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: With the constant increase in spindle speeds, the attachment of the bobbin to the spindle becomes more difficult. To avoid detachable bobbins, the bobbin is integrated with the spindle. The spindle is installed together with its integrated bobbin. Yarn is wound on the spindle bobbin. In a modified version, there is a bobbin core tube firmly attached around and on the spindle core.
