20090036286 | APPARATUS FOR MANUFACTURING A CIRCULAR BAG - An apparatus for manufacturing a circular bag is configured with two anvil half-sections that are movable relative to each other from an open position to a closed position. An ultrasonic sealing tool is provided that is movable towards and away from the anvil half-sections and configured to seal a lid portion to a sleeve portion of the circular bag.

20110082019 | Method of Manufacturing a Polypropylene Pinch Bag - A method of manufacturing a gusseted pinch bag from polypropylene. A sheet or seamless tube of polypropylene is provided. The sheet is preferably comprised of one or more layers of axially and/or biaxially oriented polypropylene. Perforation lines in a pinch pattern are formed in the sheet or tube. Preferably a laser forms a series of small, closely spaced holes in the sheet along the perforation line. The laser heats the plastic surrounding the holes, causing the polypropylene molecules between the holes to lose their orientation. Thus, the polypropylene in the perforation line between the holes is substantially weakened. If a sheet is used, it is folded into a gusseted tube and the edges are sealed together to make a tube. If a seamless tube is used, the tube is gusseted. In either case, a lateral force is then applied to the terminal tube, breaking the perforation line and separating the terminal tube from the sheet. The bottom end of the tube is then sealed, thereby forming a bag. | 04-07-2011 |
20110143902 | AUTOMATIC DISPLACER CLEARANCE ADJUSTMENT - An apparatus and method producing a plait-like portion on a tubular packaging casing, which accommodates a filling material includes a plait-like portion at least approximately free of filling material, extending along a longitudinal plait-axis. The apparatus comprises a first displacer unit with a first pair of displacer elements reversibly movable between an opened and a closed position perpendicular to the longitudinal plait-axis. A displacer clearance is created between the first pair of displacer elements, which surrounds the longitudinal plait-axis, in which the tubular packaging casing is being gathered, when the first pair of displacer elements is in the closed position. The apparatus comprises a second displacer unit with a second pair of displacer elements also being reversibly movable between an opened and a closed position perpendicular to the longitudinal plait-axis. A displacer clearance is created between the second pair of displacer elements, similar to first pair of displacer elements. | 06-16-2011 |
