ABSTRACT:
In a weft feeder for weaving looms, a rotating arm winds a reserve of weft yarn turns around a drum held stationary and structure is provided to move forward the turns on the drum, keeping them mutually spaced. The structure comprises a set of columns, prevented from rotating in respect of said drum, but partially and variably emerging from seats in its periphery, thanks to the motion imparted thereto by the feeder motor shaft, in respect of which they are rotatably mounted by way of a skew bushing and a rotary bearing. This bushing is formed of two hollow bodies, the first of which is keyed to the motor shaft, eccentric in respect of the drum axis, while the second is rotatably mounted on the first, but adopted to be locked thereto in two positions at 180.degree. one in respect of the other and having its outer surface inclined in respect of that axis.
