Abstract: A method for operating a textile machine producing cross-wound packages has a multiplicity of autonomous work stations that each have a spinning apparatus and a winding apparatus and are equipped with a suction nozzle, connected to the vacuum network of the textile machine, for receiving a thread from the surface of a cross-wound package, and also a storage nozzle, likewise connected to the vacuum network, for temporarily storing excess thread length, and which is operated at least by one service unit that exchanges full cross-wound packages for empty tubes as required. The invention provides for the actuation of a cross-wound package/empty tube exchange by one of the service units to be prevented during the operations of restarting of the work stations, thereby ensuring that, during the restarting of the autonomous work stations, the maximum number of work stations always starts up again at the same time.

Abstract: The invention relates to a sleeve plate designed to support and center a bobbin sleeve, comprising: a centering projection; and a main body, in particular circular in design, further designed in particular in a plate-like manner, with a surface side. The centering projection can be designed in particular to be received by an opening in an end face of the bobbin sleeve. The centering projection is arranged in a rotationally centered manner on the surface side of the main body and projects from this surface side and is designed in such a way as to center the bobbin sleeve when the bobbin sleeve is in the received state. The centering projection has a lateral surface.

Abstract: A servicing apparatus for automatic repair of yarn breaks in open-end spinning machines is provided with a device for replacing finished yarn packages with empty tubes, and a multi-functional yarn manipulating element having a work head equipped with a yarn brake and a contoured yarn guide element, the manipulating element being selectively movable between a position (c) at a top end of the tube for forming a top winding at the completion of winding a full yarn package, a position (a) at a base end of the tube for forming a yarn reserve winding upon beginning the winding of an empty tube, and a position (b) moving axially along the tube to prevent the creation of parallel windings during the repair of a yarn break.

Abstract: An open end spinning machine with an associated service device having a supplementary yarn conveying device utilizing a delivery tube disposed on a delivery tube holder which can be pivoted into various work positions. A yarn guide plate is movably seated in the area of the delivery tube holder and has a yarn guide notch as well as a yarn placement slit and can be selectively controlled by means of a thrust cylinder. By pivoting the yarn guide plate, the yarn extending through the yarn guide notch is transferred to specially designed yarn catch devices of a tube supporting disk seated in a creel of a work station of the spinning machine. Subsequently, the grasped yarn slides automatically into the yarn placement slit which is disposed below the notch and, while being securely guided in the yarn placement slit, is wound as a reserve winding on the empty tube rotating in the creel.
