Abstract
A yarn winding machine is equipped with transducer means (39) disposed in the area of the ends (33, 35) of the contact roll shaft (37) to monitor the pressing force of the contact roll (11) against the yarn package (9) being wound. The short paths between the sensors and the areas where the contact roll presses against the surface of the yarn path makes it possible to measure the downward pressure at the individual measurement points or as a whole. The signals can be used to control the pressing force and also to maintain the parallelism of the axes (A, B) of the spool mandrel (5) and of the contact roll (11).
