Description of the Related Art Generally, a board-shaped article (a board-shaped article) containing sushi, bento, Japanese confectionery, western confectionery, etc., must be held horizontally and carried in order to protect the contents. Conventionally, such articles were carried by wrapping them in a cloth or hanging a center part with a string, but in recent years, simpler handbags for plastic film boards have been used. It became so. However, many handbags made of plastic film for board-like articles have drawbacks such as the bags being easily broken when hung and having poor appearance. The inventor of the present invention has proposed in Japanese Utility Model Laid-Open No. 59-60916 a handbag for a disk-shaped object having the shape shown in FIG. That is, the board-shaped bag 1
And a handbag portion 2 capable of holding the bag body horizontally, provided with an opening 3 which opens to the left and right along a center line of the upper surface of the bag body, and an edge of the opening. Two tape-like films are stretched from one periphery of the bag body portion to the other periphery along the two sides, and both ends of each tape are fixed to the periphery of the bag body portion. One side edge and the left and right edges of the opening are fixed separately on the left and right,
It is a handbag for a disk-shaped object provided with finger holes 4 in the center of the left and right edges of the opening. FIG. 1 (a) is a plan view of the bag for a board-like object, FIG. 1 (b) is an end view of a section cut along the line AA, and FIG. 1 (c) is a section cut along the line BB. It is an end elevation. This carrying bag for board-shaped objects can be stored even with heavy board-shaped objects, and can be kept horizontal even if the weight of the board-shaped object is uneven, so it is widely used widely. It became so. However, for light-weight disk-shaped objects, this bag-shaped bag for disk-shaped objects is slightly excessive in quality, and can be easily manufactured with simpler processes. The development of a handbag has been desired.

While transporting a long tube-shaped plastic film, (1) a belt-shaped film having V-shaped gusset folds on both side edges, and (2) a heat-insulating pedestal between the V-shaped gusset folds. Insert the outer film and the gusset-folded inner film one by one at the width of the bag body by pressing the heat welding blades from both sides of the tray, and (3) the belt-like film at the width of the bag body. Cut at the welding wire,
(4) Cut the band-shaped film at the position of the center line in the longitudinal direction, (5) Form an arc-shaped notch at the boundary between the storage part of the welding edge and the hand-held part, and (6) Create a finger hole in the hand-held part It consists of each step of punching. FIG. 5 is an explanatory view of one embodiment of the method of the present invention, and FIG. 6 is a sectional end view of a tubular film. The long tubular plastic film 13 shown in FIG. 6A is sent to a gusset 14 to form a band-like film 16 having V-shaped gusset folds 15 on both side edges shown in FIG. 6B. If necessary, a band-shaped film having a smaller V-shaped gusset fold having the shape shown in FIG. 6C can be formed on the two outer fold lines of the V-shaped gusset fold. A long tube-shaped plastic film inflated by the internal air pressure is continuously supplied to the inlet of the circular gusset, and the gusset is folded.
The outlet of the gussetter has the same shape as that of the gusset-folded film as shown in FIG. The cross section of the gusset changes gradually from the circular shape at the entrance to the exit shape, and the film is gradually folded into the shape of a folded gusset film while moving through the gusset. The gusset folded belt-like film that has exited the gussetter outlet is sandwiched between nip rolls (not shown) and sent to the next step. By sandwiching between the nip rolls, the air in the tube-shaped plastic film does not flow over the nip rolls, and the gusset folded belt-like film can stably maintain its shape.

形成することが可能となる。Next, in the method of the present invention, the heat-insulating pedestal 17 is inserted between the folds of the V-shaped gusset fold, and the heat welding blades 18 are pressed from both sides of the pedestal, so that the outer film and the gusset fold are folded. The set of inner films are welded one by one for each width of the bag. As shown in FIG. 5, two sets of upper and lower pairs of hot welding blades can be used apart from each other by the width of the bag, or one set of upper and lower pairs of hot welding blades can be used. Only by using the single-pitch transfer, the gusset-folded band-like film is moved by the width of the bag by the one-pitch transfer, and welding can be performed for each width of the bag. It is sufficient to apply the welding only to the V-shaped gusset-folded portion serving as the storage portion of the handbag for the disc-shaped object. However, even if the two-layered film serving as the handheld portion is welded, the two-layered portion is used. There is no particular problem because the welded portion is cut and removed last. In terms of work, it is rather easy to weld the overlapping portion of the film serving as the hand-held portion, and it is preferable to weld over the entire width of the band-shaped film because the shape retention of the film after welding becomes good. In the method of the present invention, the heat welding blade is
So that two welding edges of adjacent bags are formed at the same time,
It is preferable to adopt a structure in which two welding lines are simultaneously formed with a slight gap by one heat welding blade. In the method of the present invention, the heat-insulating pedestal is inserted between the folds of the V-shaped gusset fold, and the heat welding blades are pressed from both sides of the pedestal to be welded. Are welded one by one, and the four films in the gusset folded portion are not welded together. The gusset-folded outer film and the inner film are welded one by one to form a W-shaped storage portion of the board-shaped handbag of the present invention, and the two W-shaped outer folds are formed. The line can be opened to form a horizontal bottom.

る。In the method of the present invention, the band-shaped film which is welded at each bag width to form the welding line 19 is cut at each bag width so that the welding line is formed at both edges of the W-shaped storage portion. , Cut at the position of the center line in the length direction of the band-shaped film, form an arc-shaped notch at the boundary between the welding edge of the storage portion and the edge of the hand-held portion, and punch out a finger hole in the hand-held portion to cut out the board of the present invention. The carrying bag 20 for articles is completed. By cutting at the position of the center line, one bag for the disk-shaped object of the present invention is obtained from each side of the strip-shaped film. There is no particular limitation on the combination of these cutting, notch forming and finger hole punching steps, and in the embodiment shown in FIG. 5, all of these operations can be performed in one step using the punching blade 21 and the cradle 22. For example, after cutting for each width of the bag body, cutting at the position of the center line in the longitudinal direction of the band-shaped film, forming an arc-shaped notch, and punching of a finger hole are simultaneously performed in separate processes. Alternatively, it is also possible to perform all of these steps sequentially as separate steps.
