The yarn twister (6) for the yarn (4), at an open-end spinner, has an entry ring (8) to take the yarn (4) from the outlet section (3). Its opening (80) is located in front of the entry opening (70) of the curved yarn takeoff channel (7). The upper part of the rear side of the entry ring (8) circumference passes into the yarn twister (6). The remainder of the rear side lies on the leading side of the holder (5) for the yarn twister. The entry ring (8) is positioned with at least part of its length in the outlet section (301) of the takeoff channel (30) in the outlet section (3). The holder (5), for the yarn twister (6), has a stepped opening (53) at its upper section, with a larger diameter opening out of the holder (5), and its smaller diameter coupled to the curved takeoff channel (7), which also takes the entry of the yarn takeoff tube (9). A rubber ring (10) is round the takeoff tube (9), to fit into the larger diameter of the stepped opening (53). The outer diameter of the ring (10) is larger than the inner diameter of the bigger section of the opening (53), and its inner diameter is smaller than the outer diameter of the takeoff tube (9). The trailing side of the holder (5) has a laying surface (54) for the end of a pressure screw bolt (11), with adjustment in the wall of the spinner body (1), at the rear of the holder (5) for the yarn twister (6).
