Abstract: A tread configuration for pneumatic vehicle tires, especially for spare tires. A number of rectangular depressions are arranged in succession and next to each other in the circumferential direction of the tire. Transverse ribs and circumferential ribs separate the depressions from one another and have a width which is approximately 1/4 to 3/4 of the circumferential dimension of the depressions. The radially outwardly located peripheral surface of the tire is subdivided into several segments. The circumferential dimension of the depressions and of the transverse ribs is constant within each of the segments, and the circumferential dimension of the depressions and of the transverse ribs is different in successive segments.

Abstract: Conveyor belts made of rubber or rubber-like synthetic materials and having textile and/or metallic reinforcing inserts embedded between an upper cover layer and a lower cover layer. In addition to, and independent of, the reinforcing insert, the conveyor belt is provided with an elastically deformable cushioning insert which contains air pockets and is embedded in the upper and/or the lower cover layer.

Abstract: A vehicle wheel having a rigid wheel rim upon which a pneumatic belted tire is mounted. The beads of the tire contain pull-resistant cores, and are secured by a wheel flange against sliding laterally from the seating surfaces. A recess for receiving a tire bead during mounting of the tire is located adjacent to the seating surface on that side facing the rim middle. The seating surfaces are arranged on the inner periphery of the rim adjacent to a radially inwardly extending wheel flange. The base of the recess has a larger diameter than do the seating surfaces. The mantle surfaces of the rim adjacent to the recess are essentially even or smooth supporting surfaces for the tire zenith or crown portion during emergency operation of the tire. The middle portion of the rim, between the mantle surfaces, is also embodied at least partially as a supporting surface for the tire zenith portion during emergency operation of the tire, and the supporting surface lies essentially at the level of the mantle surfaces.

Abstract: A tread configuration for motor vehicle tires, particularly spare tires, with several peripheral rows of essentially V-shaped blocks. The points of the blocks which sequentially follow each other in the peripheral direction of the tire alternately point in opposite directions transverse to the peripheral direction of the tire. Three rows of blocks are provided, and are separated from each other by linearly extending peripheral grooves. The width of the two outer rows corresponds essentially to the axial dimension of a block; in the middle row, the successive blocks are laterally displaced or offset with respect to each other in such a way that the width of this middle row is approximately 1.3 to 1.8 times the axial dimension of a block.

Abstract: An annular sealing element, made of rubber or rubber-like synthetic material, for insertion between rigid surfaces resting upon each other. The sealing element is provided with at least one insert of textile fibers extending essentially transverse to the sealing direction, with the insert being covered by a rubber or synthetic material layer, yet exposed along its inner and outer periphery or surface.

Abstract: A tread configuration for pneumatic vehicle tires, particularly for spare tires, having a large number of depressions which are separated from each other by transverse webs and peripheral webs, and are successively arranged in the transverse and the peripheral directions of the tire. The depressions have an approximately rectangular cross section, and extend transverse to the peripheral direction of the tire. The webs which limit or define the depressions have a width corresponding to approximately 1/4 to 3/4 of the peripheral dimension of the depressions.

Abstract: A belted pneumatic tire having an annular bandage-like reinforcing insert including a cord layer made of pull-resistant threads, strands and the like and extending in the peripheral direction of the tire. The insert extends essentially over the width of the tread between the tread and the carcass. The reinforcing insert includes one or more peripheral segments which are joined together into a ring or annular body having an overlapping area extending at an incline to the peripheral direction of the tire. The overlapping area includes segments rising to the left and right of a center line and joined symmetrically by a V-shaped connection, zig-zag-shaped connection, or wave-shaped connection.

Abstract: A method of producing endless drive belts of natural or synthetic rubber with thread-shaped embedded strength carriers which preferably extend in the longitudinal direction. This method relates especially to multiple V-belts and similar belts having longitudinal ribs extending continuously over the inner periphery or circumference thereof. A raw belt member is built up in upside-down sequence of layering, and is placed into an outer form or mold, in which it is formed-out and vulcanized. The belts are then turned or folded or rolled over into the use condition thereof. The raw belt member, which is produced oversize with respect to the outer form or mold, is retracted, pulled-in, or drawn-in to an outer diameter corresponding to the smallest inner diameter of the outer form, and is expanded within the outer form to, or essentially to, the original outer diameter thereof.

