Method and device for metering a predetermined length of weft yarn on shuttleless looms

摘要

The invention relates to a method and a device for metering predetermined lengths of weft yarn on shuttleless looms. A distributor wheel executes a rotational movement continuously in conjunction with the hollow shaft of the device for preparing the weft yarn. At least one complete insertion length of the weft yarn is respectively displaced along the storage drum, which consists of segments, in the direction of the draw-off of the weft yarn in the interspace between two claws of the distributor wheel. This insertion length is held by the guide element in the interspace between the claws of the distributor wheel and is released at the time of insertion of the weft yarn into the shed.
