Abstract
A combined holding and stripper jaw apparatus is provided for use in a form, fill and seal packaging machine. The apparatus includes a pair of opposed holding jaws operated in reciprocating fashion to close and grasp the packaging film tube following the product filling step of the cycle. A stripper jaw is pivotally mounted to the underside of each holding jaw. The stripper jaws are each movable between a ready position adjacent the holding jaws and a strip position for stripping the product in the packaging film tube. Sealing jaws independently mounted between the holding and stripping jaws are separately cycled to close and seal the packaging film into a bag. As the sealing jaws close, a cam surface on the sealing jaws contacts an angled portion of the stripper jaws forcing the stripper jaws downward against spring tension to the strip position. In addition, the holding and stripper jaws include relief features in the edges contacting the packaging film for the venting of trapped air.
