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.
