A threading device for double twist thread twisting frames which have a spindle and a suction device movable toward a storage disc on the frame. A service carriage is movably mounted on the frame along one side thereof. A threading head is movably mounted on the service carriage and is movable between a rest position remote from the spindle and a threading position in which it is in registry with the upper end of the spindle. The threading head has on its side facing the spindle axis an inlet slot that extends parallel to the spindle axis. A thread channel is provided adjacent the bottom of the inlet slot and, in the threading position of the threading head, is in registry with the spindle axis. At least two holder elements are mounted on the frame and are spaced one above the other and substantially in the plane of movements of the inlet slot on the threading head. A piece of thread extends between the two holder elements and presents same to the threading head upon movement thereof toward the threading position.

Threading device for double twist thread twisting frames

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.
