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: A method of producing a fastening arrangement for the position-correct fastening of a component to a structural part of a motor vehicle comprises the steps: providing of the structural part; providing of a first tolerance compensation element and a second tolerance compensation element; positioning of the first tolerance compensation element, while holding the structural part firmly, relative to the structural part in a nominal position for the later position-correct fastening of the component to be fastened, and holding of the first tolerance compensation element in the nominal position, the first tolerance compensation element being positioned with a gap relative to the structural part; inserting of the second tolerance compensation element between the first tolerance compensation element and the structural part, so that the gap between the first tolerance compensation element and the structural part is bridged over; joining of the second tolerance compensation element to the first tolerance compensation el

Abstract: A connection arrangement for connecting two tube pieces of a crossmember for a vehicle has a first attachment element made of a first material, wherein the first attachment element is provided for a solid material-bonded connection to at least a first tube piece which comprises the first material. Furthermore, the first attachment element has a second attachment element which is fastened to the first attachment element, wherein the second attachment element consists essentially of a second material differing from the first material, wherein the second attachment element is provided for a solid material-bonded connection to a second tube piece which comprises the second material. Furthermore, a crossmember has such a connection arrangement.

Abstract: A crossbeam for a motor vehicle comprises a crossbeam body and at least one attachment device for attaching at least one vehicle component of the motor vehicle to the crossbeam, the attachment device having an attachment body which is fastened to the crossbeam body and extends in the longitudinal direction of the crossbeam body over a partial length of the crossbeam body and away from the crossbeam body in a direction transverse to the longitudinal direction, and a plurality of attachment elements being present on the attachment body. The attachment body is built up from a plurality of individual blanks which are fastened to the crossbeam body in a distributed manner over the partial length and which each extend with their longitudinal direction and with their blank area transversely to the longitudinal direction of the crossbeam body.

Abstract: In the case of a method for working a tube made from a metallic material, wherein at least one punching is made in a tube wall of the tube at at least one first circumferential location of the tube wall, the tube wall is provided, at at least one second circumferential location, which faces away from the first circumferential location in the circumferential direction, with at least one forming selected from the group that consists of at least one depression of the tube wall, at least one throughhole in the tube wall.

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.
