Abstract
An apparatus for extrusion forming a sheet product having an extruder assembly with a sheet die through which a flowable material is delivered and a roll stand assembly made up of a roll stack sub-assembly and a sheet take-off sub-assembly. The roll stack assembly has first and second rolls between which a nip location is defined at which flowable material from the sheet die is delivered. The sheet take-off sub-assembly produces an advancing force upon a first sheet component made up of at least the first sheet layer. The roll stand assembly further has a coating system for applying a coating component to a surface on at least one sheet component advancing through the apparatus. The roll stand assembly is constructed to be reconfigured thereby to change a path traveled by the at least one sheet component and facilitate selective application of the coating component.
