ABSTRACT:
A weft predelivery and measuring device for a shuttleless loom and particularly for such a loom with a lateral weft reserve and weft insertion by means of a pneumatic or hydraulic fluid has a tubular member integral with a rotary shaft through which an axial channel passes, facilitating the passage of the weft yarn into a tubular member for winding around a drum of adjustable peripheral dimensions. This drum is prevented from rotating by means of permanent magnets. In order to retain a predetermined number of turns of weft yarn around the drum and in order to release these turns periodically, a wheel is provided which on its periphery has equi-angularly spaced claws and which is supported by a spindle continuously rotatable by a worm and a worm gear driven from the rotary shaft.
