ABSTRACT OF THE DISCLOSURE An accumulatorless process is disclosed for bounce crimp texturizing thermoplastic yarn. The process includes the step of supplying at least one drawn multi-filament thermoplastic yarn to a bounce crimp texturizer thereby texturizing the yarn. The texturized yarn is collected by winding the yarn on a rotating winder spindle. The relative tension on the texturized yarn is sensed at a position between the bounce crimp texturizer and the winder spindle and the rate of the yarn wind-up is reduced when the sensed tension on the texturized yarn exceeds a predeter- mined tension value and the rate of the yarn wind-up is increased when the sensed tension on the yarn is equal to or less than the predetermined tension value. The pre- determined tension value is selected at a value to ensure that the freshly texturized yarn is discharged from the texturizer in an essentially tensionless state without intermediate texturized yarn accumulation.
