Abstract
The improved filling pipe (1) is for use in liquid food packaging machines of the type wherein a longitudinally-sealed continuous tubular container (2) is formed from a web (3) of packaging material, and members successively clamp the tube at regularly spaced intervals for forming and transversely sealing packages filled with product. The filling pipe (1) is locatable axially of the continuous tubular container and has a rigid damper member (4) affixed to and surrounding a portion of the filling pipe (1). The rigid damper member (4) is locatable at a position which is radially spaced from the inner wall (2a) of a continuous tubular container (2) and entraps an air pocket (5) surrounding a portion of the filling pipe (1) for dampening motion of liquid product (20) relative to the filling pipe (1) in a packaging material tube (1) during operation of a liquid food packaging machine.
