Abstract (en)
[origin: US2017334608A1] A longitudinal method for producing a side-gusseted bag includes providing an incision extending in a transverse direction in a bag film for each side-gusseted bag in such a way that, in the case of a subsequently formed side-gusseted tube, the incision extends over both side gussets and a first front wall that is situated between the side gussets. Proceeding from the incision, the first front wall, together with the corresponding parts of the side gussets, is folded back, on which a separate film section is placed and fastened in the folded-open region. The folded-over section is folded back in such a way that all connecting seams of the separate film section extend in parallel to each other in the transverse direction.
