ABSTRACT:
An improved weft yarn control for shuttleless looms in which, as the loom reed beats the inserted weft yarn toward the fabric fell, the trailing portion of the weft yarn is caused to first move forwardly and upwardly into engagement with a stationary clamping device operated in accordance with a prescribed timed sequence. As the trailing weft yarn portion continues its forward movement, it engages a stationary yarn severing device which severs the trailing weft yarn portion from the inserted portion at or near the edge of the fabric fell. The severed trailing portion is then maintained in the path of the yarn insertion device as it moves inwardly on its next pick, whereupon it is seated therein and the timed clamping device released.
