ABSTRACT:
The present invention relates to the integral extrusion of closure profiles and a film through a film die. The present invention provides an apparatus for integrally extruding a film and closure profiles from a single stream of molten material and, consequently, eliminating any joining problems between the film and the closure profiles. The present invention utilizes a removable die lip with removable profile wedges that mount in the die lip and extrude the closure profiles and a film together from a single stream of molten material. In this manner, the closure profiles and the film are integrally formed, and if a new closure profile design is desired, the present invention permits the quick and economical replacement of a removable profile wedge with another.
