ABSTRACT:
For the continuous formation of bags for containing bulk materials--in the form of granules, powders and the like--the end of the web (EN), from a new bobbin (BA) in readiness, is laid, with the surface to be welded on the outside, around a welding bar (18) carried by a movable element (12), and the bar (18) is positioned opposite a counterbar (20), along which the web (N) being exhausted from the previous bobbin (B) runs; bar and counterbar are brought close to one another to carry out transverse welding and cutting, in such a manner that a superimposed and welded edge (BS) emerges transversely from the continuous web thus joined, from the surface opposite that of welding. (FIG. 2)
