Abstract: In a device for manufacturing covered yarn in which one or several threads (6) surround a yarn core in a helical fashion a rotating winding spindle is provided with a spool (5). The winding thread (6) is located on the spool (5). The winding spindle is surrounded by a stationary pot (8, 8a, 8b) that can be divided along a geneatrix, in particular in the axial direction of the pot (8, 8a, 8b). The parts of the pot (8, 8a, 8b) comprise a layer (30, 30a, 30b) that surrounds the spool (5) at least partially and is mechanically and/or thermally wear-resistant and/or exhibits low friction.

Abstract: A bobbin adapter for a holding device for high speed rotating yarn bobbins includes a hollow cylindrically-shaped body, a spindle disposed in a central bore of the body, and at least one catch member moveable transversely of the spindle axis. The adapter is provided with a guide member on the body cylindrical wall which is moveable to engage the catch member and impart movements to the catch member toward and from the body axis. The catch member is a sliding tab mounted for movement crosswise of the body axis and is provided with a central bore disposed in part coincident with the body central bore.

Abstract: A mount for spinning spindles which discloses various embodiments of wedge type clamping devices for clamping a sleeve, which is disposed around the spindle housing, securely to a spindle bearing plate. The sleeve surrounds the spindle housing with vibration damping elements between them. The wedge clamping devices are driven by a threaded nut which is tightened up around the sleeve and this clamps the sleeve to the plate. A device for separating the drive belt from the drive whorl of the spindle is attachable on the sleeve and presses the belt off the drive whorl, freeing the spindle so that it may then be unclamped for removal from the spindle bearing plate.

Abstract: A spindle brake for a spinning or twisting machine has a pair of arms whose jaws are engageable with the whorl of a spinning or twisting spindle. One of these arms carries a belt-lifting roller adapted to lift the belt away from the whorl when the brake is actuated thereby preventing friction between the belt and the immobilized whorl.

Abstract: A false twist device has a pair of fixedly positioned spindles whose whorls are driven by a tangential belt and whose friction discs overlap wtih each other and with the friction discs of a swingable spindle mounted on an arm which can be angularly displaced about a pivot axis parallel to the spindle axis but spaced outwardly from the triangle defined by the axes of the spindles.
