Abstract
Weft measuring device for weaving looms, and in particular for shuttleless looms where the weft is cast through a shed by a pressurized mechanism or by the energy communicated to the mass of the yarn by a casting mechanism. The device has a pair of propelling rollers driven in rotation which form a gripping line between which the weft yarn is introduced intermittently by way of elements actuated in relation to the weft casting program. At least one of the rollers has a structure such that the end of the gripping line toward which the yarn is conveyed at the start of measurement moves regularly and synchronously with the cycle of the loom.
