  • Patent number: 4770736
    Abstract: An apparatus has a rotary member mounted to it for rotating around a fixed axis of rotation, and also has a support member secured to it to extend tangential to the rotary member, the location of tangency being defined as a workstation. A continuous first medium extends around substantially the whole periphery of the rotary member. The first medium moves relative to the periphery due to a mechanism on the rotary member which continuously withdraws a portion of the first medium from the periphery and replaces that withdrawn portion with a new portion. The first medium is thereby pulled along the periphery of the rotary member in the same direction in which the rotary member is adapted to rotate. A second medium moves along the support member and through the workstation at the same speed as that at which the first medium passes through the workstation.

  • Patent number: 4770733
    Abstract: Product and process for heat transfer labeling. A transfer layer containing a design print is superimposed upon a contoured release layer that is desirably imprinted on a carrier. When the carrier, together with the release layer and the transfer layer are applied to an object to be labeled and heated, both the release layer and the transfer layer become molten and the transfer layer becomes adhered to the object being labeled. The release layer and the transfer layer are immiscible when in a molten state. The desired immiscibility can be acheived by the inclusion of a barrier layer between the transfer layer containing the design print and the release layer.

  • Patent number: 4768575
    Abstract: A pneumatic tubeless tire is produced in such a way that the tire cord fabric (also known as the tire carcass fabric or ply fabric) has the ends thereof secured during tire building so that separation of the cord fabric ends, and a resulting blemish, does not occur. The carcass fabric is wrapped around a rubber inner lining body with turned up portions of the carcass fabric at a pair of beads on opposite sides of the body, during tire construction. The free ends of the carcass fabric are butted together around the body, to provide a butt seam. The free ends are held together in substantial butting position by placing an open mesh warp knit splicer fabric highly extensible in both the machine and cross-machine directions over the butt seam and affixing the splicer fabric in place using adhesive or the like. Rubber tack may be applied over the splicer fabric. The open mesh fabric appears to have no machine direction or cross-machine direction yarns, but only bias yarns.

  • Patent number: 4767480
    Abstract: An apparatus and method for cold retreading or recapping of the running surface of a vehicle tire. A rubber, rope and cloth sectioned mold is produced utilizing a new tire male mold covered with perforated polypropylene film, uncured rubber with nylon rope at its edges and highly stretchable cloth enclosed in an envelope and cured by application of pressure and heat. A male mold is used to make the final female mold directly, or to make an intermediate mold which is used to produce a tread ring that is stretched to form a larger diameter male mold from which a final mold is prepared. The final mold is then sectioned to form one discontinuous section or two or more sections. Conveniently, one section from one size tire may be fitted with a section or sections from other size tires to form a mold to recap a third size tire. Additionally, radial inserts having the radial cross sections of the mold sections may be added to accommodate various tire sizes.

  • Patent number: 4765854
    Abstract: A method of sequentially producing a plurality of disposable headdresses in which the edge of the cap fabric has been folded inward around a peripherally extending elastic cord to provide a smooth edge which contacts the wearer, and provides superior adhesion between the elastic cord and the cap fabric by utilizing an elastic cord and fabric which are coated with or made of thermoplastically compatible materials. The elastic cord and fabric are assembled by passing the fabric and the cord through a guide system which turns the fabric side edges down from a horizontal plane to a vertical plane while an edge guide lays the elastic cord under the fabric, and then turns the fabric under the cord to sandwich in the folded edge. Warm air preheaters heat the elastic cord and the fabric before completing the fabric fold around the cord. The folded edges with the cord inside pass between dual heat wheels which physically press the fabric to the cord and also seal the fabric edge to the inside of the crown.

  • Patent number: 4765384
    Abstract: A pneumatic vehicle tire for trucks, especially for the drive axles thereof. In the region of the edges of the tread, the tire has circumferential rows of blocks separated by grooves that open freely to the sides. Provided to both sides of the laterally outwardly disposed rows of blocks is a practically cylindrical surface. In order to increase the capacity of the shoulder regions of the tire to withstand dynamic stresses, and also in order to increase the support surface of the tire upon soft ground, the base of the aforementioned grooves merges in a stepless manner with the lateral cylindrical surfaces. Advantageously, the laterally outwardly disposed edges of those blocks that form the edges of the tread merge with steep side surfaces that are disposed perpendicular to the cylindrical surfaces.

  • Patent number: 4763709
    Abstract: The present invention discloses a system for varying the inflation pressure in the tires of a vehicle in order to obtain an operator selected tire deflection. The system includes a source of pressure which is fluidly connected through an inflation valve to the tires which, upon actuation, increases the tire pressure. Conversely, a deflation valve is also connected to the tire and, upon actuation, exhausts fluid from the tires thus decreasing the tire pressure. A pressure sensor detects the pressure representative of the pressure within the tires and a further sensor detects the vehicle load while a switch arrangement allows the operator to select between at least two different tire deflection levels. An electronic control unit receives input signals from the pressure and further sensors as well as from the switch arrangement and selectively actuates the inflation or deflation valves until a tire pressure corresponding to the desired tire deflection is obtained.
