ABSTRACT:
A device for separating reserve turns of thread on a weft feeder drum comprising a swift that is formed by a set of axial rods that partially and variably protrude from respective slots formed on the drum of the feeder by virtue of the compound motion applied to the swift by a bush that is associated with the drive shaft. The bush is supported by a recessed coaxial portion of the drive shaft, and a diametrical pin is provided which is arranged so as to cross said shaft and said bush, and to bring about a pivotal engagement between said shaft and said bush. The bush has a cylindrical and eccentric outer surface and an internal surface that is profiled so as to form two portions of truncated-cone surfaces. The bush can thus oscillate about the pin and be arranged at an angle with respect to the drive shaft. An actuation element is provided to vary the inclination of the bush when the bush is rotated with respect to the element, which is kept fixed by a pushbutton stop device.
