Automatic taker-in for double-twisting spindles and double-twisting spindle equipped with said taker-in

摘要

The invention provides an injentor (39) having a suitably formed head (32) which can partially penetrate through a lateral aperture in a spindle (10) into the vicinity of chamber (27) containing the expansible olive (16).;Penetrating into chamber (27), said injector (31) laterally displaces the olive (16) and by injecting through the beak (33) a fluid under pressure creates in the axial passage a negative-positive pressure necessary for trasporting the filament (17).;In the vicinity of chamber (27) there can advantageously be provided a mobile section (28) which is circumferentially displaceable by means (42) which is included on the head (32) of injector (31), when said injector (31) penetrates or is pene- tratingthe spindle (10).;The injector (31) is further provided with an arm (38) which may be pivoted in the vicinity of the balloon container (19) or on an auxiliary bench (40).
