Abstract: A vehicle wheel and tire assembly. In the event of an emergency operation, the pneumatic tire contacts a support member of the rim. A stabilizing arrangement protects the wheel and tire assembly from moving in an uncontrolled manner. This stabilizing arrangement is in the form of a corrugation, which is provided both on the inner surface of the tire and on the support member of the rim. This corrugation, which can be a fine groove system, reliably assures that the tire and the rim are provided with steering stability, especially when driving in curves.

Abstract: A method and apparatus for electrostatically flocking a thread-like or yarn-like material. This material rectilinearly and continuously or intermittently is moved through an electrical field which is generated between electrodes having non-planar yet symmetrical potential surfaces. This electrical field preferably is generated between curved potential surfaces of the electrodes. The flock is shot into the adhesive coating of a given thread not only radially but also at an angle. The thread does not have to be turned. As a result, a dense and improved flocking is achieved all around the yarn or thread in a simple and economical manner.

Abstract: A flocked, sheet-like article which includes adhesive foam and flock. After the flocking, the article is partially dried and calendered. The sheet-like, textile article obtained in this way is light, air permeable, bi-elastic, and has a matted, flannel-like surface. The article can also be embossed.

Abstract: A vehicle wheel having a one-piece wheel rim on which can be mounted a pneumatic tire. The tire has a tread strip, two sidewalls, a carcass, and two tire beads which are laterally spaced from one another and contain substantially inextensible bead cores. The wheel rim has two rim shoulders, which are laterally spaced from one another and extend outwardly into a respective rim edge or into a respective rim flange. The rim also has a radially recessed rim base. The wheel further includes an emergency operation support member which is disposed in the recessed rim base and has a supporting surface which is located radially outwardly of the rim flange. The emergency operation support member is provided with a radially inner surface which faces the rim shoulder and is disposed at a distance from the latter, this distance corresponding to at least the thickness of the tire bead. An annular chamber is provided which extends further radially inwardly to the recessed rim base, and is widened axially inwardly.

Abstract: A method of treating the surfaces of elastomeric unvulcanized molded objects or semi-finished products for use in further manufacturing; the surfaces are neutralized with a separating material in the form of unvulcanized powdery rubber. This produces a good neutralization and an improved product quality, especially with objects which are produced by vulcanization.

Abstract: A screw extruder for mixing, homogenizing, and degassing highly viscous rubber mixtures and similarly acting thermoplastics. The extruder has mixing pins associated with the housing in the mixing and homogenizing zone, and degassing pins associated with the housing in the degassing zone. The degassing pins have passages or channels through which gases and vapors are withdrawn. The retaining or damming structure at the entrance to the degassing zone can also be formed of pins associated with the housing. The conveyed material is mechanically and thermally satisfactorily made uniform by the inventive pin arrangement without material shearing forces, and can also be effectively and favorably degassed. High flow-through rates of the material can be achieved with high product quality.

Abstract: A radial ply pneumatic tire is provided with a tread reinforcement including a first layer of at least one ply of tire cord fabric wherein the cords have a high modulus of elasticity. A second layer which overlies said first layer is at least one composite ply of tire cord fabric including a central strip of steel cords oriented at an angle of from 60.degree. to 90.degree. with the equatorial plane of the pneumatic tire, and two lateral strips abutting the central strip having cords formed from material possessing a low modulus of elasticity.

Abstract: A tire tread pattern wherein all the ribs have a continuous structure in the circumferential direction, and more or less transverse notches provided in a given rib extend a predetermined distance beyond the center-line of that rib from a circumferential edge thereof.

Abstract: A pneumatic vehicle tire having a tread provided with profiled ribs extending continuously in the circumferential direction, and with circumferential continuous grooves which separate the profiled ribs from each other. A plurality of meandering profiled ribs are provided, and their laterally outer side edges have obtuse-angled serrations or toothing. Inwardly, these ribs are provided with linearly extending blind grooves which are oriented at an angle to the circumferential direction. Block-rib parts are formed with an inclined gable embodiment. Furthermore, the circumferential grooves have a zig-zag shape.

Abstract: A pneumatic vehicle tire including a carcass, particularly a radial carcass, a tread, and a belt-like reinforcement formed of at least two cord plies radially superimposed one above the other. At least one of the plies has rubberized metallic cord elements, and the other suitably has non-metallic cord elements. The cord elements cross each other from ply to ply, and the width of at least one cord ply is approximately equal to the width of the tread. The metallic cord elements, which particularly are made of brass-plated steel wire, further comprise a core and a mantle of wire, with the mantle including several twisted individual wires of equal size. The metallic cord elements in the cord ply comprise a core of a single wire filament, and a mantle comprising at least three single wire filaments. The mantle wire filaments respectively have a part which radially engages the wire filament of the core.
