pocket for the mount sheet (1) can be secured. The coverage of the part (20) can be increased.
In a special case, it is possible to continuously produce a so-called clear holder in which almost all of the mount sheet is a pocket portion.

* Regarding the invention of claim 2 The invention of claim 2 is a manufacturing method in which the mount sheet (1) of the invention of claim 1 is of a type in which a plurality of pockets (20) (20) are continuous in the longitudinal direction. For this purpose, the specified means is "the mount sheet (1) is provided with a plurality of pocket portions (20) (20) between the line seal portions (12) (12), The step of forming point seal parts (11a) (11a) located between the parts (20) (20) and penetrating and welding the mount sheet (1) is provided, and the lateral width of the strip-shaped sheet (10) is mounted. It was set to twice the width of sheet (1). "

By adopting this configuration, a plurality of pocket parts (20) and (20) are formed before separating and cutting the mount sheets (1) and (1), so that the so-called pocket-type alvar unit is continuous. Will be able to produce.
