<p>A bobbin doffing mechanism for spinning and twisting frames is disclosed, the improvement consisting in that a plurality of fluid-controlled doffing units is mounted on a generally elliptical race so that the spindle line is arranged along a rectilinear path of the race, the opposite rectilinear path being opposite to the spindle line. The plurality of doffing units travel in a closed loop on the generally elliptical path. The doffing units comprise gripping members for doffing and discharging the bobbins, these units being fluid-controlled, preferably pneumatically controlled, the sequence of operations being commanded by a specially provided cam mechanism.</p> |
