Abstract:

A coextrusion feedblock is disclosed having a housing, a central extrusion channel, a coextrusion channel, a rotatable combining plane, a rotatable profile actuator, and a profiled bar mounted removably on the rotatable profile actuator. The central extrusion channel and the coextrusion channel pass through the housing. The rotatable combining plane and the rotatable profile actuator are positioned on opposite sides of the coextrusion channel so as to confront each other.
