Patent ID: 8021140

Claim:
An apparatus for forming an extruded sheet product, the apparatus having an upstream end and a downstream end towards which a completed sheet product is directed, the apparatus comprising: an extruder assembly with a sheet die through which flowable material is delivered for sheet product formation; a roll stand assembly comprising: a) a main frame; and b) a roll stack sub-assembly comprising a plurality of rolls on the main frame that cause flowable material from the sheet die to be formed into a sheet product; a sub-frame assembly; and a linear slide bearing assembly comprising at least one rail defining a travel path for the main frame and through which the main frame is guided in movement relative to the sub-frame assembly thereby to selectively vary relative positions of the sheet die and at least a part of the roll stand assembly along the travel path, wherein the apparatus further comprises a temperature control system through which temperature of components on the roll stand assembly can be selectively controlled, and the main frame is movable along the travel path relative to the temperature control system.
