Abstract:
Provided are a reinforcement material, not causing undesired stress and having excellent shape stability characteristics, a rubber product using the material and a method for producing the product, and a pneumatic tire using the material and a method for producing the tire. The reinforcement material for rubber has a flat coil shape where, when the material is in a single free state, loop portions are partly superposed on each other in sequence, and is embedded in a rubber product such as a pneumatic tire.

PCT No. PCT/EP96/03885 Sec. 371 Date May 15, 1998 Sec. 102(e) Date May 15, 1998 PCT Filed Sep. 4, 1996 PCT Pub. No. WO97/12092 PCT Pub. Date Apr. 3, 1997For reinforcing rubber or plastics articles, particularly pneumatic tires, a wire filament is proposed which is spirally shaped and exhibits no elastic residual torsional stresses. A wire filament 8 according to the invention is produced by twisting drawn straight wire filaments 2 into the range of plastic deformation with subsequent return-twisting, at least two wire filaments being brought together and combined prior to return-twisting. Preferably at least two wire filaments 2 are brought together by means of a perforated disk 30, twisted about each other and plastically deformed in a false twister 20 and subsequently return-twisted in a further false twister 40.
Abstract:
PURPOSE: A process of steel cord of rubber reinforcing serves rubber adhesive power apparatus of steel cord and durability increase of rubber product by gaining steel cord of effective structure to remove central cavity of rafter(1x3), reduces manufacturing time, simplifies manufacturing device, increases energy efficiency by composing to rotate device itself using rotary driving power of stranded-wire apparatus without additional power. CONSTITUTION: The process of steel cord(20) of rubber reinforcing comprises rolling process to roll core wire(20a) of flat shape section; twisting process by screwing core wire(20a) of flat shape section to center line; stranded-wire process to be twisted by combining core wire(20a) and outer stainless wire(20b) at least one among twist direction and twist pitch of core wire(20a) by being different from twist direction and twist pitch of cord; twist direction of core wire(20a) and twist direction of cord is opposed; rolling process for core wire(20a) and twisting process by screwing core wire(20a) to be executed simultaneously.

Eine Richtvorrichtung (1) zum Richten von Kabeln (2) weist zwei Rollenreihen (3, 4), eine Einstelleinrichtung (5) zum manuellen Einstellen des Abstands (d) zwischen den Rollen (20.1 .. 20.6; 21.1 .. 21.7) den beiden Rollenreihen (3, 4), eine Messeinrichtung (6) zum Erfassen des Abstands (d) zwischen den Rollen (20.1 .. 20.6; 21.1 .. 21.7) der Rollenreihen (3, 4) sowie eine Anzeigeeinrichtung (8) auf, mit der Abweichungen des mittels der Messeinrichtung (6) ermittelten Ist-Werts des Rollenabstands (d) von einem Soll-Wert visuell anzeigbar ist. Die Anzeigeeinrichtung (8) weist zwei optische Fehleranzeigeelemente (22, 23) zum Anzeigen eines gegenüber dem Soll-Wert des Richtparameters (d) zu hohen Ist-Wert oder zu tiefen Ist-Wert sowie ein optisches Gutanzeigeelement (24) zum Anzeigen, dass der Ist-Wert mit dem Soll-Wert übereinstimmt, auf.
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).
Abstract:
A helical cord having an elliptical shape and the like is manufactured so that a length-to-width ratio or a dimension of a shaped form of the cord to be shaped in a longitudinal direction can be changed. A cord (C) is sequentially passed through through holes (21H, 22H) of stationary and movable shaping bodies (21, 22) opposing each other of a shaping device (20). At that time, the movable shaping body (22) is moved along the stationary shaping body (21) by a moving device so that the through holes (21H, 22H) become eccentric with respect to each other, and the cord (C) passing between the eccentric through holes (21H, 22H) is bent and deformed so as to be shaped. Also, a first and a second displacement mechanism that displace the movable shaping body (22) in X- and Y-directions are provided in the moving device, the movable shaping body (22) is thereby reciprocatingly displaced in the both directions in synchronization by displacement amounts which were set, respectively, the movable shaping body (22) is continuously moved in response to the displacements in the both directions, and thus the passing cord (C) is shaped.
