Device for flexible retention of a floating system for the advancement of turns of yarn reserve in weft feeders for weaving looms

摘要

A device (20) for retention of a floating system (13) for the advancement of turns of yarn reserve in weft feeders (10) for weaving looms; comprising a plurality of cylindrical stop elements, each of which comprises a metal coupling pivot (21) and a cylindrical bush (22) made of soft rubber, wherein the bush (22) is provided with at least one perimetric groove (23) which accommodates and retains a continuous ring (24) made of plastics which protrudes radially beyond the cylindrical surface of the bush in order to make contact with the floating system so as to provide rotational retention of the floating system. <IMAGE>
