ABSTRACT:
A method for manufacturing a web of interconnected bags from a semitubular web of material, in which pockets are formed at a first side of the web and a second side of the web adjacent a first of two longitudinal outer edges of the web. At least one continuous strip is inserted into the pockets before separation of the bags. The strips are cut to predetermined lengths, and their ends are fastened together. The web is welded together along transverse lines substantially perpendicular to the pockets for producing one bag at a time, which is conveyed transversely substantially perpendicular to the direction motion of the web. The pockets project at one of the two sides of the web beyond the pockets on the other side of the web substantially perpendicular to the direction of motion of the web. Each bag is welded and conveyed substantially perpendicular to the direction of motion of the web.
