Abstract
The thread feeding device has a supporting element for a spool of thread to be fed, and a variable-speed motor having a body connected to the supporting element and an output shaft connected to an arm that is rotatable about the axis of the spool with respect to the spool itself. The arm is provided, proximate to its end that is spaced from the spool axis, with a thread passage so as to perform, as a consequence of its own rotation, the gradual unwinding of the thread from the spool. The device also has an actuation and control element that drives the motor with a speed that can vary according to the tension required for the thread during feeding.
