Abstract

A two-for-one twisting spindle has a compressed-air-actuating device which is disposed in the region of the hollow axle (21) of the spindle (1) above the spindle rotor, and which influences the run of the yarn and to which a compressed-air passage (29), extending through a stationary part (7) of the spindle, leads, in order to prevent the yarn from being drawn through the hollow axle of the spindle in the event of breakage of the yarn. The compressed-air-actuated device is a compressed-air-cylinder (27) whose axis intersects the hollow axle of the spindle at right angles thereto and whose outer wall has two openings (25) which are located diametrically opposite one another and which are in alignment with the hollow axle of the spindle, and a piston (26) which is displaceable within the compressed-air cylinder and whose rear end is subjectable to compressed air for the purpose of clamping (FIG. 1), or cutting (FIG. 5) through the yarn.
