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 with an impulse counter (5). This impulse counter (5) is switchable from forward counting to backward counting or vice versa as a function of a change in the yarn rotation direction.
