Abstract: 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.
