Abstract (en)
[origin: EP0167717A1] 1. Process for producing paper bags, especially multi-layer gusseted bags, with a staggered closing flap, from a paper tube which, if appropriate, is multi-layer (1, 1a; 2, 2a), characterized in that the paper tube is cut off smooth and, starting from the end edge (4) thereby formed, is slit along the longitudinal outer folding edges (9) according to the length of the closing flap, and subsequently one of the tabs thereby formed which, if appropriate, is multi-layered (1, 2), is bent back transversely relative to the longitudinal direction of the bag, and the other tab is cut back.
