ABSTRACT:
A two-for-one twisting spindle for threading a thread by compressed air is comprised of a hollow axle with two cylindrical chambers. A thread storage disk with a thread guiding channel is connected to a lower end of the hollow axle, and a thread inlet tube is connected to the upper end. A thread brake comprising a braking cartridge, an upper and a lower braking ring, and a support is arranged inside the first cylindrical chamber. The braking cartridge, in a braking position, rests with an upper end at the upper and with a lower end at the lower braking ring. In a released position, the braking cartridge rests at the support. The lower braking ring is connected to a hollow piston slidable inside the first cylindrical chamber. A jet of compressed air generates a suction effect in the hollow axle and forces the thread from the thread inlet tube through the thread guiding channel. The hollow piston is axially displaceable by the suction effect, thereby releasing the braking cartridge from the braking position and opening a path for the thread through the braking rings. A tube extending as a downward projection of the lower braking ring and guided within the first cylindrical chamber has a lateral opening for communicating with the first cylindrical chamber. A second hollow piston is connected to the free end of the tube and is slidable inside the second cylindrical chamber.
