Means for Solving the Problems In the manufacturing method proposed above, the present inventor can easily attach a heading portion by making the shape of the fusing blade into a protrusion shape of the shape of the heading portion. We paid our attention and completed the present invention. That is, the present invention is a device having the following two aspects. (1) A thin film is laminated on the entire back surface of the core film, the thin film is folded back on the surface at the left and right side edges of the core film, and the leading edge from the left and right of the thin film is the central portion of the core film. Are laminated on the surface of the core material film so as to leave areas parallel to each other, and the thin film and the core material film are fused and fused at the positions of the upper edge and the lower edge of the core material film of the laminated structure. As a result, at least the right and left sides 2 formed by the surface of the core material film and the thin film facing the core film with the folded front edge as an opening are formed.
In a bag sheet having individual bag body portions provided on the surface of a core material film, when the upper edge or the lower edge of the bag sheet is fused, the fused edges are fused into a protrusion shape for a heading portion. A bag file book sheet, wherein a heading portion protruding from the edge of the bag is formed on the upper or lower edge of the bag body.

(2) A three-layer structure in which thin films are arranged on the front and back sides in a U-shaped cross-section structure with an area of a space parallel to the central portion of the opaque core material sheet, and the upper edge of the three-layer structure is formed. And a storage part formed by fusing the core material sheet and the bag film at the lower edge, formed between the core material sheet and the bag film,
In a bag bag for a bag file, which has at least four lateral insertion type storage parts having an opening toward the center, on the left and right sides of the core sheet, and the upper and lower edges of the bag sheet are fused. In the case of the bag file book, the fusing edge is fused into the protrusion shape for the heading portion to form a heading portion protruding from the edge of the bag at the upper edge or the lower edge of the bag body portion. Sheet.

The bag file book sheet of the present invention will be described in more detail with reference to the accompanying drawings. The bag file book sheet 1 of the present invention is formed of a thin film 3 and a core film 2. The thin film 3 is preferably transparent or translucent because the inside of the bag can be seen, and the thickness is 20 to 200.
A thin film of about μm can be used. The material is not particularly limited as long as it is a thermoplastic resin film having a certain degree of strength, and polyethylene, polypropylene, polyester, nylon and the like can be preferably used.

The core material film 2 of the bag file book sheet of the present invention is inserted as a core into the bag body in order to strengthen the rigidity of the bag and to reinforce the strength when the center of the bag file sheet is bound. The thickness is 80 to 30
It is a film sheet of about 0 μm. The core material film is
The next page is invisible, so translucent or opaque ones are preferable because the contents can be clearly confirmed. The material of the core material film is not particularly limited as long as it is a thermoplastic resin,
It is important to match the material of the thin film in order to increase the strength of the upper edge and the lower edge of the bag body fused by fusing. A laminated laminate film can also be used as the core material film 2. In this case, it is desirable that the films laminated on both the front and back surfaces of the laminated film are made of the same resin as the thin film 3 from the viewpoint of fusion strength.

The thin film 3 of the bag file book sheet of the present invention is as described in Japanese Patent Publication No. 1-36798.
The tube-shaped long film original film produced by the inflation film process and the continuous long film original film are continuously produced as raw materials. At the stage before the manufacturing process of the bag file book sheet of the present invention, it is desirable to print the roughening ink on the entire surface or a specific portion of the original film.

In the bag file book sheet of the present invention, first, the central portion of the lower film of the tube film is vertically cut open while continuously supplying the original film of the tubular film.
This is continuously supplied to the row of guide plates, the edge of the film is widened by the action of the guide plate, and the strip-shaped core material film 2 is inserted therein, and again by the action of the guide plate. The edge of the film is overlapped with the lower surface of the core material film so as to wrap the film 2.

At this time, the core film used has a width slightly wider than that of the tubular film. Therefore, by operating the guide plate, when the tip is stacked so that the core material film is wrapped with a thin film,
Since the tip of the thin film (corresponding to the openings 5 and 6) does not reach the central portion of the lower surface of the core material, the central portion of the core film is laminated in an exposed state. In this way, a long film laminate having the cross-sectional shape laminated in the same manner as the case where the cross-sectional shape of FIG. 2 is just inverted is formed. Next, the sheet for the bag file book of the present invention is completed by fusing the upper and lower edges of the bag body in a specific fusing step.

In the fusing step of manufacturing the bag file book sheet of the present invention, two types of fusing and heat insulating blades having different shapes for the upper edge and the lower edge are used. The two types of hot blades cut and separate the bag file from the long film and fuse the two files. For example, the upper edge of the bag file book sheet is fused with a hot blade having a projection shape corresponding to the shape of the index heading portion of the bag file book sheet of the present invention. Then, the lower edge of the bag file book sheet of the present invention is melted and cut by using a normal straight heating blade.

