Patent number: 10760212Abstract: A method for producing a rope, wherein fiber bundles are applied with a liquefied matrix material upstream of and/or at a twisting point to form fiber strands, and are embedded into the liquefied matrix material during stranding, by which fiber strands a fiber core of the rope is formed and wires or wire strands are wound about the fiber core. The matrix material of the fiber strands is hardened after the stranding, and the fiber strands are subsequently stranded directly with one another without further application to form the fiber core. Preferably the fiber strands are heated, during or after the stranding thereof to form the fiber core, so that the matrix material softens at least individual of the fiber strands, preferably all the fiber strands, softens and connects with the matrix material of another of the fiber strands, and is subsequently hardened, forming an integral bond with one another.Type: GrantFiled: March 3, 2016Date of Patent: September 1, 2020Assignee: CASAR DRAHTSEILWERK SAAR GMBHInventor: Bruno Lauer

Patent number: 10190256Abstract: A device for producing a strand or a cable, in particular a wire strand or wire cable, which device includes a rotatable arrangement for feeding cords to a twisting point, at which the cords are to be twisted with one another, and an installation for heating at least one of the cords. The heating installation is rotatable jointly with the feed arrangement. The heating installation is designed to heat a cord provided for forming a center strand or a cable core and/or cords for forming outer strands, and preferably has burner for fuel and/or an electrically operated heater.Type: GrantFiled: July 2, 2013Date of Patent: January 29, 2019Assignee: CASAR DRAHTSEILWERK SAAR GMBHInventor: Bruno Lauer

Patent number: 10190257Abstract: A wire cable and a device and method for producing the wire cable, wherein a core strand is compacted and then braid strands are stranded on the core strand. The core strand is hammered before stranding of the braid strands in order to smooth the surface thereof. A plastic layer is applied to the core strand before stranding of the braid strands. The braid strands are pressed into the plastic layer while the plastic layer is heated. The core strand is a core cable and the braid strands are strands of the wire cable or the core strand is a heart strand and the braid strands are outer core strands of a core cable of the wire cable. A greater breaking strength of the wire cable is obtained by hammering the core strand in order to smooth it than by compacting a core strand with a roller compressor.Type: GrantFiled: December 17, 2013Date of Patent: January 29, 2019Assignee: CASAR DRAHTSEILWERK SAAR GMBHInventor: Bruno Lauer

Patent number: 9803316Abstract: A method and device for producing a rope, in particular a wire rope, a fiber rope or a rope having wire and fibers, wherein the rope is provided with a marking during the stranding thereof. The marking is changed during the stranding operation. Expediently, during stranding, the marking is provided successively with details characterizing the stranding progress. The details include production parameters, for example information relating to the length of the rope already formed, about raw materials used, the stranding speed and/or the current stranding time. The details are provided on a wire, a wire strand and/or a marking strand, wherein the details are printed on the wire, the wire strand or the marking strand or are embossed in the wire, the wire strand or the marking strand, and/or chips, preferably radio chips, are arranged in the rope.Type: GrantFiled: June 12, 2013Date of Patent: October 31, 2017Assignee: CASAR DRAHTSEILWERK SAAR GMBHInventor: Bruno Lauer

Patent number: 9657439Abstract: A method for producing a strand or cable, in which fibers and/or wires are twisted at a twisting point to form the strand or cable. The fibers and/or wires are coated with a liquefied matrix material before and/or at the twisting point and are embedded in the matrix material during twisting. The fibers and/or wires are immersed in the matrix material before and/or at the twisting point and the formed strand or the formed cable is cooled after the twisting in order for the matrix material to solidify, preferably by air or in a cooling liquid, for example water.Type: GrantFiled: February 13, 2012Date of Patent: May 23, 2017Assignee: CASAR DRAHTSEILWERK SAAR GMBHInventor: Bruno Lauer
