Abstract
An apparatus and method for stripping the end seal area in a vertical form, fill and seal machine. First and second wiper members are secured to the sealing jaws and extend toward the film tube being formed, filled and sealed. The wiper members have engagement portions vertically staggered or offset from one another which engage opposite sides of the film tube for the purposes of stripping. The stripping apparatus and process can be used with intermittent machines which use film reversal for stripping, as well as continuous motion machines which always advance the film in the forward direction.
