  • Method for processing rubber granules or rubber powders
    Patent number: 9221060
    Abstract: A method for processing rubber granules or rubber powders containing different types of rubber. Vehicle tires containing natural rubber in the tread and butyl rubber in the inner liner are granulated or ground to prepare rubber granules or rubber powders, which are processed in a flotation cell under stirring and with the addition of air. The natural rubber fraction of the rubber granules has a higher tendency to adsorb air bubbles and to rise in the flotation cell, while the butyl rubber fraction remains at the bottom. The rubber granules are separated into two or more rubber fractions with an increased amount of a specific rubber type in each fraction.

  • Sulfur-crosslinkable rubberizing mixture
    Patent number: 9217077
    Abstract: A sulfur-crosslinkable rubberizing mixture for strengthening elements in motor vehicle pneumatic tires comprises 70 to 100 phr (parts by weight, based on 100 parts by weight of total rubbers in the mixture) of natural rubber, up to 30 phr of at least one polybutadiene, 40 to 70 phr of at least one carbon black and a bonding system. Further, motor vehicle pneumatic tires are disclosed that comprise the sulfur-crosslinked rubberizing mixture. The key conflict between tear propagation resistance, stiffness and heat build-up is solved by virtue of the carbon black being a nanostructured carbon black with a rough surface.

  • Pneumatic vehicle tire with tread having circumferential grooves having projections
    Patent number: 9168792
    Abstract: A pneumatic vehicle tire has peripheral grooves with outer edges on a tread periphery, running peripherally parallel and substantially linearly. A groove base path on a groove base is wavy or zigzags and narrower than a peripheral groove. Projections of groove sides assigned to inward pointing corners of the groove base path are parts or sections of bodies with a base surface having at least four free sides. The base surface runs near the periphery at an angle of at least 60° and is inclined to the radial. The base surface has boundary surfaces running from the free sides toward the groove base at a smaller angle and being inclined to the radial. Two side surfaces run between adjacent projections in peripheral direction, toward the groove base path and have an angle of inclination to the radial larger than the boundary surface angle and smaller than the base surface angle.

  • Sulfur-crosslinkable rubberizing mixture
    Patent number: 9150714
    Abstract: A sulfur-crosslinkable rubberizing mixture for strengthening elements in motor vehicle pneumatic tires comprises 70 to 100 phr (parts by weight, based on 100 parts by weight of total rubbers in the mixture) of natural rubber, up to 30 phr of at least one polybutadiene, up to 15 phr of at least one carbon black, 20 to 100 phr of at least one high-dispersibility silica, at least one silane coupling agent and a bonding system. The invention further relates to motor vehicle pneumatic tires comprising the sulfur-crosslinked rubberizing mixture. For improved resistance to cracking and growth of cracks with good adhesion and good mechanical and dynamic properties, the high-dispersibility silica has a CTAB number to ASTM D 3765 of more than 130 m2/g.

  • Pneumatic vehicle tire with specified bracing plies and bracing bandage
    Patent number: 9132703
    Abstract: Pneumatic vehicle tire includes at least two bracing plies arranged to intersect each other at an angle and including reinforcements of steel arranged substantially parallel to and at a distance from one another and embedded in a rubber material. Bracing ply reinforcements are oriented at an angle of 18° to 45° with the circumferential direction of the tire. A bracing bandage is also included having at least one ply with reinforcements of a non-metallic material arranged substantially parallel to and at a distance from one another and generally extending a circumferential direction of the tire. Bracing bandage reinforcements include a material with heat shrinkage properties. Under a predetermined extension of 1% in the longitudinal direction of the reinforcements, each bracing ply, has a tension of <17,500 N per dm of width, and the bracing bandage as a whole has a tension of >2,000 N per dm of width.

  • Pneumatic vehicle tire
    Patent number: 9132701
    Abstract: A vehicle pneumatic tire for utility vehicles includes a carcass (5), a belt (9) and a profiled tread (10), wherein the belt (9) has three belt layers (13, 14, 15). The radial inner (13) and the radial outer (15) belt layers are working layers having reinforcements (23, 25) made of steel. The belt layer (14) is arranged between the two working layers (13, 15) and is a belt layer configured as a zero degree layer. The two working layers (13, 15) are wider than the belt layer (14) and are coupled to each other in the axial direction outside of the belt layer (14) at a length (p) of p>0 mm so that the distance (s) of the reinforcement (23) of the one working layer (13) to the reinforcement (25) of the other working layer (15) is given as s<1.5 mm.
