Abstract
A reel-stick arm for winding yarn with regulated pressure between the reel and its actuation roller, particularly for double-twist twisting frames, comprising automatic means for balancing the effect of weight variation of the reel being formed, means for automatic raising of the reel-stick arm, and automatic means for clamping the arm in the raised position, said raising and clamping means being co-ordinated by interlocking means.
Claims8
A reel-stick arm for winding yarn at an adjusted pressure between the reel (16) and its driving roller (19) rotating at a constant linear speed, particularly for use in double-twist twisting frames, comprising counter-weighting means (35) which counterbalance the effect of the variation in weight of the reel of yarn being formed, characterized in that it comprises means (50) for automatic raising of the reel-stick arm and automatic clamping means (59) for temporary blocking of the reel-stick arm in the raised position, said lifting-up means (50) and said clamping means (59) being co-ordinated together by interlocking means.
