ABSTRACT:
A textile machine for forming yarn windings of any shape comprising a frame, a feed of yarn to be treated, a support element, provided with a motor for its rotation, for collecting and winding treated yarn, a thread guide for distributing the yarn along the support element, at least one roller, provided with a motor for its rotation, which receives yarn from the yarn feed and feeds it to the collecting support element via the thread guide, and a sensor positioned between the at least one roller and the support element for collecting the treated yarn, in which machine the sensor senses the braking force generated by the at least one roller on the yarn being wound on the support element, and is connected to a processor which compares the measured braking force with a preset force, and varies the rotational speed of the motor of the at least one roller to adjust the previously measured braking force to the preset value by increasing the rotational speed of the roller if the measured braking force is greater than the preset value, and decreasing the rotational speed of the roller if the measured braking force is less than the preset value.
