A method and apparatus for welding lines having metallic braids or strands to form an end node or transit node by introducing a first portion of each line into a compression space of an ultrasonic welding apparatus, wherein the first portions run along a straight line, wherein at least one line has a component at a distance from the end node or transit node to be welded, and at least the line which has the component is attenuated between the compression space and the contact element in a second portion by a change in profile of the line which is imposed using a deflection device. To this end, the line which has the component is oriented in extension of the straight line.

A winding device 100 which winds a wire 3 around a core 11 includes the core 11, which rotates axially and around which the wire 3 is wound; a roller 21 which rotates axially and feeds the wire 3, which is wound around the roller 21, to the core 11; and a tension device 15 which adjusts a tension of the wire 3 that is supplied to the core 11 from the roller 21. A winding shape and a winding diameter of the wire 3 wound around the roller 21 are substantially identical to a winding shape and a winding diameter of the wire 3 wound around the core 11.

A thread feeding buffer for feeding a fibre thread (15) from a magazine roll (14) to a feed apparatus at a robot arm which is freely movable in the room. The thread feeding buffer comprises thread brake means (16, 19, 20) and at least one movable thread guide (17), on which a thrust force is acting. The thread is running from the magazine roll (14), via the brake means (16, 19, 20), through the thread guide (17) and further on towards the feed apparatus in such a way, that the thrust force acts for creation of a thread buffer between the brake means and the feed apparatus, which buffer is variable in length. At least one guide rod for guiding the movable thread guide is provided with means arranged to cause a braking effect on downward movement of the movable thread guide for preventing entanglement of the thread fed through the movable thread guide following a rapid fall of said movable thread guide.

Es wird eine Anlage (10) zum hochproduktiven exakten Aufwickeln eines Profilstranges (12) aus einem elastischen Material auf eine Spule (14) beschrieben. Die Anlage (10) weist eine Bandzufuhreinrichtung (24) auf, die mit einer Zugspannungsregelung (26) ausgebildet ist. Die Bandzufuhreinrichtung (24) ist in der Höhe derartig verstellbar, daß der auf die Spule (14) aufzuwickelnde Profilstrang (12) stets horizontal tangential zur Spulen-Wickelstelle (30) zugeführt wird.
摘要:
The invention relates to a process and a device for winding and/or unwinding multi-wire coils (10) in which several wires (3), especially wires (3) of low plastic deformability, like steel wires, are simultaneously wound on a multi-wire coil (10) and/or such wound wires (3) can simultaneously be unwound in the stranding device (12) and subsequently stranded. It is to be possible for the wires (3) to be double-twist stranded together while maintaining quality, i.e. ensuring the same length ratios in the wire layers on the multi-wire stranding principle on highly productive stranding machines. This is attained in that, during the winding process in a winding device (1), individual wires (3) are taken from stationary feeds (2) and taken to a dedicated compensating storage device (7) and several of said wires (3) are wound at a bunch of approximately parallel wires (3) on a common multi-wire coil (10), and during the unwinding of the bunch of wires (3) from a multi-wire coil (10) thus wound which is received in an unwinding device of a stranding device designed as a coil support (19) the individual wires (3) are taken to a stranding process via a dedicated compensating storage device (7').

This invention relates to a tensioning and drawing-back device provided for keeping tension and if necessary drawing back warp yarns (2) led from a bobbin (1) to a weaving machine. It comprises a supporting body (6) with a curved friction surface in order to support the warp yarn (2) between the bobbin (1) and the weaving machine, and a first (7) and a second tensioning element (8) which exert a tensile force on the warp yarn (2) respectively in front of and behind the curved friction surface (6). The tensioning elements (7), (8) can be suspended from the warp yarn (2) and for example only through their own weight exert this tensile force. This device works very well and can draw back the warp yarn (2) out of the weaving area better than the known devices. Furthermore this device can be made with simple means and for a relatively low price. The replacement of a bobbin (1) can furthermore also occur without interruption or disturbance of the weaving process.
摘要:
A storage device (E) for the weft yarn (W1,W2) of a power loom (L), wherein several yarn deflector elements (A-D, 61-65) are arranged along the path of the yarn leading from the yarn reserve to a feeder device (M) and at least one of said elements can move in relation to at least one other element in perpendicular manner with respect to the longitudinal direction of the yarn between a feed position (wherein the yarn runs in a substantially drawn position) and a storage position (1) in which the yarn runs in the form of a zigzag . One regulating device with at least one drive mechanism (71-7B) is provided and connected to each moveable yarn deflector element. A yarn tension damper is integrated into the storage device (E), having at least one first yarn deflector element (A) which can move in the direction in which the yarn is fed as an elastically readjusting damping element (N) moving towards the end of the feed when the yarn is tensioned.
