Method and apparatus of transferring yarns from a beam to individual cones

摘要

A method and apparatus of winding yarn (6a) into hanks (19), including the steps of loading a beam (1) having a sheet of parallel ends of yarn (6a) wound thereon onto a rotatable beam stand (9); unwinding the sheet (6) through a nip between two reciprocating rolls (8); separating the parallel ends of yarn in the sheet (6) from each other; and guiding each of the separated ends of yarn to a rotatable reel (17). The ends of yarn (6a) are then wound onto the rotatable reel (17) by rotating the beam (1) to release the sheet wound thereon; rotating the interacting rolls (8) to draw the sheet through the nip; and rotating the reel to wind each separated end of yarn onto the reel (17). The rotational velocity of the beam (1) and of the reciprocating rolls are controlled so as to keep the tension on the sheet (6) of yarns below a defined value. By controlling tension, one reduces the likelihood of the thread breakage and causes the yarn (6a) to be wound onto the reels in the form of loose hanks. The yarn may be easily unwound from the loose hanks (19) and wound into cones for knitting and weaving.
