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.
