ABSTRACT:
A process for stuffer box crimping of a yarn of synthetic thermoplastic filaments wherein the discharge resistance on the yarn plug formed in the stuffing chamber is increased or reduced in response to a continuously measured value of advancing pressure of the yarn plug within the stuffing chamber, preferably in response to the frictional force between the yarn plug and an axially movable inner wall surface of the stuffing chamber. Suitable measuring and control means may be provided to increase or decrease the discharge resistance in response to the difference between the measured value of the advancing pressure and a predetermined constant value.
