  • Patent number: 11946200
    Abstract: A stranding machine is provided for producing a cord from a plurality of wires, preferably metal wires. The stranding machine has a stranding device for stranding the wires, including at least one rotatably mounted deflecting roller for deflecting the cord and at least one guide device for guiding the cord. The guide device is arranged in such a way that the cord can be guided on a straight line from the guide device to the deflecting roller in such a way that the cord is pressed against a first flank of the deflecting roller. As the cord is deflected by the deflecting roller, the cord moves from the first flank into the roller base of the deflecting roller.

  • Patent number: 10612171
    Abstract: The invention relates to a bobbin carrier for receiving a bobbin which is set up for unwinding a strand material, wherein the bobbin carrier is provided for use in a braiding, winding or spiraling machine and is set up to rotate relative to the machine during operation of the latter. The bobbin carrier has a tensile-force measuring device for measuring the tensile force of the strand material unwound from the bobbin and has a first data transfer device for transferring data. According to the invention, the first data transfer device is set up to transfer measured tensile force values to a second data transfer device arranged outside the bobbin carrier. As a result, too low or too high tensile forces in the strand material can be detected early at the individual bobbin carriers.

  • Patent number: 10329712
    Abstract: Flyer bow for a wire-braiding or cable-twisting machine, comprising a bow member that has a groove extending essentially along the entire longitudinal extension of the flyer bow in the longitudinal direction of the flyer bow. The flyer bow comprises a tubular guiding element, especially a coil spring, for guiding the elongate strand-type material that is placed in the groove without interruption, essentially along the entire longitudinal extension of the groove. The inner dimensions of the groove at any point along the longitudinal extension of the guiding element are greater than or equal to the outer dimensions of the guiding element at the same point. This makes it easy to remove and introduce, preferably pull out and insert, the guiding element from and into the groove.

  • Patent number: 6062506
    Abstract: A process and device are disclosed for producing a package of elongated winding material. A winding bobbin (50) has a conical winding core (52) and a first detachable flange (53) arranged at the side of the winding core (52) having the smaller diameter, and a second flange (54) arranged at the other side of the winding core (52). The winding bobbin (50) is held in a winding device by means of bobbin holding members (103, 104) which center both flanges (53, 54) and are supported on their surface opposite to the winding core (52). The elongated winding material (D) is then wound on the bobbin (50), the winding process being controlled in such a way that a predetermined type of bobbin is obtained. In particular when a plastic bobbin (50) is used, the package is easy to transport but is at the same time very resistant, so that additional packaging measures may be dispensed with. Packaging waste may thus be almost entirely avoided.
