Abstract

See full text

A zipper guide and spreader device for form, fill and seal apparatus comprises a package material guiding and spreading mechanism wherein a pair of articulated members have zipper guideways. The members are hingedly connected together and one of the members is hingedly connected to a fixed support. An actuator operates the articulated members from a biased relaxed position into an articulated material-spreading position wherein the material is spread for eliminating wrinkles before edge sealing across the material below the discharge end of the forming and filling tube.
