Abstract
A yarn throwing and twisting machine has at each of a number of working positions two or more throwing spindles, a twisting spindle, a manually disengageable yarn feeder, and yarn break detectors. Pneumatic jacks are provided to disengage the spindles and feeder upon yarn breakage and are controlled by air supplied through a solenoid valve responsive to the yarn break detectors and by a manually operable valve between the throwing and twisting spindles. The solenoid valve is closed, however, upon manually disengagement of the yarn feeder for the purpose of allowing starting up at an individual working position after yarn breakage.
