ABSTRACT:
A method of manufacturing folding paper sacks, especially gusseted sacks, wherein each sack is shaped out of a tubular section separated from a single- or multiple-layer tubular web and closed at both ends with folded bottoms is characterized in that each tubular section continues to be conveyed uninterruptedly parallel to the direction of travel of the tubular web once it has been separated from the tubular web and the forward and/or rear ends of the tubular sections are shaped during the continuous pass by prefolding and crimping over and by the application of adhesive to the folded bottom, transversely to the direction C of travel, and accordingly sealed. The machine for carrying out the method is characterized by, first, an initial folder with a transverse adhesive applicator for the rear end of the tubular section downstream of a deflection roller that is in turn downstream of the tube-forming station and, second, by another folder with another transverse adhesive applicator for the forward end of the tubular section, with both folders and both adhesive applicators operating transversely with respect to the direction of travel and positioned one following another in the direction of travel.
