ABSTRACT:
Improvements are made in a weft yarn drawing and measuring device for a weaving loom in which a weft yarn to be picked into a shed of the loom is drawn off to a predetermined length by means of measuring and pressing rollers driven for rotation about horizontal axis. The pressing roller is constantly driven at a circumferential speed equal to the circumferential speed of rotation of the measuring roller and is movable between a position disengaged from the measuring roller for allowing the leading end of the weft yarn to rest on the measuring roller and a position in rolling contact with the measuring roller for drawing off the yarn gripped between the two rollers. The device is characterized by self-adjustable torque transmission means capable of transmitting a driving torque to the pressing roller and having an allowance for the movement of the pressing roller between the two relative positions thereof to the measuring roller.
