Abstract
A method for producing 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, wherein an effect is produced where the yarn is joined by means of a piecing end, in the piecing region of the yarn located downstream of the piecing end, following a break in the thread. The quality of the yarn produced in this way is improved such that unwanted deviations from the pre-determined repeat of pattern of the effect yarn, caused by piecing regions, are eliminated.
