The tension in the filaments is controlled by creating an adjustable opposition to the pulling action of the filament advancing assembly (16) on the filaments thereby ensuring the production of a high quality stranded cable.Type: GrantFiled: March 21, 2001Date of Patent: May 14, 2002Assignee: Lefebvre Frères LimitèeInventor: Michel Brazeau

Patent number: 6318061Abstract: In the method for manufacturing a cable (CA1), the individual leads (AD1 through ADn) are supplied to a stranding apparatus (RE, RA) that produces a stranded bundle (SB1), whereby the material (MMA1) for the cable cladding (MA1) is applied onto the stranded bundle (SB1) produced in this way with an extruder head (EK1), and the stranding point for the stranding lies in the region of the extruder head (EK1). The individual leads (AD1 through ADn) are already brought into contact with the material (MMA1) for the cable cladding (MA1) when or before they have just been completely stranded to form the stranded bundle (SB1).Type: GrantFiled: February 8, 2000Date of Patent: November 20, 2001Assignee: Siemens AktiengesellschaftInventors: Reiner Schneider, Edgar Heinz, Thomas Müller

Publication number: 20010011450Abstract: An apparatus (310) for manufacturing stranded cables comprises a supply spool assembly (320, 322) having filaments wound thereon, and a flyer (316) mounted for rotation about a central axis for imparting a rotational movement to the filaments, while guiding them axially through the apparatus (310). The filaments are wound together as they pass a gathering point centrally disposed to the central axis and downstream of the flyer (316). A filament advancing assembly (16) is provided downstream of the gathering point to impart an advancing speed to the filaments. A control system allows for the control of the number of revolutions of the flyer (316) per unit length of filaments advancing through the gathering point to ensure that a constant helical pitch is obtained.

Patent number: 6260343Abstract: Strands and wire ropes composed of materials such as high carbon steels and stainless steels can be provided in a compacted, mechanically stress relieved and thermally stress relieved condition. The wires are compacted during stranding to form the individual strands of the wire ropes. The wires can be thermally stress relieved prior to stranding to remove tensile residual stresses. Compaction produces a compressive residual stress state in the strands which increases fatigue resistance. The strands can be thermally stress relieved subsequent to closing. The wires and strands can be heated using a process such as induction heating. The wire ropes can be torque balanced or rotation resistant. The wire ropes have high strength, a high strength-to-weight ratio and enhanced fatigue life. Stainless steel wire ropes also provide corrosion resistance.Type: GrantFiled: April 28, 1999Date of Patent: July 17, 2001Assignee: Wire Rope Corporation of America, IncorporatedInventor: Bamdad Pourladian

Patent number: 6256872Abstract: The improved musical string includes a prior art core wire assembly including a core wire and a terminal end. The cover wire has an end portion that is bent around the terminal end portion of the core wire, and the cover wire is then wound the core wire to form the musical string. The improved cover wire winding machine includes a headstock with a rotatable spindle and a core wire terminal end mounting hook. A cover wire mounting sleeve is slidably and rotatably engaged to the spindle and functions to mechanically engage an end of the cover wire and to bend it into engagement with the core wire terminal end following engagement, the cover wire is wound around the core wire to produce the improved musical string.Type: GrantFiled: October 30, 1998Date of Patent: July 10, 2001Inventors: Jeffrey E. Landtroop, Donald A. Dykstra

Patent number: 6098392Abstract: This invention relates to a new cable-twisting process for making yarns suitable for use in carpets. The process involves cable-twisting together two component yarns. At least one of the component yarns comprises two singles yarns co-twisted but not cabled together. The singles yarns may be differentially colored to provide the resulting multi-colored cable-twisted yarn with good color separation and vividness.Type: GrantFiled: June 18, 1998Date of Patent: August 8, 2000Assignee: E.

Patent number: 6089007Abstract: A fusion-bonded carpet system and method of manufacture which method includes providing as all or a portion of the wear face surface cut yarn material in rope form prepared in rope bundles and implanting one or both ends of the rope bundle in an adhesive layer on a backing sheet to provide one or two I-bond, fusion-bonded carpet material having a selected pattern on the wear face surface. The fusion-bonded carpet has a wear face surface composed of all or part of a yarn material in rope bundle form, for example, of a multicolored random or selected pattern. The carpet material may have a backing layer and form carpet tile.Type: GrantFiled: July 25, 1997Date of Patent: July 18, 2000Assignee: Interface, Inc.Inventors: Wayne M. Hamilton, David K. Slosberg

Patent number: 6076344Abstract: Process for producing a steel cord for pneumatic tires comprising a bunch of wires, the core of which consists of wire filaments 10 arranged bunched juxtaposed in parallel. Preferably at least three wire filaments 10, 20 are provided, at least two wire filaments located juxtaposed in parallel being spirally shaped as core filaments 10 forming a core 60 and at least one wire filament spirally surrounding the two core filaments 10 as a sheathing wire 20. Spirally shaping the wire filaments 10 is achieved in accordance with the invention by false twisters 40. Due to this spiral shaping of the wire filaments 10 migration of the filaments from the core composite is avoided more particularly. The residual torsional stresses of the core filaments among each other and in conjunction with the restoring forces of the sheathing wire are advantageously cancelled. In addition, the steel cord features to advantage a flattened, more particularly, oval shape.Type: GrantFiled: July 17, 1998Date of Patent: June 20, 2000Assignee: Drahtcord Saar GmbH & Co.
