ABSTRACT:
A stuffer crimper having a closed housing forming a heating chamber and a set of spaced rods supporting the core of crimped yarn and holding the core spaced from the walls of the housing. Choke members engage the sides of said core near the inlet end of said heating chamber to control the back pressure of the core. Steam under low pressure is introduced into the chamber between the walls and the core and is caused to permeate the core and act as a heat transfer agent to facilitate the setting of the crimp.
