ABSTRACT:
In a textile yarn processing machine, such as spinning and twisting machines, the combination therewith of control apparatus for automating movements of various elements of the yarn processing machine for preparing the same for doffing of full packages and for starting-up of new packages of processed yarn including combinations and subcombinations of the following. Independent hydraulic fluid operated devices are connected to the builder motion mechanisms of the machine including a piston and cylinder device positively connected between the crank arm of the builder motion mechanisms and the machine frame for relative reciprocating movement with respect to each other during reciprocating movements of the crank arm and the ring rail of the machine. The fluid operated devices cooperate with the builder motion mechanisms for lowering the ring rail to a doffing position, assisting the ring rail to raise under the influence of the builder motion mechanisms to a yarn processing position by at least controlling the speed of raising of the ring rail, and lowering and jogging the ring rail up and down adjacent the bottom of the bobbins on the spindles for removing slack and for bunch or wrap building of the yarn during start-up. An electrical circuit control is connected with the fluid operated devices for being actuated to control the fluid operated devices through the operating sequences. A solenoid operated latch member, hydraulically operated yarn guides and a builder motion rewind mechanism may be included and controlled by the positioning of the ring rail in desired positions and through the electrical circuit control.