If a hot blade having a projection of a heading portion is also used on the lower edge, a sheet having a heading portion 4 on the lower edge of the bag file book sheet can be obtained. It is also possible to install the lower edge hot blade and the upper edge hot blade in parallel, and to simultaneously perform the fusing fusion of the upper edge and the fusing fusion of the lower edge. Since the two types of hot blades have different shapes for fusion cutting, the film having a width corresponding to the height of the index heading portion 4 is discharged as scraps. By this fusing step, three thin films on the front and back of the core material film are simultaneously fused to the core material film.
Since the thin film exists only on the back surface in the central portion of the core material film, one thin film and the core material film are fused at the upper edge and the lower edge of this portion. When the position of the long laminated raw material laminate that is passed under the fusing blade having the protrusion is shifted to the left or right, the heading portion 4 of the bag file book sheet can be changed to the left or right.

In this way, the bag file book sheets having the heading portions 4 at different positions can be manufactured by the same fusing blade. The heading portion 4 of the bag file book sheet of the present invention has a structure in which thin films are laminated on both sides of a core material film, and the upper edge and the left and right ridge line edges are fused in three directions. It is a certain projection section. In the present invention bag file book sheet, the heading section 4
It is characterized in that the core material of the bag body protrudes inside and is also used as the core material of the heading piece. That is, since the core material 2 extending from the inside of the bag acts as a core in the heading portion 4,
The headline will not bend or break.

As shown in FIG. 3, the bag file book sheet of the present invention is used as a file book by stacking a large number of sheets and firmly fusing the central portion by ultrasonic fusing or the like. You can also attach a thick cover. Also, as another method of heat fusion,
A method in which the laminate is fixed in a trapezoidal shape and a needle or a cylindrical punching blade heated to a high temperature is passed through the binding margin portion to fuse the respective sheets on the side surface is also a preferable method. Further, for example, five sheets of the bag file book of the present invention having the heading portion 4 only on the upper edge are laminated, and five sheets having the same shape are laminated upside down to fuse the central portion. When attached and fixed, a bag file book having 20 bag body parts is completed, and the index heading parts 4 can be installed separately above and below.

The bag opening of the bag file book is at the positions of the tips 5 and 6 of the thin file, and what is put in the bag is stored between the core film and the thin film on the front side, and the bag file is stored. When is closed, the opening faces the direction of the closed eye of the film book, so there is no risk of the contents falling. In addition, for example, since a roughening ink is printed on the thin film as a roughening treatment, it is possible to write on the heading portion with a pencil, a magic ink, a ballpoint pen or the like.

In the second aspect of the bag file of the present invention, the bag sheet has a three-layer structure in which the bag sheet has a three-layer structure in which bag films are arranged on the front and back sides of the opaque core material sheet. By fusing the core sheet and the bag film at the lower edge, which is a storage section formed between the core sheet and the bag film, a horizontal loading type storage section having an opening toward the center,
A bag file sheet having at least four on the left and right sides of the core sheet and the right and left sides thereof is preferable.

This is, for example, a bag file book sheet of an embodiment as shown in FIG. 5, which is composed of a core material sheet B and a bag film A. As shown in FIG. The bag film A is laminated in a U-shape on both sides with a core sheet sandwiched in between to form a three-layer structure. The bag film A is folded and laminated so as to wrap the front end of the core material sheet B. The plan view of the bag file book sheet of this embodiment appears as in FIG. Only the cross-sectional structure is different. The core material sheet B and the bag film A are fused and fixed by fusing at the upper and lower edges. Although the bag sheet having a structure in which the opening is directed toward the central binding margin C as described above has a complicated structure, a long tubular film is produced by the method proposed in Japanese Patent Publication No. 1-36798. It can be continuously and efficiently manufactured from a raw material and a long opaque core material sheet.

A core sheet B is used for the bag sheet as shown in FIG.
A bag-shaped storage portion is formed between one surface of the bag and the bag film A.
As a result, the same storage portion is formed on both sides of the core sheet B. Therefore, at least four storage portions can be formed on one bag sheet. Furthermore, if this bag sheet is divided into two upper and lower parts by horizontal dividing seals, it will be 8
A storage unit for individual pieces is formed. Further, the number of split seals can be increased to 3 and 4. In the bag file book sheet of the present embodiment, it is preferable to use an opaque core material sheet because it does not show through. If a transparent bag film A is used, the contents can be clearly seen from the outside of the bag, which is convenient when used for a sample book or a photo album.

[0019]

The file created by the bag file book sheet of the present invention has an advantage that it can be easily searched and an advantage that it can be continuously and efficiently manufactured. Further, since the heading portion extended from the bag body is reinforced by the core material,
Since there is no fear that the heading portion will be torn and the heading portion is not bent, there is an advantage that the heading description is easy to see.
