ABSTRACT:
A multiple spindle spinning frame has a plurality of tapered rotatable spindles carrying bobbins upon which fiber is wound, and each spindle has a disc below the bobbin which is movable axially with respect to the spindle. Below each bobbin is a vertically reciprocable plunger, the top end of which abuts against the underside of the disc to raise the bobbin from the spindle. The plungers are connected to a common bar, that is raised and lowered by one arm of a double-arm lever, the other arm of which is connected to a reciprocable bar, one end of which is connected to a pivoted lever arm. Also connected to the lever arm is a flexible tension member which is wound onto a winding reel driven by a reversible electric motor. A pivoted lever arm has one end that rides on the windings that are wound onto the winding reel, while the other end engages a first limit switch to shut off the motor when the windings have built up on the winding reel as the bobbins are ejected. A second limit switch is engageable by the first-named lever arm as the latter reaches the end of its travel during reverse operation of the motor, so as to shut off the motor as the first-named lever arm reaches its initial position.
