  • Continuous motion sealing apparatus for packaging machine
    Publication number: 20030159401
    Abstract: A sealing apparatus is especially adapted for a packaging machine which wraps spaced-apart products with a tubular film. The apparatus includes a frame which provides a path along which the products are advanced. A sealing support structure is mounted on the frame for linear reciprocating movement along the path. A crank arm is rotatably mounted on the frame for reciprocating the sealing support structure. Upper and lower sealing dies are mounted on the sealing support structure for linear movement toward and away from each other in a direction which is generally perpendicular to the path.
