Abstract
A device for winding, at high speed, a yarn onto a rotating support comprises a yarn delivery system, displaced so as to undergo a to-and-fro movement parallel to the surface of said support with rapid deceleration and acceleration at the point of reversal of the to-and-fro movement. A depositing yarn guide of the delivery system is displaced by means of a moving element or cursor associated with a magnetized plate of a linear motor, supplied with two-phase or three-phase current. The stator is formed by at least one assembly of elementary modules placed either face to face or placed so that each lies in the extension of another, each having a plurality of C-shaped magnetic circuits that define, between the ends of their separated legs, an airgap inside which the magnetized plate is positioned, comprising an alternation of North and South poles (N and S), which constitutes the moving element that displaces the cursor carrying the yarn guide.
