Abstract: The package lift apparatus serves for lifting a wound yarn package in contact with a rotating drive roll which drives the yarn package in a textile machine. Known equipment of this type requires a considerable degree of manual operation or exhibits a relatively complicated, and thus, expensive construction which is prone to malfunction. These drawbacks are avoided with the inventive yarn package lift apparatus which contains a piston-and-cylinder unit, wherein the piston rod of the piston carries a package support member. During one time interval the piston is exposed to a drive force which moves the package support member against a lower region of the package surface and thus lifts the yarn package from the drive roll.

Abstract: An apparatus for winding a thread or the like upon a rotatable, conical bobbin tube by means of a rotatable friction drive drum containing a plurality of rotational elements adjacently arranged upon a common drive or driving shaft and contacting the bobbin package along a generatrix. A first one of the rotational elements is rigidly rotatably connected with the drive shaft and at least two further rotational elements are freely rotatably mounted upon a respective rotational or rotary bearing mounted at the drive shaft. In one specific embodiment a respective one of these two further elements is provided at each end of the first element and such further elements are intercoupled by a differential gear arrangement. Due to the differing surface speeds of the bobbin package and the friction drive drum abrasion or scuffing occurs at the site of mutual contact of the bobbin package and the friction drive drum, such abrasion damaging the wound thread material.

Abstract: A rotor braking apparatus at each spinning unit of an open-end spinning machine, wherein at each spinning unit, for stopping the rotor, said rotor is arranged to be pivotable from an operating position away from a drive belt into an idle position, in which position there is pressed against the rotor shaft a brake lever provided with a brake shoe. An additional mechanism is provided which activates the rotor brake shoe without pivoting the rotor shaft from its operating position.
