Abstract: A process for balancing a rim and tire, which comprises first balancing the rim, then mounting the tire, properly inflating it and balancing a second time to determine the location and weight of balancing required. The tire and rim are then indexed with marks to indicate where the balancing weights should be placed. These indexing marks will be used at the remounting stage to assure proper balancing. The tire is then deflated and removed from the rim and the correct mass rubberized weights are vulcanized to the internal surface of the tire sidewall at the indexing mark and on the opposite sidewall across from the indexing mark. The tire is then installed back on the rim with the indexing marks lined up next to each other. The tire is re-inflated and the balance re-checked with a spin balancing machine.

Abstract: The subject invention relates to a method of preparing a tire inner surface to attain better adhesion of balance pads, puncture sealants, and noise reduction foams. In this method a strip of multi-axially stretchable film is adhered to the inner surface of an uncured tire with a pressure-sensitive adhesive. Then a release agent coating is applied to the film strip on the inner surface of the uncured tire which is subsequently cured in a suitable mold at an elevated temperature. The cured tire is then removed from the mold and after allowing the cured tire to cool the annular circumferential film strip is removed from the inner surface of the tire to provide a circumferential release coating-free tire inner surface onto which balance pads, puncture sealants, and noise reduction foams can be adhered.

Abstract: A method and apparatus for balancing a tire during a retreading operation includes measuring the radial runout the buffed tire casing and applying the gum layer and tread strip to compensate for variances in runout. The gum layer is applied so that an overlap or smear is formed at the relative low portion of the casing.

Abstract: A bond of a rubbery component to a virgin surface of a tire's cured innerliner which virgin surface has never been contaminated by the remnants of a release agent left after buffing with a wire brush and solvent-cleaning the cured innerliner, is unexpectedly stronger than a bond of the component to the contaminated but “cleaned surface”, cleaned as indicated.

Abstract: Effective control of warp in the manufacture of corrugated paperboard sheets on standard corrugator equipment is achieved by the on-line application of a regulated quantity of moisture to one or both sides of the completed corrugated paperboard web after it has been heat-bonded together, while it is still hot from the heat-bonding operation, and prior to its being cut into individual corrugated paperboard sheets. By proper selection of the quantity and placement of the moisture application treatment, it is possible to counterbalance the net effect of the warp-producing conditions developed within the bonded paperboard web prior to and during its bonding operation, so that the resulting paperboard sheets leaving the corrugator will be consistently substantially flat. The moisture application treatment is carried out with an adjustable moisture spray system designed to selectively apply to either or both sides of the bonded paperboard web a variable regulated quantity of moisture.

Abstract: A method and apparatus for correcting imbalance occurring in pneumatic tires during their manufacture. Correction is made by depositing on the inside surface of the tire, at a balance-correcting position, a measured quantity of an uncured, quick-curing, urethane or other liquid elastomer composition which bonds to such surface when cured, and curing the composition in place against the surface. The surface is cleaned in advance, as by washing, scrubbing, and/or abrading, to remove mold release agents and the like and to expose the bare rubber of the tire wall for bonding. The elastomer is desirably deposited in a pool, but may be dispensed in a stream of air or other gas directed toward the deposit. The air reduces the thickness of the pool and feathers its edges and thereby reduces the discontinuity between the deposited material and the tire surface, and promotes bonding.
