ABSTRACT:
A device for weft tensioning adjustment in weaving looms of the type having continuous weft feed, to be applied at the side of the loom. The device comprises - mounted on a single support - a pair of elastic resilient laminae, biased into mutual contact with an adjustable pressure knob and arranged in the path of the weft thread being supplied, for engaging said thread between them and providing for the braking thereof, and an oscillating lever ending with a threadguide, through which eye is passed the weft thread, after engagement between said laminae and before reaching carrying members, said oscillating lever being adjustably urged by spring means to move away from said laminae and from said members, in order to take up slack in said weft thread when it exists.
