Title:
BAG MANUFACTURING MACHINE AND METHOD FOR MANUFACTURING PLASTIC BAG
Document Type and Number:
WIPO Patent Application WO/2019/163496
Kind Code:
A1
Abstract:
A first body material 1 is folded along a first folding line 10 so that a first folded part 13 is formed in the first body material 1. The first folded part 13 is then folded back along a second folding line so that a folded-back part 22 is formed in the first body material 1. A corner cutting mechanism 37 cuts a second body material 2 and the folded-back part 22 to form a corner cut part. When doing so, the corner cutting mechanism 37 protects the first folded part 13 and a base 28 of the first body material 1 from being cut.
