PACKAGING MACHINE WITH CONTINUOUS SEALING JAW MOVEMENT |
摘要 |
An apparatus for cross sealing a continuously moving plastic tube, such as to form bags for packaging in a form-fill-seal packaging machine is disclosed, along with a related method. The tube is fed continuously between a pair of opposed sealing jaws (10, 11) that move toward and away from each other in a polygonal path. Substantially continuous sealing pressure is provided between the jaws during a sealing pattern of movement along the path, with the remainder of the path including a return pattern of movement away and back towards the sealing zone. Each sealing jaw is carried on a bridge extending between dual gear assemblies (25, 26). The sealing pattern of movement along the path is substantially linear so as to provide highly efficient sealing. |
