| 摘要 |
The present invention relates to a method for monitoring the operation of an insertion brake (6) suitable for being used between a yarn preparing device (4) and a loom (R), comprising a movable brake element (21) which is movable between a position of rest on one side of the yarn (1) and a braking position on the other side of the yarn (1), wherein the brake element (21) is coupled to an electric driving motor (23) via a shaft (22), wherein the acceleration of the shaft (22) and the parts connected thereto is determined with every stroke of the brake element (21), and if the measured value is higher than or lower than a specified value, a signal indicating this will be generated. <IMAGE> |
