The product Z is the same as in the first embodiment. It is to be noted that there is a case where the film is wound up without being cut and supplied to a user or the like.

In the first and second embodiments, the first temporary sealer 29, the second temporary sealer 33 and the main sealer 34 are used.
a, 34b or the sealer 34a in a stepwise manner means that the temporary attachment by the first temporary sealer 29 is of type 1
On the other hand, the purpose of securing each form of the type 4 bag body and the subsequent workability is that the temporary attachment by the second temporary attachment sealer 33 appropriately processes factors that tend to cause incomplete adhesion. In combination with the adhesion by the present sealers 34a and 34b or the present sealer 34a, the present invention prevents peeling and rupture of a required portion of the bag body, poor sealing, and contamination and deterioration of the film material.

That is, the front body film 1a, the film for the horizontal gusset 4, the seal tape 7a with the chuck or the seal tape 11 is a multi-layer, and the front body film 1a and the seal tape 7a with the chuck or the seal tape 11 are directly paired. There is a considerable thickness difference between the contacting portion and the portion contacting across the horizontal gusset film 4, and it is difficult to tightly seal the step. It is also conceivable to seal this multi-layer with the main seal at once, but when aiming at any of the above-mentioned parts, a minus appears on the other,
Setting it to a middle value will result in a lack of sharpness.

Therefore, as shown in the first and second embodiments, the second temporary sealing sealer 33 and the main sealers 34a, 34b or the main sealer 34a are used to seal step by step, so that the seal is as tight as possible regardless of the step. And also
In the second temporary sealer 33, the aim is brought into contact with a portion that is in contact with the horizontal gusset film 4 so that the portion is properly sealed. On the other hand, in the present sealers 34a and 34b or the present sealer 34a, the aiming is performed. By sealing in accordance with the portion where the film 1a and the seal tape 7a with chuck or the seal tape 11 directly contact, a sharp finished product can be obtained.

The two corners where the body film on the side where the sealing tape 7a with the chuck tape 7 or the sealing tape 11 is adhered and the horizontal gusset film 4 contact each other are obliquely adhered 9 in a C-shape to reinforce this part. Guidance or the like can be expected at the time of taking out stored items, but it is desirable that the diagonal bonding 9 be performed in conjunction with temporary attachment by the second temporary attachment sealer 33 having a relatively small difference in wall thickness. For the above-mentioned reason, the sealing may be performed in combination with the main sealers 34a and 34b or the main seal by the main sealer 34a.

After the main seal, the cooling bar 35
By cooling at a, 35b or 35a, it is possible to ensure the adhesion strength and maintain the stable adhesion of the required portion in contact with each of the seal tapes with chuck 7a, 7b or the necessary portion in contact with the seal tape 11, and It suppresses the generation of air bubbles in the bonded portion, prevents the bonded portion from easily peeling, and improves the appearance.

Furthermore, the temporary gusset film attaching means, the sealing tape with a zipper or the sealing tape with or without the diagonal adhering means at both corners of the transverse gusset film and the body film are included in the contact portion where the three parts overlap. Temporary attachment means, a required portion to be in contact with each of the body film and the male and female zippered seal tape or a required portion to be in contact with the seal tape, and a body film to which a contact portion with the seal tape with the chuck or the seal tape and the film for the horizontal gusset is temporarily attached. The four means of the main seal of the part and the means of cooling the main seal by the cooling bar may be operated independently, but two to four means are processed in series on one member (core). By doing so, the guideability can be improved and simplified, and the complexity of the device can be reduced. Reduction in the manufacturing cost of reduction and device space is achieved by assembling the bets.

The position of the upper edge 4b of the horizontal gusset film 4 is set at the upper end of the horizontal gusset film 4 if the horizontal gusset film supply means is located before the chucking tape supply means or the sealing tape supply means. When the edge 4b is set at a predetermined position of the body film and the horizontal gusset film supply means is located after the zipper-equipped seal tape supply means or the seal tape supply means, in addition to the above, the horizontal gusset use The position can also be set by setting the upper edge 4b of the film 4 at a predetermined position on the seal tape with chuck 7a or the seal tape 11.

By operating the apparatus of the present invention, types 1 to 4
It is also possible to manufacture a bag in a form other than the above-described form. For example, by applying a body film with a chuck to the apparatus in the first embodiment, a bag with a chuck having two chuck portions can be obtained.

Further, Embodiments 1 and 2 show basic embodiments, and utilizing this principle, for example, each supply means is not limited to only the embodiment. By making adjustments, a plurality of bags can be obtained at once, and it is also possible to develop mass production.
