Patent number: 4266349Abstract: A continuous outsole for a sports shoe has a profile pattern characterized by a first large circular pattern section at the area of the ball of the foot and a second large circular pattern section at the heel area. Each large circular pattern section has a center point that is disposed substantially on a longitudinal dividing line that extends from an end of the toe portion to an end of the heel portion and divides the outsole into two substantially equal longitudinal areas.Type: GrantFiled: November 17, 1978Date of Patent: May 12, 1981Assignee: Uniroyal GmbHInventor: Michael W. Schmohl

Patent number: 4227563Abstract: A heavy duty pneumatic tire is provided with bead cores of symmetrical or asymmetrical polygonal cross-sectional. Extending radially outwardly therefrom are apex strips of a hard rubber compound which contact the bead cores along their radially outwardly oriented faces. The apex strips have a width at least as great as the width of the bead cores measured in a selected direction, and have a height of not more than 1.5 times the width of the bead cores. The terminal ends of turnups formed by wrapping a carcass ply radially about the bead cores, and reinforcement strips are enveloped in cushion elements of a rubber material which are softer than the carcass ply and the apex strips. The apex strips have a markedly compact shape cross sectionally and form with the bead cores, rigid units through which stresses occurring in the carcass during tire operation can be transferred.Type: GrantFiled: March 29, 1978Date of Patent: October 14, 1980Assignee: Uniroyal GmbHInventors: Karl Grosch, Paul Moitzheim, Gert Schloesser

Patent number: 4216814Abstract: A heavy duty pneumatic tire is provided with bead cores having polygonal cross-sectional configurations. The bead cores are composed of a multiplicity of wires arranged in densely superpositioned parallel layers which are situated on conical generating lines whose common axis coincide with the horizontal axis of the pneumatic tire and whose angles of opening are approximately 10.degree.. The axially innermost and axially outermost wires in specified radially inner and radially outer layers lie on centerlines forming angles within selected ranges with the conical lines.Type: GrantFiled: April 20, 1978Date of Patent: August 12, 1980Assignee: Uniroyal GmbHInventors: Karl A. Grosch, Henri J. Mirtain, Andre M. Devienne, Jean Trzepaez

Patent number: 4183389Abstract: A heavy duty pneumatic tire includes a carcass having a crown region and a tread portion surrounding the crown region. A reinforcement belt is disposed circumferentially about the crown region between the carcass and the tread. The reinforcement belt includes a first ply of tire cord fabric with two free lateral edge portions folded over upon itself to form two skirts and a main portion. The cords in the first ply are steel and lie at an angle of from about 16.degree. to about 32.degree. with respect to the equatorial plane of the tire. A second ply of tire cord fabric is superimposed upon the first ply. The cords in the second ply are of textile composition and are disposed at an angle of substantially 0.degree. with respect to the equatorial plane of the tire. The second ply fetters or restrains the first ply onto the carcass and imparts to the carcass a substantially flat cross-sectional configuration in the crown region.Type: GrantFiled: April 11, 1978Date of Patent: January 15, 1980Assignee: Uniroyal GmbHInventor: Karl A. Grosch

Patent number: 4166490Abstract: A pneumatic radial tire in which the oblique pulling effect due to the structure of the tire is substantially eliminated and which has substantially improved stability in maintaining a rectilinear course. The tread has circumferentially oriented rows of lugs oriented along intersecting convexly curved approximately V-shaped reference lines running substantially transversely to the circumferential center line. The tips of the reference lines point in opposite directions on either side of the circumferential center line.Type: GrantFiled: May 24, 1977Date of Patent: September 4, 1979Assignee: Uniroyal GmbHInventor: Dionysius J. Poque

Patent number: 4135566Abstract: Belted pneumatic tire having a reinforcing textile layer disposed between the tread and the carcass. The reinforcing textile layer can be transversely continuous or discontinuous across the crown region of the tire and extends into the shoulder areas. In the shoulder areas the reinforcement is a plural layer formed by a folding over of the textile. The tire may include a metallic breaker located above or below the textile reinforcement. The folded portion of the textile extends beyond the marginal edges by the metal breaker. The cords of either the textile or metal layers can be oriented at zero degrees to the equatorial plane of the tire.Type: GrantFiled: June 16, 1977Date of Patent: January 23, 1979Assignee: Uniroyal GmbHInventors: Gerhard F. Senger, Dionysius J. Poque

Patent number: 4135565Abstract: A pneumatic tire having a radial carcass and at least two plies of steel cord belts as constituents of the reusable tire body has recap components that include an unvulcanized reinforcement belt having rubberized textile cord elements oriented parallel with respect to the equatorial plane of the tire. The textile cord reinforcement belt is wound around the tire under tension and an unvulcanized tread strip is applied thereover. Subsequent vulcanization assures a firm bond between the recap components and the used tire body.Type: GrantFiled: November 29, 1976Date of Patent: January 23, 1979Assignee: Uniroyal GmbHInventor: Sjirk van der Burg
