Abstract
A yarn-winding assembly mounted on a support is provided with a motorized spool and with an oblique spacing pin, between which a yarn is wound. The spacing pin is supported so that it can rotate about an axis of the motorized spool by unidirectional rotary support elements. The spacing pin rotates freely with respect to the spool when the latter rotates in the yarn unwinding direction and the former is retained from rotating by stop elements, and is instead integral with the spool when the spool rotates in the opposite yarn rewinding direction.
Claims10
A yarn feeder comprising:
- a yarn-winding assembly mounted on a support and provided with a motorized spool and an oblique spacing pin, between which a yarn is adapted to be wound, wherein said spacing pin is supported so that said spacing pin can rotate about an axis of said motorized spool by unidirectional rotary support means, which are adapted to allow the free rotation of the spacing pin with respect to the spool when the spool rotates in the yarn unwinding direction, the spacing pin being retained from rotating by stop means, and to block the rotation of the spacing pin with respect to the spool when the spool rotates in the opposite yarn rewinding direction.
