Abstract (en)
A weft feeder device with swift-like drum (14) , for fluid-jet weaving looms, wherein the hub (20) of the drum has a frustum-shaped adjustment element (25) on which the pad-like ends (35) of the spokes (36) of the swift, which have a corresponding and complementary taper, rest with an elastic contact. The adjustment element is axially guided and movable and has a threaded axial seat with which an internally threaded shaft (27) cooperates. The internally threaded shaft is actuated from the outside and produces axial movements of the element and corresponding radial movements of the spokes in order to vary the polygonal perimeter of the swift.
