Abstract
A stripping/sealing assembly and method for a vertical form, fill and seal machine. The stripping assembly comprises a rotatable master axis including a pair of oppositely rotating primary axes. A stripper may be associated with each of the primary axes, each stripper being located in a mount. A slave axis, comprising a pair of rotatable cranks mounted on central axes, is provided for displacement of the mounts in unison toward and away from the primary axes during rotation. By judicious retarding and then accelerating of the rotation of the cranks in relation to the primary axes, the stripper/sealer dies traverse linear paths along the tubular film to strip and seal the tubular film. The method provides adjustable seal dwell time, stripping and seal cooling time all programmable in software.
