ABSTRACT OF THE DISCLOSURE Thermoplastic yarn is texturized by the known method of forwarding it in a heated condition to a crimping zone at the entrance of a stuffer chamber so as to form a plug of crimped yarn within the chamber and withdrawing the yarn from the other end of the plug at a speed which is related to the input speed. The improvement comprises deriving signals from the speed of the yarn plug in the stuffer chamber, the resultant signals being used to control the temperature of the yarn passing to the crimping zone in such a way as to maintain the speed and hence the quality of the bulk yarn substantially constant.
