<p>A textile machine for forming yarn windings (36) of any shape comprising a frame, a feed of yarn to be treated, a support element (20), provided with a motor (21) for its rotation, for collecting and winding treated yarn, a thread guide (35) for distributing the yarn (14) along the support element (20), at least one roller (12,13), provided with a motor (16,17) for its rotation, which receives yarn from the yarn feed and feeds it to the collecting support element (20) via the thread guide (35) , and a sensor (24) positioned between the at least one roller (12,13) and the support element (20) for collecting the treated yarn (14), in which machine the sensor (24) senses the braking force generated by the at least one roller (12,13) on the yarn being wound on the support element (20), and is connected to a processor (25) which compares the measured braking force with a preset force, and varies the rotational speed of the motor (16,17) of the at least one roller (12,13) to adjust the previously measured braking force to the preset value by increasing the rotational speed of the roller (12,13) if the measured braking force is greater than the preset value, and decreasing the rotational speed of the roller (12,13) if the measured braking force is less than the preset value. <IMAGE></p> |
