ABSTRACT:
Process and apparatus for the manufacture of a valved sack with a self-sealing valve in which at the end of a transporting device for an open web of the sack material, shortly before the sack material is fed into a tube-forming zone, a valve-manufacturing unit is located, preferably above the material web path, in which unit valves are produced from a stock reel of paper and fed in a positioned manner to the open sack web, which has been pre-glued into fine zones. The pre-fabricated paper valves are then brought in contact with the pre-glued open sack web and the valve sleeve is securely glued into the sack in a gluing zone within the apparatus.
