Abstract (en)
A device for the tapering of yarn-gathering bobbins on a twisting frame comprises a traversing roller (11) which is actuated by the main motor of the twisting frame by means of appropriate mechanisms and is provided with a Z-shaped profile (12) generating a reciprocating motion in a connecting road (14) and where the law governing tapering of the bobbins is controlled by an inclinable tapering guide (19), which is kinematically connected to the aforesaid connecting road (14) and is able to vary the stroke of the reciprocating motion of the connecting road (14). If the said device, the inclination of the tapering guide (19) is adjusted by means of the operation of a pneumatic actuator (21), where each stroke of the pneumatic actuator (21) enables practically instantaneous variations in tapering having a pre-set value to be obtained. <IMAGE>
