Method and apparatus for unfolding folded plastic film for use in forming a packaging tube

摘要

An apparatus for unfolding folded plastic film having a first side joined to a second side along a longitudinal folded edge for use in forming a packaging tube. The folded film travels through a slot and the folded sides are separated at their respective outer longitudinal edges. The longitudinal left side is conveyed toward and over a guide plate left side edge and then over a left form tube section. The longitudinal right side is conveyed toward and over a guide plate right side edge and then over a right form tube section. The longitudinal middle section including the longitudinal folded edge and part of both the first and second sides adjacent the longitudinal folded edge is conveyed toward and over guide plate angular edges and then onto a carrying surface.
