Abstract

Abstract A web of bag blanks, a method of making the web, and apparatus and method for filling and sealing the bags in the web. The web is formed as a continuous tube having spaced, transverse seal lines extending from a lower edge of the web to a point short of the upper edge. The bags are filled and sealed on a machine having an elongated filling pipe which is threaded into the tube between its upper edge and the upper ends of the transverse seal lines. After the bags are filled, a continuous, longitudinal, seal line is formed, intersecting the upper ends of the spaced seal lines to seal the filled bags. The tube is then severed intermediate its upper edge and the continuous longitudinal seal line to separate the filled, sealed bags from the filling pipe.
