A method and apparatus for rapid heating of calender rolls for a calendering apparatus is disclosed. At a heating area , the rolls are preheated, reheated, or maintained at any temperature prior to the rolls being placed into the calendering apparatus . The preferred method of heating is by induction heating. The rolls may be delivered to the heating apparatus from an initial storage area or the calendering apparatus . The rolls are transported by an overhead transfer mechanism . The disclosed method and apparatus greatly facilitate formation of multi-layered laminates and is particularly useful in the tire building art.

Heating of calender roll surfaces

A tire ( ) has a composite ply ( ). The composite ply ( ) has a primary ply ( A) reinforced with parallel inextensible cords ( ) and a pair of ply extensions ( B) having synthetic cords ( ). The method of manufacturing the tire ( ) is described. The tire ( ) can be made as a runflat type tire.

Composite ply structure for tires and method of manufacture

A rubber tire component ( ) is laden with a mixture of fibers ( ). The fibers ( ) being sensitive to induction heating can be rapidly cured using a variety of methods. The preferred method permits a selective induction curing of the fiber laden component ( ) in combination with conventional curing presses.

Induction curable tire components and methods of selectively curing such components

A method for minimizing the radial runout of a tire and rim assembly,having the steps of locating the position of maximum radial runout and measuring the amount of maximum radial runout; loosening the threaded fasteners,attaching the rim,and disk,; and moving the disk,radially toward the location of the maximum radial runout a distance one-half the measured runout amount and then retightening the threaded fasteners is disclosed. The method minimizes first harmonic vibrations caused by the normal assembly of these components.
