Abstract A SOURCE OF STEAM UNDER PRESSURE FEEDS A STEAM BOX FROM WHICH THE STEAM IS EMITTED THROUGH A NEDDLE VALVE INTO A CHAMBER. YARN IS PULLED THROUGH THE NEDDLE VALVE BY THE STEAM AND CRIMPED UNDER PRESSURE IN THE CHAMBER. A KURLED SURFACE MOVES AT A SPACED DISTANCE FROM THE END OF THE CHAMBER AND CARRIES THE CRIMPED MATERIAL AWAY. MOST OF THE STEAM EXITS FROM THE CHAMBER BEFORE THE YARN EXITS FROM THE CHAMBER.
