Abstract

The invention provides a coextrusion feedblock (500) having a flow adjuster (50), a viscosity compensation device (100), an actuator (110), a central extrusion conduit (300), and a coextrusion conduit (200). The invention also provides a coextrusion profiling insert assembly constructed to be mounted in a coextrusion feedblock (500). The insert assembly has a flow adjuster (50), a viscosity compensation device (100), and an actuator (110). The insert assembly when mounted in the feedblock (500) has a coextrusion conduit (200) extending between the flow adjuster (50) and the viscosity compensation device (100). The actuator (110) is adjustable to apply force to bend the viscosity compensation device (100) and thereby adjust a gap height of the coextrusion conduit (200). Also provided is a method of operating a feedblock (500) having a viscosity compensation device (100) comprising a flex region, a central extrusion conduit (300), and a coextrusion conduit (200). Force is applied to bend the flex region of the viscosity compensation device (100) and thereby adjust a gap height of the coextrusion conduit (200).
