Winding

WINDING

The operation of transferring yarn from one form of package to another, such as winding from hanks to bobbins, from bobbins to cones, from cops to bobbins, etc. The process that follows spinning determines whether winding is necessary or not. Cops and ring tubes or bobbins can be used in that form as weft in the shuttle, but they are not suitable for making into warps, nor as supply to knitting or braiding machines. Yarn in the other forms of spun packages requires to be pirned for use as weft. Although yarn winding is not a fundamental process like spinning and weaving, it occupies a very important place in the economics of yarn processing, and probably embraces a wider range of different machines than any other phase of textile processing. Even a bare catalogue of the different kinds of winding machines would far too lengthy for inclusion here. Broadly, winding machines are adapted for: - 1. Winding yarn for use as weft in loom shuttles, including winding on to wood pirns and paper tubes; solid cops for use in shuttles without tongues; quills for use in ribbon and smallware looms; layer locking at the nose of the pirn to prevent sloughing of rayon weft; bunch building at the base of pirns for use in automatic looms; weft rewound from spinner's cops into larger packages to give maximum length at one filling of the shuttle. The yarn supply can be from hanks, cops, spinner's bobbins, cones, cheeses, warps, etc. 2. Winding yarns for making warps from spinner's cops or bobbins, hanks that have been sized, bleached or dyed, cones, cheeses, and other forms of supply. 3. Winding yarns into suitable form for sizing, bleaching, dyeing, or for receiving other wet treatments, including hanks, warps, cheeses, cops, etc. 4. Winding yarns for knitting, i.e., on to splicer bobbins, cones, pineapple cones, bottle bobbins, etc., and on to bobbins for use in braiding machines. 5. Special process winding such as the precision winding of several threads side by side in tape form for covering wire, etc. 6. Winding yarns into packages for retail selling such as winding mending wools on cards; sewing thread on wood spools or small flangeless cheeses; crochet embroidery and other threads into balls; packing string info balls and cheeses; harvesting twine into large balls and cones, etc.
