Stator section for a spindle, more especially a two-for-one spinning or twisting spindle

Abstract

There is described a stator section, for a spindle which has a spindle rotor at least partly enclosing the stator section, wherein the stator section incorporates, in the region occupied by surfaces situated opposite the spindle rotor, a dust and thread catching means. To provide this means, parts of surfaces of the stator lying opposite the rotor may be roughened. For this purpose the stator may be provided with grooves having mechanically-roughened surfaces or may have wound around it a strip of Velcro or strip of some other material, whereby the foreign bodies which are carried by the air, which flows through the rotor on the counter-current principle, collect on the said roughened parts of the surface of the stator or on said strip, as a result of which the foreign bodies are prevented from reaching the region occupied by a spindle bearing arrangement. In the arrangement shown, a thread package carrier 7 of the stator section of a two-for-one twisting spindle has dust and thread catching means in the form of circumferential grooves 14 having surfaces of increased roughness.
