Abstract: The anti-slip device comprises a plurality of linkages stretched over the tread of a vehicular tire. The ends of the linkage are formed into loops and extend over the tire sidewalls. In the proximity of the loops are a plurality of binder covered frames attached to the sidewalls in equal segments of space. Protruding from the binder is an extension adapted to be connected with and penetrate the end loops of the linkages to fasten the linkages on the tire tread.

Abstract: A fastening member provided at the end of a spring-elastic mounting strap of a tire chain. The fastening member has an introduction passage and an attachment passage for a cooperating fastening member that is secured to the other end of the mounting strap. A guide passage interconnects the introduction passage and the attachment passage. This guide passage, at the level of a hook arm portion that partially separates the introduction passage from the attachment passage, extends at an angle of greater than 90.degree. relative to the longitudinal axis of the attachment passage. In this way, the cooperating fastening member can be easily hooked in the fastening member. The inclined course of the guide passage relative to the longitudinal axis of the attachment passage assures a high degree of protection against accidental unhooking.

Abstract: In the feeding of sheet material to a machine such as a tire building former a sheet is first placed on a table and one edge of the sheet is aligned with a first datum line, preferably by tilting the table and supplying floatation air under the sheet. The sheet is then picked up and moved transversely through a predetermined distance by a gripping device to align the edge with a second datum line so as to enable the sheet to be fed in appropriate alignment to a machine.

Abstract: Disclosed herein is a pneumatic radial tire for a passenger car wherein, among a plurality of belt layers, a belt layer or layers consisting of aromatic polyamide fiber cords are disposed on the side of a carcass layer, a belt layer or layers consisting of carbon fiber cords are disposed on the side of a tread portion in the proximity of the belt layer on the carcass layer side, the end portions of at least one of the belt layers on the carcass layer side, consisting of the aromatic polyamide fiber cords, are bent towards the tread portion so that the bent portions cover the end portions of the belt layer on the tread portion side, consisting of the carbon fiber cords.

Abstract: Disclosed is a high-performance tire in which a bead filler formed of a rubber composition fills up a space between each turn-up portion of the carcass and a major portion of the carcass and extends to some extent along the carcass toward the tread. The rubber composition is anisotropic such that the elastic modulus in the direction circumferential of the tire is distinctly higher than in the direction radial of the tire. Such anisotropy can be produced by incorporating short fiber of a suitable thermoplastic polymer such as nylon into the rubber composition. This tire provides both improved controllability and a good ride.

At its side walls, the outer body is provided with respective bead cores in which area, the inner body of the tire is connected to the outer body.

Abstract: An apparatus for aiding in the mounting of tire chains having a flat base and two upward projecting angle members positioned parallel is disclosed. The angle members have first and second apices respectively positioned relative to one another and the road surface such that an encroaching tire is first engaged across its width by a first apex. The tire is supported on both apices, sized and positioned such that a cross-link of a tire chain positioned therebeneath remains movable, so that a snug and uniform fit of a tire chain is achievable. The apparatus is also useful as a support base for a jack and as a wheel chock.

Abstract: A method and closure are provided for sealing and repairing a puncture of a tire. The closure is a resilient plug of a rubber-like material stiffer and more durable than prior closures having a generally cylindrical shank portion and an adjoining circular head portion. The periphery of the shank portion has a labyrinth of closely spaced sealing rings and grooves therebetween. When the shank portion is forcibly engaged with a puncture, the sealing rings individually radially compress and locally conform to the size and shape of the puncture thereby providing multiple sealing members with the puncture. Additional sealing is provided by an auxiliary sealing ring on the head portion of the closure which is adhesively bonded to the inner surface of the tire, adjacent to the puncture. Tool attaching means are provided on the closure for forcibly engaging the closure with the puncture.

Abstract: A tire pressure regulating unit for modifying the air pressure in vehicle tires while traveling. Shutters, which are arranged between the tire and the tire control valve, have parallel-connected auxiliary valves which release an additional passage cross-section when the regulation pressure decreases. The shutters may also be provided on the other side of the tire control valve in the work line in the region of the wheel hub, with rapid release valves being connected in parallel to the shutters and permitting bleeding to the atmosphere upon a decrease of regulation pressure. In this way short bleeding times are achieved even for low regulation pressures.

Abstract: A tire which is formed by tying a knitted fabric spacer onto the tire mold core, spot welding the belt or other reinforcement to this spacer and then forming the tire body of a castable and/or sprayable elastomer.
