摘要

The invention relates to a yarn (2) twist retention (1) on an open-end spinning machine comprising a part of a wall of a bent yarn (2) delivery channel (5) forming the inner side (501) of the bent section (50) of the bent yarn (2) delivery channel (5), this section of the wall of the bent yarn (2) delivery channel (5) on the yarn (2) twist retention member being provided with at least one yarn (2) twist retaining means. The yarn (2) twist retention means is made as a longitudinal groove (8) in a part of the wall of the bent yarn (2) delivery channel (5) forming the inner side (501) of the bent section (50) of the bent yarn (2) delivery channel (5), the walls (80) of the longitudinal groove (8) being situated symmetrically to each other along the longitudinal symmetry plane of the bent section (50) of the bent yarn (2) delivery channel (5). <IMAGE>
