US 6,199,787 B1 · Method of transferring individual ends of yarns from a beam to individual cones

Abstract

A method of winding yarn into hanks, comprising the steps of loading a beam having a sheet of parallel ends of yarn wound thereon onto a rotatable beam stand; unwinding the sheet from the beam and passing the sheet through a nip between two reciprocating rolls; separating the parallel ends of yarn in the sheet from each other; and guiding each of the separated ends of yarn to a rotatable reel. The ends of yarn are then wound onto the rotatable reel by rotating the beam to release the sheet wound thereon; rotating the interacting rolls to draw the sheet through the nip; and rotating the reel to wind each separated end of yarn onto the reel. The rotational velocity of the beam and of the reciprocating rolls are controlled so as to keep the tension on the sheet of yarns below a defined value. By controlling tension, one reduces the likelihood of thread breakage and causes the yarns to be wound onto the reels in the form of loose hanks. The yarn may be easily unwound from the loose hanks and wound into cones for knitting and weaving.

Dependent claims

A method of winding yarn into hanks, comprising the steps of:

a) loading at least one beam having a sheet of substantially parallel individual ends of yarn wound thereon onto a first rotatable beam stand;
b) unwinding an end of the sheet of ends of yarn from the beam and passing the sheet through a nip between two interacting rolls;
c) separating the parallel ends of yarn in the sheet from each other;
d) guiding each of the separated ends of yarn to an elongated rotatable reel, with the proviso that each end of yarn is guided to a different point along the length of the reel;
e) winding the ends of yarn onto the rotatable reel by rotating the beam to release the sheet of ends of yarn wound thereon at a first rotational velocity;
rotating the interacting rolls to draw the sheet of ends of yarn through the nip at a second rotational velocity;
and rotating the reel to wind each separated end of yarn onto the reel at a third rotational velocity;
and
f) controlling the first rotational velocity to prevent sudden changes in a tension applied to the sheet of ends of yarn, and controlling the second rotational velocity to prevent sudden changes in a tension applied to each separated end of yarn.
