Abstract

The yarn (31) is fed substantially tangentially from a feed station (30) to the feed end (101) of an accumulator roller (10) of a yarn accumulator (1), drivable by a rotary drive means (120). The yarn is dischargeable from an exit end (103) of this accumulator roller (10) counter to the action of a restraining element (14) through a yarn guide means (4) arranged in prolongation of the axis (122) of the accumulator roller. The restraining element (14) is of radially outwardly open construction and is formed by a yarn restraining ring drivable relative to the accumulator roller (10). The ring includes a radially outwardly open yarn restrainer (141). The yarn guide means (4) consists of two mutually separable yarn guide components (40, 41) and is constructed as a yarn conveyor which deflects the yarn (31) out of a prescribed yarn path (32) into a yarn path intersecting the path of the revolving yarn restrainer (141). In order to measure the yarn length accumulated on the accumulator roller (10), the yarn-revolution monitoring-device (50) and a device (23) to determine the yarn rotation direction are associated with the accumulator roller (10), both of which are associated for control …
