| 摘要 |
<p>The invention concerns a device for winding, at high speed, a yarn on a support driven in rotation and comprising a thread dispensing system (5, 6) displaced in a reciprocating movement parallel to the surface of said support with fast deceleration and acceleration at the changeover point of the reciprocating movement. The invention is characterised in that the displacement of the depositing yarn guide (6) is operated via a mobile element or cursor (5) associated with a magnetized plate (1) of a linear motor, powered with two-phase or three-phase current, and wherein the stator consists of at least an assembly of elementary modules either facing one another or in the extension of one another, comprising each a plurality of C-shaped magnetic circuits (4) defining between the ends of their spaced apart branches an air gap wherein is positioned the magnetized plate (1), including alternating North and South poles (N and S) which constitutes the mobile element displacing the cursor (5) bearing the yarn guide (6).</p> |
