ABSTRACT:
The invention relates to an accumulating device for weft yarn feeders to textile machines, capable of positioning windings of weft yarns onto a fixed winding drum and of advancing them by keeping the same spaced between each other. It essentially comprises a series of non rotating fingers housed in suitable openings of the drum peripheral skirt, which partially and variably protrude from said skirt as a consequence of the motor shaft movement forming said windings and to which said fingers are coupled through a bearing and a rotary eccentric bush. In order to allow to vary at will the step between said windings, the bush is mounted on said shaft with the interposition of a ball joint so that its inclination with respect to the shaft axis can be adjusted at will.
