Abstract:
Rotary twister element suitable to keep under tension the fibres during the twisting operation in a frictional open-end spinning process, constituted by a solid, hollow, reduced-thickness element (5) with perforated skirt (4), which is internally provided with a suction duct (7) defining a longitudinal slot (6), the edge of which, which constitutes the thread formation line, is suitably inclined relatively to the generatrix of the same solid, hollow element, as a function of the direction of rotation of the solid element, and of the direction of thread extraction. Also a screen (21) is provided for the air dragged by the rotation of the solid element, which may have a cylindrical shape, a cone frustum shape, or the shape of any other revolution solid.
