Abstract
A double twist thread twisting frame having a plurality of double twist spindles thereon each of which is surrounded by a balloon limiter having an upper rim thereon and at their lower parts a storage disc and a whorl driven by a belt spaced below the storage disc. A closure structure is provided around each balloon limiter to define a channel which communicates with the spindles and the interior of the balloon limiters. A suction device is connected in circuit with the channel means to evacuate the air contained therein. The closure structure, particularly an upper wall thereof, is located generally at the level of the upper rim of the balloon limiter and has a circular opening coaxial with the upper rim of the balloon limiter. The circular opening is somewhat smaller in diameter than the upper part of the balloon limiter. A suction opening is provided in the balloon limiter below the upper wall of the closure structure and a blower nozzle is connected to a tube which extends in the longitudinal direction of the frame for supplying conditioned air to the circular opening in the balloon limiter.
