Abstract

An extrudate transport apparatus comprises a free floating roller assembly, wherein the roller assembly controls a rotational pitch of a cylindrical green ceramic extrudate as the green ceramic extrudate moves longitudinally from a first location to a second location within the extrudate transport apparatus. The free floating roller assembly has a predetermined effective weight and comprises a contact roller having a deformable outer surface for frictionally contacting an outer surface of the green ceramic extrudate in motion adjacent thereto, while maintaining a constant contact force upon said green ceramic extrudate.
