Weft yarn feed unit, for a jet loom, has neighboring stop tines at the yarn store body to give a controlled take-off in measured lengths in a trouble-free intermittent control action

摘要

The weft yarn feed unit (F) for a loom, to deliver measured weft lengths, has a stop tine (S1) with a radial and axial movement in relation to the axis (X) of the yarn store body (K), to give a weft yarn length measurement function and end the yarn take-off.. A second stop tine (S2) has a regular radial movement in relation to the yarn store body between a weft grip position and a passive setting for the yarn take-off, and to take the measured length from the first stop tine.. The stop tines are next to each other, with an offset in the axial and/or peripheral direction of the yarn store body.
