Document Type and Number:
WIPO Patent Application WO/2016/199863
Kind Code:
A1
Abstract:
The present invention enables a bag making machine to make a plastic bag using a bottom material without the need to feed the bottom material separately and with no risk of a displacement of a print design. First and second trunk materials (1, 2) are placed one upon the other, and are fed in the longitudinal direction. Further, before the trunk materials (1, 2) are placed one upon the other, a plastic film is slit along a plurality of longitudinal slitting lines (13, 14) to be divided into the first trunk material (1) and a plurality of bottom materials (3, 4). Thereafter, the bottom materials (3, 4) are guided by bottom material guide mechanisms (21, 28), and each bottom material (3, 4) is fed to the first or second trunk material (1, 2).
