Abstract:
The invention relates to a cable (C) gummed in situ and including: an inner layer (CT1) of the cable including N1 internal wire(s); an outer layer (CT3) of the cable including N3 external wires helically wound around the inner layer of the cable; and a gumming rubber composition (20) placed between the inner layer of the cable and the outer layer of the cable. The rubber composition (20) includes a Formula (I) compound, or a salt of said compound, wherein: each group R1, R2, and R3 is independently an alkylene, arylene, arylalkylene, alkylarylene, or cycloalkylene group; each group X1 and X2 is independently -COOH, -CO-NH-OH, -SOOH, -PO(OR)(R') or -PO(OR)(OR'), R and R' independently being hydrogen or an alkyl group; and X3 contains at least one -COOH, -CO-NH-OH, -SOOH, -PO(OR)(R') or -PO(OR)(OR') group, R or R' independently being hydrogen or an alkyl group.
Abstract:
The invention relates to a device for producing a strand or a cable, in particular a wire strand or wire cable, which device comprises a rotatable arrangement (2) for feeding cords (3, 4) to a twisting point (5) at which at which the cords (3, 4) are to be twisted with one another, and an installation (1) for heating at least one of the cords (3, 4). According to the invention the heating installation (1) is rotatable jointly with the feed arrangement (2). The heating installation (1) is advantageously designed to heat a cord (3) provided for forming a centre strand or a cable core and/or cords (4) for forming outer strands, and preferably comprises a burner (6) for fuel and/or an electrically operated heater (7).
Abstract:
A hybrid rope (40) or a hybrid strand (50) comprising a core element (42, 52), a first (44, 54) and a second (46, 56) metallic closed layer surrounding said core element (42, 52). The core element (42, 52) includes a bundle of synthetic yarns. The first metallic closed layer (44, 54) includes a plurality of first strands of wires helically twisted together with the core element (42, 52) in a first direction. The second metallic closed layer (46, 56) includes a plurality of second wires or strands helically twisted together with said core element (42, 52) and said first metallic closed layer (44, 54) in a second direction. The cross-sectional area of the core element (42, 52) is larger than the total cross-sectional area of the first (44, 54) and second (46, 56) metallic closed layers. A corresponding method of producing such a hybrid rope or hybrid strand is also disclosed.
Abstract:
A method for manufacturing a component includes a step of providing at least one metallic element. A surface of the at least one metallic element is modified to facilitate a bonding of the at least one metallic element to a polymeric layer. The polymeric layer is then bonded to the at least one metallic element to form the component.

Abstract:
A steel cord (10) adapted for the reinforcement of elastomers comprises: a core steel filament (12) with a core steel filament diameter d c and coated with a polymer (14); six intermediate steel filaments (16) with an intermediate steel filament diameter d i smaller than or equal to the core steel filament diameter d c ; these intermediate steel filaments (16) are twisted around the core steel filament (12); ten or eleven outer steel filaments (18) with an outer steel filament diameter d o smaller than or equal to the intermediate steel filament diameter d I ; these outer steel filaments (18) are twisted around the intermediate steel filaments (16), the outer steel filaments (18) are preformed in order to allow rubber penetration inside the core (10). The core steel filament (12), the intermediate steel filaments (16) and the outer steel filaments (18) all have a tensile strength at least 2600 MPa. The cord (10) has an outer diameter D according to following formula: D ≤ d c + 2xd i + 2xd o + 0.1 wherein all diameters are expressed in millimeter (mm).
Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines Seils (1), bei dem Faserbündel (2) zur Bildung von Faserlitzen (3) vor und/oder an einem Verseilpunkt mit einem verflüssigten Matrixmaterial (5) belegt und beim Verlitzen in das verflüssigte Matrixmaterial (5) eingebettet werden, mittels der Faserlitzen (3) ein Faserkern (6) des Seils (1) gebildet wird und um den Faserkern (6) Drähte oder Drahtlitzen (7) gewunden werden. Erfindungsgemäß wird das Matrixmaterial der Faserlitzen nach der Verlitzung verfestigt und die Faserlitzen (3) werden zur Bildung des Faserkerns (6) anschließend ohne weitere Belegung unmittelbar miteinander verseilt. Zweckmäßigerweise werden die Faserlitzen (3) bei oder nach ihrer Verseilung zu dem Faserkern (6) erwärmt derart, dass das Matrixmaterial (5) zumindest einzelner der Faserlitzen (3), vorzugsweise sämtliche der Faserlitzen (3), erweicht, sich mit dem Matrixmaterial (5) jeweils anderer der Faserlitzen (3) verbindet und anschließend unter Bildung eines Stoffschlusses untereinander verfestigt wird. Die Erfindung betrifft ferner ein mittels des Verfahrens herstellbares Seil.
