US 6,637,695 B2 · Method of winding a traveling yarn at a work station of a spinning bobbin winding machine or of a bobbin winding machine

Abstract

A method of winding the yarn traveling at a work station of a spinning bobbin winding machine or of a bobbin winding machine from a yarn source onto a take-up bobbin (4). After each yarn interruption, the yarn end is unwound from the take-up bobbin (4), a yarn joinder reconnects the yarn source and the take-up bobbin (4) and the winding process is then continued if a tolerable yarn joining location is present. Upon the occurrence of each yarn interruption, the amount of yarn wound since the last yarn joinder is determined. If such amount of yarn is determined to be less than a predetermined amount of yarn, a sufficient amount of yarn is unwound and separated from the take-up bobbin (4) to include the last-occurring yarn joining location in the separated yarn section. This results in an optical improvement in the quality of the finished textile product.

Dependent claims

A method of winding a yarn traveling at a work station of a yarn winding machine from a yarn source to a take-up bobbin onto which the yarn is wound, comprising the steps of:

a minimum criterion is predetermined for an amount of yarn to be wound onto the take-up bobbin between successive yarn joinders,
after a yarn interruption, an amount is determined for the yarn wound onto the take-up bobbin since a preceding yarn joinder,
after the yarn interruption, a yarn end from the take-up bobbin is unwound therefrom,
if the amount determined for the yarn wound onto the take-up bobbin since the preceding yarn joinder is less than the amount of the predetermined criterion, the length of yarn unwound from the take-up bobbin is sufficient to include the preceding yarn joinder and the unwound length of yarn is separated and removed,
a yarn joinder is formed between a yarn end from the yarn source and the yarn end from the take-up bobbin, and
winding of the yarn from the yarn source onto the take-up bobbin is then continued.
