Abstract

The method is used for the production of a web of interconnected bags from a half-tube web consisting of a material which is capable of being adhesively bonded and/or sealed. In the region of the first of the two longitudinal outer edges running in the direction of feeding of the half-tube web, firstly at least one continuous strip is fitted in each case on the top side and on the underside of the half-tube web in pockets which are continuously integrally formed on the web during its feeding, before the separation of the bags, and the two parts of the half-tube web lie loosely one on top of the other in the region of the second longitudinal outer edge which is parallel to the first. Then, the strips are cut to length and their ends are interconnected and the half-tube web is sealed in a cyclical manner transversely, preferably perpendicularly with respect to the feeding direction to form in each case one bag, which is transported transversely, preferably at right angles to the feeding direction and all of these bags are interconnected. In this arrangement, either the pocket of the top side or that of the underside of the half-tube web protrudes beyond the respective other pocket, transversely with respect to the feeding direction, to form the first longitudinal outer edge. Every bag, which is sealed transversely with respect to the feeding direction and is transported in a direction which likewise runs transversely with respect to said feeding direction, is transported by one bag length. Then, the half-tube web is further transported by a bag width and with its first longitudinal outer edge overlaps, in an overlapping region, the second longitudinal outer edge of the bag which is transported transversely with respect to the feeding direction. Finally, the overlapping region is sealed by means of a sealed seam to connect two bags lying one behind the other in the longitudinal direction of the bags.
