Method for producing an effect yarn on an open-end rotor spinning machine, and corresponding effect yarn

摘要

The aim of the invention is to produce an effect yarn on an open-end rotor spinning machine, formed from an alternating line-up of yarn sections and effects consisting of pre-determined thickenings. To this end, an effect is produced where the yarn is joined by means of a piercing end, in the piercing region of the yarn located downstream of the piercing end, following a break in the thread. The invention enables the quality of the yarn produced in this way to be improved such that unwanted deviations from the pre-determined repeat of pattern of the effect yarn, caused by piercing regions, are eliminated.
