Abstract
An apparatus for forming an extruded sheet product having an extruder assembly with a sheet die through which flowable material is delivered for sheet product formation and a roll stand assembly with a main frame and a roll stack sub-assembly on the main frame that cause flowable material from the sheet die to be formed into a sheet product. The apparatus further has a sub-frame assembly and a linear slide bearing assembly with 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 roll stand assembly along the travel path.
