より使用される。 Various types of filing bag-like sheets have been proposed for organizing and storing office documents, photographs, etc., and for example, a bag made of transparent film with an opening at the top and a mount inserted into the bag is common. In this conventional example, a plurality of holes are formed on one side edge of the bag, and the bag is used by binding it with a well-known binder.

程を殊更に簡略化することには限界がある。 However, in the conventional example, there is an inconvenience that the backing paper moves around in the bag, and there is also a disadvantage that two steps are required during manufacturing, including inserting the backing paper into the bag after making the bag. In this regard, the present inventor has already proposed a bag in which a core material made of a synthetic resin sheet is used in place of the mount, and the core material is welded to the bag at the same time as the film is used to make the bag. However, even in this case, complicated folding of the film, which is unique to bag making, is required, and there is a limit to further simplifying the process.

工程；とから成る点にある。 An object of the present invention is to break away from the conventional concept of bag making and to provide a method for manufacturing a bag-like sheet for filing very simply. In particular, according to the invention:
It is possible to simplify the folding process that conventionally accompanies bag making. Furthermore, by using a tube-shaped film that is generally supplied by inflation molding, it is possible to easily provide a so-called double-opening sheet, that is, a bag-shaped sheet for filing, which has a pair of left and right bag portions. The present invention is characterized by a film that covers the core material symmetrically with respect to the center line of the sheet-like core material, and the bag portions are formed in pairs on the front and back sides of the core material and open oppositely. 1. A method for manufacturing a bag-like sheet for filing in which a continuous long tube-like film is cut along approximately the diameter; A step of separating the pair of strip-shaped films from each other at a predetermined distance; After expanding at least one of the opposing cut edges of the pair of strip-shaped films so as to separate them from each other, the two cut edges are brought back into close proximity again. The process of forcing;
In the step, a continuous long sheet-like core material is inserted between a pair of strip-like films from the expanded space of the film cut edge, and the film cut edge is returned to the central line of the width of the core material. The method consists of the following steps: covering both the left and right portions with a pair of half-folded strip films; and fusing and welding the core material and the film in the width direction at a predetermined interval in the longitudinal direction.

われる。 The present invention will be described in detail below based on the illustrated embodiments. FIG. 1 shows the overall outline of the manufacturing method according to the present invention, in which a roll 1 is a wound body of a tube-shaped synthetic resin film that has been inflation-molded, and a tube-shaped film 2 that is unwound from the roll 1 is Transparent or translucent. Further, the roll 3 is a wound body of a synthetic resin sheet that is slightly thicker than the film, and the sheet fed out from the roll 3 is used as a sheet core material 4, which will be described later, and is preferably colored yellow or the like. There is. The film 2 and the core material 4 are made of the same synthetic resin material and can be suitably welded to each other by heat. The tube-shaped film 2 unwound from the roll 1 is cut approximately along its diameter by a cutting device 5 such as a slitter. Accordingly, as shown in FIG. 2, by cutting the film 2, the film 2 constitutes a pair of strip-shaped films 2a and 2b which are half-folded to have a substantially U-shaped cross section. Next, the pair of strip-shaped films are separated from each other so as to have a predetermined distance S from each other (separation step). Also, a pair of belt-shaped films 2a,
2b are mutually expanded so as to separate at least one of the opposing cut edges, in the example shown, the lower edges 2c and 2d, and then both edges 2c and 2 are opened again.
d is returned to the close position (expansion step and return step). On the other hand, the elongated sheet-like core material 4 drawn out from the roll 3 is inserted between the pair of strip-like films 2a and 2b in the expansion process, and is moved to the left and right sides of the center line with respect to the width of the core material 4 through the return process. Both parts are covered with a pair of half-folded strip films 2a and 2b (core insertion and integration step). These separation steps, expansion steps, return steps, and core material insertion and integration steps are automatically performed via a guide device 6, which will be described later.

The outer edge of the horizontal portion 23 has an outwardly sloping flared edge 25, which is followed by a straight edge 26 extending parallel to the axial direction. The vertical portion 24 is gradually widened so as to be gradually taller in the direction from the expanded edge 25 to the straight edge 26, and the width of the wall increases from the narrow wall portion 24a to the wide wall portion 24b. The angle with respect to the horizontal portion 23 gradually increases from an acute angle, and the widest wall portion 24b is approximately 90 degrees with respect to the horizontal portion 23.

For a filing, in which a film covering the core material symmetrically with respect to the center line of the sheet-like core material forms bag portions that open in pairs on the left and right sides of the core material and open opposite to each other on both sides of the core material. A method for producing a bag-like sheet, comprising: cutting a continuous long tube-like film along its diameter; and cutting a pair of strip-like films into half-folds having a substantially U-shaped cross section. a step of separating each other at a predetermined distance; a step of expanding at least one of the opposing cut edges of the pair of band-shaped films so as to separate them from each other, and then returning the two cut edges to be close to each other again; In the process, a continuous long sheet-like core material is inserted between a pair of belt-like films from the expanded space of the film cut edge, and the width of the core material is adjusted left and right with respect to the center line by returning the film cut edge. A filing bag comprising the steps of: covering both parts with a pair of half-folded strip films; and fusing and welding the core material and the film in the width direction at a predetermined interval in the longitudinal direction. A method for manufacturing a shaped sheet.
