    • The metering device for metering the weft yarn of a loom comprises a metering roller which is disposed between a supply unit and a draw off unit and which, in metering operation, is wrapped around by the weft yarn and determines the weft yarn draw off speed. In the event of a weft yarn break, a new waft start is injected past the metering roller into a catching nozzle and by way of a deflector into a yarn accumulator. A brake terminates the injection step. While a draw off element applies tension to the yarn, the yarn is wrapped automatically and in a number of turns around the metering roller by being moved into a catching zone of a catcher, which is rotatable around the metering roller axis, through the agency of a relative movement between the injected weft yarn and the catcher. During one revolution of the catcher around the roller axis, the weft yarn is deposited on the metering roller in the form of a wrapping. After a number of wraps of weft yarn around the metering roller, a severing element parts off the remainder of the yarn moving towards the accumulator and the resulting new yarn tip is moved by the metering roller into a start position for the weaving cycle.
    • 用于计量织机纬纱的计量装置包括计量辊,其设置在供应单元和抽出单元之间,并且在计量操作中,由纬纱缠绕并确定纬纱牵引速度。 在纬纱断裂的情况下,将新的液压起动通过计量辊注入捕捉喷嘴,并通过偏转器注入纱线收集器。 制动器终止注射步骤。 当牵引元件对纱线施加张力时,纱线通过被移动到可以围绕计量辊轴线旋转的捕集器的捕获区域中而被自动地缠绕在计量辊周围的数圈内,通过代理 注射纬纱和捕手之间的相对运动。 在围绕辊子轴线的捕集器一圈之间,纬纱以包裹的形式沉积在计量辊上。 在计量辊周围缠绕了多条纬纱之后,切断元件将纱线的剩余部分分离,朝向蓄能器移动,所得到的新纱线尖端由计量辊移动到编织周期的起始位置。
