  • Patent number: 4798236
    Abstract: A high performance tire, in which a plurality of narrow cuts are disposed on both shoulder parts where heat generation is most notable, to control the heat generation by decreasing the pattern stiffness. The slippage of tread rubber is prevented due to improved grounding performance of both shoulder parts, so the high-speed durability and the stepped shoulder wear are improved in spite of the extra heavy tread with deepest longitudinal main grooves. At the same time, wear life of the tread, wandering performance including wet grip performance, ride feeling and handling stability can effectively improved in a well-balanced manner.

  • Patent number: 4794968
    Abstract: A tire is disclosed, including a tread portion, sidewalls and a pair of beads each containing a substantially inextensible annular bead core, having a bead seat and an extended toe portion. The extended toe portion includes an elastomeric material, extending lengthwise from the bead core in a direction radially and axially inwards thereof, the toe of a rigidity in the direction of its length such that in use of the tire on a wheel rim having a groove complementary to the toe and engaging the toe when an axially inward force is applied to the tread portion, a radially and axially outwardly directed force is generated at the bead core to affect bead retention. The toe has a substantially continuous, circumferentially extending toe decoupling means at the junction of the tire bead seats and the toe so that the toe is effectively decoupled from the bead in bending of the toe axially inwards of the tire. The decoupling means may be a single cut of a small groove.

  • Patent number: 4791971
    Abstract: A pneumatic tire, particularly for tractors or other like vehicles, having a tread portion containing alternating, spaced-apart short and long lugs proceeding axially inward from a lateral tread edge, and an identical (but opposite in hand) set of long and short lugs proceeding axially inward from the other lateral tread edge and offset circumferentially so that a long lug emanating from one lateral edge is opposite a short lug emanating from the other lateral edge. The lugs are smoothly curved axially inward in the direction of intended tire rotation to provide excellent traction while minimizing vibration.

  • Patent number: 4790898
    Abstract: A series of filaments are grouped into rovings (10), with each roving being impregnated with a viscous, tacky resin binder. The rovings are guided (12, 14, 16) to and compressed against a mandrel (18). By controlling intraroving spacing and compression force, the rovings are compressed such that their lateral expansion results in adjacent roving bonding, whereby a singular band (22) of defined width, height and filament count is formed. The height and width is controlled by varying the compression force and the intraroving spacing. Band contouring is realized by severing (24, 26) selected rovings prior to band formation. Linear and rotational relative motion is provided (FIG. 11: 110, 112, 114) between the roving guiding and compression means and the mandrel to precisely orient the band.

  • Patent number: 4785861
    Abstract: A high performance tire, in which the profile of radially outer ground contacting tread surface is radially outwardly expanded at both shoulder parts when the tire is inflated, and the tread pattern circumferential stiffness as well as index of groove volume is optimized so that resistance in wear, durability to high speed running (low degree of heat generation), resistance to cutting, and resistance to rolling (low fuel consumption) including wet grip performance and stability in vehicle driving may be advantageously improved without reducing comfortableness in vehicle riding.

  • Patent number: 4782876
    Abstract: A vehicle wheel has at least two pneumatic tires mounted side by side on a single rim. When the weight of the vehicle is applied to the wheels, the pneumatic tires are slightly deformed in the lower portion of their circumference, their facing side walls coming to bear one against the other. In the upper portion of their circumference, the pneumatic tires remain separated from one another. This provides the best possible cooperation of the pneumatic tires, completely avoiding the overheating thereof and improving the road-holding of the vehicle and the adhesion of the wheels on a slippery road surface.

  • Patent number: 4773459
    Abstract: In a pneumatic low section tire with an aspect ratio (height/width) of 0.65 or less, when a green tire is pressurized with a bladder within a mold, tread rubber is forced to flow into recesses for forming a tread block pattern. With this rubber flow, the belt is subjected to deformation toward the same recesses, so that the belt layer deforms outward at the middle of the transversal grooves between two main circumferential grooves. This deformation causes the skid base rubber existing between the transversal groove bottom and the belt layer to be thin at the middle of the transversal grooves, thus resulting in an early trouble. To overcome this problem, the transversal grooves are formed in raised bottom or corrugation fashion along a longitudinal direction thereof, to obtain a uniformly thick skid base. Further, this raised bottom serves to increase the drainage effect during rainy weather running.

  • Patent number: 4773959
    Abstract: An improved means is disclosed for continuously forming tiles that are embossed in register with a printed design. A printed design is first applied to a base coat and a wear coat is laminated over the design. Advantageously, the wear coat is applied to the printed web before it is heated for lamination. Before embossing occurs, the laminated product is cooled until partial setting occurs, and the embossing roll is sprayed with water in order to minimize the likelihood that the laminated product will adhere to the embossing roll. To avoid distorting the web during lamination and embossing, proper web tension is maintained by controlling the rotational speeds of the laminating drum and the embossing roll so that a desired ratio is preserved. The web is then cut into oversized tiles that shrink to size during annealing.

  • Patent number: 4772354
    Abstract: A solvent applicating roll, mounted for rotation about its vertical axis for transferring a solvent from etched or gravure areas on the roll surface to plastic labels that are moved into rolling contact with the roll, has its temperature controlled. The roll is formed as a hollow cylinder with heated air fed to the interior thereof to heat the roll to keep the solvent at a working temperature and prevent evaporative cooling of the roll due to solvent evaporating from the surface during operation. The heated air is passed through a distributor that assures the heated air will effectively transfer its heat to the metal roll.
