ABSTRACT:
A stuffer box crimping unit provided with a crimping chamber and two feed rolls associated with the chamber and located upstream thereof, has pressure disks associated on both sides in side walls of the crimping chamber at the level of the nip between the two feed rolls. These two disks are not only made from a material provided for wear, but also from a separate carrier disk made of appropriate material. The carrier disk is a wear element shaped like a lid and made of the nonferrous metal intended for wear in the direction facing the pressure roll nip. This wear element is readily replaced and there is no need any longer for regrinding the wear surfaces of pressure disks so that the disks can be reused.
