Abstract:
A high traction synthetic rope comprising a braided sheath (8) adhered to a synthetic strength member (7) by means of a first synthetic portion (9) and portions of material (23) adhered to the outside surface of the braided sheath by means of a second synthetic portion (21), where the portions of material (23) are formed of a substance that differs from a substance mainly forming the second synthetic portion (21) and exhibits greater friction when wet or with greasy conditions and measured on an iron surface than does the substance mainly forming the second synthetic portion. Also methods of manufacturing such a high traction synthetic rope are disclosed. The rope shows reliable traction on driven rotating elements during wet / greasy conditions.
Abstract:

Abstract:
Um ein Hochsicherheitsseil zu schaffen, welches geeignet ist, innerhalb relativ kurzer Zeit extrem hohe Kräfte aufzunehmen, wird ein Seil vorgeschlagen, welches aus einer Mischung verschiedener Kunststoffgarne oder Kunststoff garne und Metalldrähte besteht. Diese Kunststoff garne und Metalldrähte sollen in drei verschiedenen Verarbeitungsformen im Seil vorkommen, nämlich in einem Teil als ver zwirnte oder unver zwirnte Garne oder Drähte, aus einem zweiten Teil, der aus Zwirnen besteht und einem dritten Teil, der aus Korden gefertigt ist. Die Zwirne, sowie auch die Korde werden aus % verzwirnten oder unverzwirnten Garnen beziehungsweise Drähten hergestellt. Hierbei soll gemäss der Erfindung ein Zwirn aus zwei Garnen und ein Kord aus drei Garnen gefertigt sein. Solche Hochsicherheitsfangseile lassen sich vorteilhaft einsetzen im Automobilrennsport zur Verbindung eines Rades mit dem Chassis des Rennwagens sowie zur Anfertigung von Sicherheitsfangseilen, die zur Pistensicherung, als temporäre Lawinenf angnetze oder als temporäre Steinschlagschutznetze eingesetzt werden können.
Abstract:
A low stretch elevator rope (10) is obtained in which a plastic core (12) has a central strength member (18) that does not increase the weight of the rope by more than 5 %. Moreover, the plastic core (12) has a diameter exceeding 50 % of the diameter of the rope (10), when measured prior to winding steel strands (14) onto the core (12). The steel strands (14) that are wound around the core (12) are conventional and are so wound that the plastic material of the core (12) essentially fills the inner interstices (16) between the steel strands (14).
Abstract:
The invention concerns a composite cable comprising a plurality of strands (10, 12) stranded around a composite synthetic core (5) with a concentric structure: the core (5) consists of a nucleus (11) formed by a bundle of parallel synthetic fibres extending along the cable longitudinal direction, and of a compact thermoplastic sheath (13) enclosing said nucleus (11) and serving as winding support for the strands. The invention is particularly applicable to cables for lifting or for elevators.
Abstract:
Steel cord for a tire which is formed by twisting 3 to 5 steel filaments to form a side strand (5), disposing a core wire (9) or (10), formed of inorganic or organic strands of a type different from the steel filament, within a space surrounded by a plurality of the side strands (5) to form a steel strand, and then twisting a plurality of the steel strands.
Abstract:
The invention refers to a rope (3) made of a textile fiber material, comprising a rope core (6) as well as a sheath (7) surrounding the rope core (6), wherein the rope (3) comprises at least one antistatic multifilament yarn (5) or antistatic monofilament that is located in the rope core (6), in the sheath (7), in an intermediate sheath (8) located between the rope core (6) and the sheath (7) and/or in a reinforcement located between the rope core (6) and the sheath (7), wherein the antistatic monofilament or individual filaments (12) of the antistatic multifilament yarn (5) each comprise a conductive fiber core (13) sheathed with a non-conductive plastic sheath (14), and wherein the at least one antistatic multifilament yarn (5) or antistatic monofilament is twisted with a twine (16) or yarn of a different material, wherein the other material of the twine (16) or yarn mentioned is preferably UHMWPE or PES.
Abstract:
Provided is an elastomer reinforcement cord in which the problem of stress concentration at an interface between an elastomer and a metal cord is solved and the durability is thereby improved. The elastomer reinforcement cord includes metal filaments (1a) and (1b), and a polymer material (3) having a melting point or softening point of 80° C. to 160° C. The elastomer reinforcement cord has a core (11) and at least one sheath layer (12). In a region surrounded by a line connecting the centers of the metal filaments constituting the outermost sheath layer at a cross-section in a direction orthogonal to an axial direction after vulcanization, when a region occupied by other than the metal filaments is defined as a gap region, the polymer material is contained in this gap region, and a filling rate, which is a ratio of the area of the polymer material, is higher than 120%, taking the area of the gap region as 100%.
