Abstract:
Luftreifen mit mindestens einem aus mehreren Stahldrähten zusammengesetzten, flach ausgebildeten Verstärkungscord, der eine längere und eine kürzere Querschnittsdimension aufweist, wobei der Verstärkungscord aus einem flachen, ungedrehten Kern besteht, um welchen mindestens sechs Einzeldrähte geschlagen sind, dadurch gekennzeichnet, daß der flache Verstärkungscord (6, 7) im Gürtel und/oder in der Decke derart angeordnet ist, daß die größere Querschnittsdimension des Verstärkungscordes zumindest annähernd parallel zur Gürtel- bzw. Deckenkontur angeordnet ist. Der Kern kann aus mehreren meist runden Stahlcorden zusammengesetzt sein, oder er besteht aus einem flachen Stahldraht (10).
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:
Ein, insbesondere drehungsfreies, Drahtseil weist ein Kernseit (1) in Parallel-Machart auf, das auf seinem Querschnitt im Ganzen verdichtet worden ist und/oder aus Profillitzen hergestellt worden ist, die sich von vornherein dichter zusammensetzen lassen.
Abstract:
Bei einem Paketkern für den Wulst eines Autoreifens weisen die Drähte (A, B, C) jeder Drahtlage (8) des Paketkerns (4) trapezförmigen Querschnitt auf. Zwischen den Drähten (A, B, C) der darüberliegenden nächsten Drahtlage (8) sind jeweils keilförmige Abstandsräume (9) vorhanden. Dadurch wird erreicht, daß die Drähte (A, B, C) jeder Drahtlage (8) sich auf den Kanten der Drähte der darunterliegenden Drahtlage abstützen, so daß sie sich während der Herstellung des Reifens nicht gegeneinander verschieben können.
Abstract:
The invention relates to a unit for producing an assembly (A) of filiform elements (14) wound together in a spiral, comprising: means (16) for twisting at least first and second filiform elements (14), arranged such as to twist the first and second filiform elements (14) separately from one another; means (18) for preforming at least the first and second twisted filiform elements (14) in a spiral, arranged downstream of the twisting means such as to preform the first and second twisted filiform elements (14) separately from one another; and means (20) for assembling at least the first and second preformed and twisted filiform elements (14), arranged downstream of the preforming means such as to form the assembly (A) of filiform elements (14).
Abstract:
A belt (16) for suspending and/or driving an elevator car includes a tension member (38) extending along a length of the belt (16), the tension member (38) including a plurality of fibers (24) bonded in a first polymer matrix (36), the plurality of fibers (24) extending parallel to and discontinuous along a length of the belt (16) and arranged with one or more lengthwise extending gaps (28) between lengthwise adjacent fibers (24). A jacket (40) substantially retains the tension member (38). A method of forming a tension member (38) for an elevator system belt (16) includes arranging a plurality of fibers (24) into a fiber bundle. The plurality of fibers (24) extend parallel to a length of the belt (16) and have one or more lengthwise extending gaps (28) between lengthwise extending fibers (24). The plurality of fibers (24) is bonded to a first polymer matrix (36).
