Abstract:
A pneumatic tyre comprises a belt (7) disposed radially outside a carcass (6) in a tread portion (2), the belt (7) comprising two crossed plies (7A,7B) of monofilament metallic cords (10A,10B,10C) laid at angles of from 15 to 30 degrees with respect to the circumferential direction of the tyre, each monofilament cord being composed of a waved single filament, the filament having a circular sectional shape having a diameter in a range of from 0.40 to 0.50 mm, or alternatively a non-circular sectional shape having an aspect ratio in a range of from 0.65 to 0.95 and a cross-sectional area in a range of 0.09 to 0.20 sq.mm.
Abstract:
A high tensile steel strand for civil engineering applications comprises a core wire (11) and a ring of outer wires (12) arranged in a helical pattern around the core wire and in contact with the core wire. The number and the diameter of the outer wires in relation to the core wire are such that there are significant gaps (13) between adjacent outer wires. The strand is used as an anchorage in rock and a bonding agent between the strand and the rock penetrates gaps (13) to provide effective bonding. The strand is sufficiently flexible to be inserted in deep bores in rock even when surrounding space does not permit straight insertion of the strand.
Abstract:
Floatable cord for use especially as a head rope of a net, the interior of the cord comprising floating material (1) having a density lower than 1,0. The floating material (1) is manufactured of a thermoplastic, cross-linked or non-cross-linked plastics material, wherein empty spaces are provided for decreasing the density and which in the longitudinal direction of the cord forms a continuous core region of a constant cross-section, or a core region widening and narrowing in a wave-like fashion.
Abstract:
A metal cord usable for the reinforcement of rubber articles is comprised of a helically formed single wire filament having a twisting angle of 75-84.5° or a bundle of two twisted metal filaments each having a twisting angle of 75-84.5°. Such metal cords are preferably used as a rubber reinforcement in a pneumatic tire.
Abstract:
A steel cord for reinforcement of rubber products composed of two material wires of a diameter of 0.25 to 0.40 mm and a carbon content of 0.75 to 0.88 wt % which are entwisted at a twist pitch of 9.0 to 16.0 mm and in open structure, with improved fatigue resistance, flexibility and corrosion resistance.
Abstract:
There is disclosed a method of stranding together a plurality of strands (7) of sectorial cross-section around an optical fiber unit (2) which serves as a central wire material. First, a rigid type stranding machine is used to impart spiral twist to each strand (7). Subsequently, the twisted strand (7) is heat-treated to remove its strains. These strands are then fed to a planetary type stranding machine which provides planetary motion in which they make orbital rotation around the optical fiber unit (2) without making own-axis rotation, whereby they are stranded together on the optical fiber unit (2).
Abstract:
@ Verfahren zum Herstellen eines mehrlagigen, einlitzigen und kompakten Verstärkungscordes für elastomere Erzeugnisse in einem Verseilvorgang, durch Zuführen von Metalldrähten gleichen Durchmessers in mehrere hintereinanderliegende Verseilpunkte, wobei zwei oder mehr Metalldrähte dem ersten Verseilpunkt zugeführt werden, dadurch gekennzeichnet, dass den dem ersten Verseilpunkt folgenden weiteren Verseilpunkten jeweils höchstens soviele Metalldrähte zugeführt werden, wieviele Plätze vorhanden sind, bei denen jeder zugeführte Metalldraht mit mindestens zwei bereits vorhandenen Metalldrähten in Berührung gebracht werden kann.
Abstract:
Richtvorrichtung (100) zum Richten von Kabeln (1) mit einer eingangsseitigen Rollenanordnung (110) und einer ausgangsseitigen Rollenanordnung (120), sie so angeordnet sind, dass ein zu richtendes Kabel (1) in Transportrichtung (X) betrachtet zwischen Rollen (111, 112, 113) der eingangsseitigen Rollenanordnung (110) hindurch in die Richtvorrichtung (100) gelangt und nach dem Hindurchtreten zwischen Rollen (121, 122, 123, 124) der ausgangsseitigen Rollenanordnung (120) die Richtvorrichtung (100) verlässt, wobei ein Abstand (d) zwischen zwei Rollen (122, 123) der ausgangsseitigen Rollenanordnung (120) einstellbar ist. Ausserdem ist eine Kraft (F) vorgebbar, die zwischen zwei Rollen (111, 112) der eingangsseitigen Rollenanordnung (110) senkrecht zur Transportrichtung (X) auf das Kabel (1) einwirkt.
