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 (42) which provides a path (A) along which the products are advanced. A sealing support structure (58) as mounted on the frame for linear reciprocating movement along the path. A crank arm (72) is rotatably mounted on the frame for reciprocating the sealing support structure. Upper and lower sealing dies (81, 82) are mounted on the sealing support structure for linear movement toward and away from eaach other in a direction which is generally perpendicular to the path.
