  • Patent number: 10994578
    Abstract: The present invention provides a method for improving the construction process of a wide-base radial truck tire, and the improvement of the tire construction process is realized by the design of carcass ply, the tire belt drum and the tire semi-finished components. The invention solves the problem of carcass bending, and provides theoretical guidance and technical support for improving the performance of wide-angle radial tires. The design method of the belt drum of the tire molding machine effectively controls the cords elongation of the belt. In addition, the problem of uneven force in the cords of the belt is eliminated, which dispels the abnormal flow of the wide-base tire shoulder rubber to the center of the crown during the shaping process, thus improving the durability and operability of the tire.

    Abstract: An apparatus for attachment to a portable image capture and storage device. The apparatus includes an auxiliary lens and an elastic band coupled thereto. The auxiliary lens is shaped for image alteration of an image obtained by the portable image capture and storage device. The auxiliary lens characterized by an optical axis extending from a base of the lens to a crown of the lens. The elastic band extends, at least in part, in a lateral direction, substantially orthogonal to the optical axis, from the auxiliary lens. The elastic band in combination with the auxiliary lens forms a closed loop whereby the apparatus is removably attachable to a peripheral portion of the image capture and storage device to alter the appearance of the image obtained by the portable image capture and storage device.

  • Patent number: 8852371
    Abstract: A method of forming an air passageway in a an air maintenance tire carcass includes: embedding an elongate strip within a pre-cured flexible tire component of a pre-cured tire carcass, the elongate strip extending in a longitudinal direction between an air inlet cavity and an air outlet cavity in the flexible tire component; curing the pre-cured tire carcass including the flexible tire component; extracting the elongate strip longitudinally end-to-end from occupancy within the flexible tire component; and defining an air passageway in the flexible component by the space previously occupied by the withdrawn elongate strip. A free end portion of the strip is accessible at either the air inlet cavity or the air outlet cavity, and the elongate strip may be extracted from either the air inlet cavity or the air outlet cavity by a tensile withdrawal force applied to the elongate strip free end.

  • Patent number: 8815034
    Abstract: A pneumatic radial tire includes: at least one carcass layer suspended across left and right bead parts; a belt layer arranged on an outer circumferential side of the carcass layer; and a tread arranged on an outer circumferential side of the belt layer. The tread has a laminated structure in which a thermoplastic film layer of a thermoplastic resin or a thermoplastic elastomer composition is interposed between a tread-side rubber layer and a belt layer-side rubber layer. The thermoplastic elastomer composition is obtained by blending an elastomer in a thermoplastic resin. A process for producing a retreaded tire includes the steps of: forming a base tire from the pneumatic radial tire by softening the thermoplastic film layer through heating so as to separate and remove the tread-side rubber layer, the pneumatic radial tire having the tread worn away; and subsequently bonding a new tread-side rubber layer onto the base tire.
