Problems solved by technology

[0004] However, in this case, not only the side stay material but also the bottom stay material need to be specially supplied, and this supply mechanism complicates the structure of the bag making machine and causes a problem of high cost.
There is also a problem that the overall size of the bag making machine and the required space are increased due to the supply mechanism for the bottom stay plate material

Embodiment Construction

[0042] figure 1 Shown is the bag making machine of the present invention. The bag making machine is used to manufacture Figure 7 Bag making machine for plastic bags shown. Same as that shown in JP-A-2000-254984, Figure 7 The plastic bag has bag body parts 1, 2, side brace part 3 and bottom brace part 4, such as Figure 8 As shown, the bag body parts 1, 2 are overlapped in two layers, and the side support plate part 3 extends along the side edges 5 of the bag body parts 1, 2, and is folded between the two layers of bag body parts 1, 2 to be folded into two layers. fold. In addition, the bag parts 1, 2 and the side brace part 3 are heat-sealed along the side edges 5 of the bag parts 1, 2, and the heat-sealing line 6 is formed along the side edges 5 of the bag parts 1, 2. Furthermore, one end of the side spreader 3 is folded at an angle of 45°, and then folded in half between two layers of the side spreader 3 to form the auxiliary spreader 7 .

[0043] And, as described i...

Abstract

It is arranged that even if a bottom gusset member is not specially supplied, a bottom gusset can be incorporated into a plastic bag. As continuous trunk members (1, 2) are fed, they are guided by a trunk guide mechanism (16-29) and folded along a longitudinal fold like (8). Then, the folded portion (4) is folded back along a longitudinal fold-back line (10), whereby a twofold section is formed of the trunk members, with the continuous trunk members forming the trunk of the plastic bag, the twofold section forming the bottom gusset of the plastic bag.

Description

technical field [0001] The invention relates to a bag making machine for making plastic bags. Background technique [0002] As a plastic bag, a bag having a bag body and a bottom stay is used. The side stays can be assembled on this plastic bag. So far, bag making machines have also been developed and proposed. As the bag making machine described in JP-A-2000-254984. [0003] In the bag making machine of the above publication, continuous bag materials are stacked in two layers and conveyed in the longitudinal direction. In addition, before stacking the continuous bag material into two layers, the side gusset material is folded in half in advance, supplied to one layer of bag material, placed on it, and arranged in the width direction. Parallel to this, the base stay material is fed to a layer of bag material, placed on top of it, and properly folded in two. The bottom brace material extends in the longitudinal direction of one layer of the bag body material, and is disp...
