この発明は熱可塑性の合成樹脂膜より製造され
た底ガゼツト折込み袋に底補強板をその製造行程
中に能率よく取付ける方法に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a method for efficiently attaching a bottom reinforcing plate to a bottom gusset folding bag made of a thermoplastic synthetic resin film during the manufacturing process. .

This type of bottom gusset type square bottom bag B generally has a handle 1 attached as shown in Fig. 8, or a bag with a 9
As shown in the figure, there is a bag B with a finger hole 2 drilled near the mouth edge of the bag. The bottom of the bag will sag and the shape of bag B will be significantly damaged. The current situation is that the waste is discarded afterwards, which is uneconomical as it depletes resources, and the increase in domestic waste is deteriorating people's lives.

底補強板としての役目をはたさなくなる。 Conventionally, there are some bags in which a piece of cardboard of a size that corresponds to the area of the square bottom is simply inserted into the bottom of this type of square-bottomed bag, but this paper board is inserted into each completed bag B one by one. This is quite troublesome and increases the cost of Bag B, and if you put vegetables or frozen foods with a high moisture content, this moisture will moisten the cardboard.
It no longer functions as a bottom reinforcing plate.

する方法がなかつた。 The applicant of the present application previously published Utility Application No. 58-78244 (undisclosed at the time of filing of this case), in which a hard reinforcing plate A was attached to the inside of this type of bag, and a bag that improved the drawbacks of the above-mentioned known technology. However, there was no way to efficiently manufacture the bags.

高くなり実用化をみていない。 That is, in the process of manufacturing bag B from bag material strip F in a conventionally known bag making machine, bag material strip F is sequentially bent or folded by many guide rollers and guide rods. Even if the hard bottom reinforcing plate A is attached to the bag material band F during the manufacturing process, the bottom reinforcing plate A cannot be bent or folded along the guide rollers and cannot be transported thereafter. It is considered impossible to attach the bottom reinforcing plate A to a bag making machine like this, and the only way is to manually attach the bottom reinforcing plate A to the completed bag B. However, this method costs less. The cost is too high to see practical application.

As mentioned above, the automatic bag making method with a reinforcing plate was thought to be extremely difficult, but this invention has made it possible to do so without increasing the processing cost of the product, preventing the product from losing its shape, and extending the number of times it can be used or its service life. The purpose of the present invention is to provide the market with a method that can fully absorb the increase in processing costs, to enable the production of highly fashionable bags, and to reduce municipal waste and save resources.

の製造方法。[Scope of Claims] 1. A half-folded bag material strip made of thermoplastic synthetic resin with one side edge folded into a gusset and the other side edge open, with the bag material strip surface horizontal and stretched in the longitudinal direction. Each bag is transported intermittently, and the entire transport process is carried out in approximately the same plane, and from the upstream side, the width of the bottom gusset is twice as large as the width of the bottom gusset, and the width of the gusset is larger than the transport dimension of one time of the intermittent transport. It is slightly shorter than the dimension obtained by subtracting twice the folding width dimension,
A rectangular hard bottom reinforcing plate that is heat-weldable to the bag material strip is attached to the inner surface of the gusset fold-in side edge of one of the upper and lower double gusset parts of the gusset fold-in side edge on the opposite side from the open edge of the bag material strip. Next, the bottom reinforcing plate held by the bag material strip is welded to the bag material strip at the part where it contacts the gusset folding part, and then the bottom reinforcing plate is inserted at intervals in sequence. A method for manufacturing a fold-in bag with a reinforced bottom gusset, characterized by welding only the bag material strip at the exact center between the plates in the full width transverse direction, and dividing this center in the transverse direction to sequentially manufacture individual bags. . 2 The method of thermally welding the bag material band and the bottom reinforcing plate is to soften and fuse the materials themselves, or at least soften the thermal welding material applied to the bonding surfaces at the positions to be thermally welded. 2. The method of manufacturing a fold-out bag with a reinforced bottom gusset according to claim 1, which is one of the methods of fusing.
