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).
