Winding and Package Building in Rotor Spinning
topic
Rotor spinning directly winds yarn onto cross-wound conical or cylindrical packages of 2 to 4 kilogram mass using individual unit winding drums with electronic precision winding systems that control traverse ratio and winding angle to produce ribbon-free packages with uniform yarn layering and defined package density suitable for direct warping, weaving, or knitting without rewinding.
Role
Eliminates the separate winding stage required after ring spinning by producing directly usable cross-wound packages on the spinning machine, reducing the processing stages and associated yarn damage and quality risk between spinning and weaving or knitting, with package quality including winding tension consistency and ribbon-free layering directly determining warping and weaving performance.