Abstract: A pneumatic vehicle tire with a pull-resistant belt which extends essentially over the width of the tread and essentially stabilizes the tire body against lateral forces. The tire also has a reinforcement in the tire sidewall consisting of cord fabric layers, whereby the externally located cord fabric layer has a greater expansion, elongation, or elasticity than the cord fabric layer which faces or is directed toward the tire hollow chamber. Furthermore, the cord fabric layer of smaller elasticity is guided from bead to bead and is there secured or anchored by being looped around the bead cores. With at least approximately radial positioning of both cord fabric layers of the tire sidewall, the externally located cord fabric layer extends only from one bead to an adjoining tire shoulder, and in this region the edges of this cord fabric layer are arranged between the cord fabric layer which is guided from bead to bead and the edge of the belt.

Abstract: Conveyor belt of rubber or rubber-like elastomeric synthetic materials with strength members embedded in the belt and arranged in mutually spaced apart relationship while extending parallel to each other in the longitudinal direction of the belt, whereby the strength members are generally distributed in groups over the width of the belt at predetermined intervals. The strength members can be in the form of wires, cables, ropes and the like, while the conveyor belt includes carrier elements such as cups, baffle plates, rakes or scrapers, or pusher dogs, and the like.

Abstract: A tread or tread profile, especially for radial tires of trucks and similar vehicles, is disclosed. The tread includes six profile ribs arranged symmetrically to the circumferential center of the tire. Grooves of zigzag or similar wave patterns are provided between the profile ribs. The lateral profile ribs at the shoulders of the tire have a width which is about two times the width of a central profile rib and the pertaining lateral grooves are about 1/3 the width of the central groove. The tire can also be provided with radial recesses in the shoulder of the lateral profile ribs.

Abstract: A pneumatic vehicle tire with a tread strip having wood powder embedded therein and through the tread strip in the form of particles having a size within the range of from about 0.02 to 0.25 mm (mesh width of from 20 to 250.mu. according to German Standards DIN 4188). The wood particles are directly connected to and embedded in the tread strip mixture of which tread strip is made, e.g. rubber mixture, without the employment of adhesives. The wood particles amount to about from 2 to 10% by weight of the tread strip mixture.

Abstract: A pneumatic vehicle tire with at least two tread strips separated from each other by circumferential grooves and including belt-like reinforcements between the tread strips and the radial carcass while each tread strip has associated therewith a belt the width of which substantially corresponds to the width of the tread strips. Within the region of the belts, at least between these belts, there are provided thread-shaped strength carriers which together with the circumferential direction of the tire define an angle within the range of from 0.degree. to 10.degree..

Abstract: A pneumatic vehicle tire having a single layer radial carcass of steel or a material of similarly high strength. The carcass is anchored by being looped around the bead cores in the beads. The laterally outwardly lying free ends of the carcass layer may extend up to about half the height of the tire side walls. Laterally outwardly, next to the looped around carcass end, between the rim flange and this carcass end, there is provided a bead reinforcer which includes pull-resistant threads or the like which are parallel to one another. The bead reinforcer is slanted with regard to the carcass, preferably extending at an angle of about 15.degree. to 45.degree. to the circumferential direction of the tire. The radially outwardly lying free end of the bead reinforcer has associated therewith a strip which extends parallel to said free end and includes pull-resistant threads or the like which are arranged in a cord layer.

Abstract: Apparatus for the replaceable mounting of a winding drum for web-like material. The apparatus includes two supporting carriers which rotatably hold the winding drum at both end faces. The carriers are pivotally mounted about substantially horizontal axes.

Abstract: A method of and extrusion press for producing profiled strands from elastomeric material, especially undulated edges, for conveyor belts, including a linear base and a ridge placed on the base. Portions of the strand change direction along its length. The extrusion press method is used, and different flow velocities are imparted to the elastomeric material at different portions of the cross section of the strand. The extrusion press is equipped with a nozzle plate having profile openings corresponding to the cross sectional shape of the desired profiled strand. On that side which faces the press equipment--including wormgear, piston, and rollers--the nozzle plate is equipped with approach surfaces, which lead to the profile openings at angles inclined to the direction of extrusion, and which have different lengths in different cross-sectional regions of the profile openings.

Abstract: An adhesive printing blanket including rubber or rubber-like material. The printing blanket may also be provided with reinforcing inserts. A foil-like protective layer covers the adhesive layer of the printing blanket. The protective layer, which is elastically flexible, is removed by pulling off prior to the adhesive mounting of the printing blanket. The protective layer is under a tensile stress to preclude creasing during rolling up of the printing blanket into a roll and during subsequent spreading out of the printing blanket into a plane.

Abstract: A vehicle wheel having an annular emergency support arranged within the hollow space of a pneumatic tire mounted on the wheel. The annular support is supported on the rim of the wheel between the two beads of the tire and next to the drop center of the rim by means of a projection located on the inner periphery of the annular support. The projection extends radially inwardly and may be introduced into the drop center to facilitate mounting and removal of the annular support.
