Device for winding a yarn on a holder driven in rotation

A device for winding a yarn on a holder driven in rotation, the yarn being dispensed by a yarn guide displaceable in translational motion parallel to generatrices of the holder driven in rotation, comprising:

• a carriage receiving the yarn guide and having arrangements for coupling to a transmission and flexible drive member mounted between two return elements and capable of imparting a reciprocating movement to said yarn guide, in combination with means for guidance in translational motion parallel to the generatrices of the rotary holder, the yarn guide, the guidance means and the coupling arrangements being offset angularly on the carriage according to three vertices of a triangle, the means for guidance in translational motion being arranged between the yarn guide and the coupling arrangements, and serving as a tilting axis for said carriage in order to generate an additional speed component in a vicinity of reversal points under effect of tilting of said carriage about said axis during passage of said coupling arrangements from one side of the elements to another, and the guidance means being separated from the yarn guide and from the coupling arrangements at distances which are determined so as to speed up reversal times at said yarn guide.
