摘要： Pressure is controlled in plural stages of a shaping system for a green tire in a curing press, so that each successive shaping stage is completed when a target pressure for that stage is reached. A radial tire is preferably shaped in three stages in the first of which a first target pressure in the range from 2 psig to 5 psig is the desired shaping pressure; in the second stage, a second target pressure in the range from 7-10 psig is desired; in the third stage, a third target pressure in the range from 10-15 psig is desired. A pressure transducer (PT) senses the pressure in a bladder, one PT for each bladder. A programmable controller (PC) which controls operation of the press, stores and executes a sequence of instructions which determine the optimum desired shaping pressure for each stage, computed from the type and size of the tire to be cured, the period of time the press is down before it is loaded, and the number of heats on each bladder. The automatic computation of optimum desired pressure for each shaping stage avoids having an operator set a mean pressure for each stage by trial and error, making such adjustments for change of bladder, and unduly long press down time which in his judgment appear to be reasonably likely to produce a defect-free cured tire.

摘要： Methods for controlling curing apparatuses for tyre production, wherein the curing apparatuses are adapted to work on green tyres to obtain corresponding finished tyres by acquiring, through a processing unit, initial parameters describing at least one of the shape and dimensions of the finished tyres. The processing unit computes first parameters describing the green tyres, the first parameters having at least one parameter representative of an axial height of the green tyres; second parameters describing the curing apparatuses, the second parameters having one or more parameters representative of dimensions of the curing apparatuses; and third parameters as a function of the first parameters and the second parameters, the third parameters having one or more parameters representative of positions taken by movable members included in the curing apparatuses. The processing unit generates signals for controlling the movable members of the curing apparatuses.

摘要： Systems and methods for improving tire uniformity through identification of transient effects contributing to the non-uniformity of a tire are provided. More particularly, uniformity measurements can be obtained for a set of a plurality of tires. The uniformity measurements can include contributions from tire harmonic uniformity effects (e.g. effects attributable to tooling elements used during tire manufacture) as well as process harmonic uniformity effects (e.g. effects attributable to process elements used during tire manufacture). Certain of the tire harmonic uniformity effects can be transient effects that change from tire to tire. For instance, the effect attributable to a curing membrane used during the curing process can transiently change from tire to tire. Aspects of the present disclosure are directed to identifying transient effect contributions to uniformity measurements and improving the uniformity of the tire using the identified transient effect contributions.

摘要： In a vulcanizing system of the present invention, a temperature booster and a pressure booster are provided on a steam supply path connecting vulcanizers that belong to groups and a boiler allocated to the groups. The temperature booster and the pressure booster are sequentially arranged from an upstream side, a second branch supply path for supplying the steam to a mold between the temperature booster and the pressure booster is branched from the steam supply path. The second branch supply path is preferably in a form of allowing the steam temperature-boosted by the temperature booster to be supplied to the mold by bypassing the pressure booster.

摘要： A vulcanization apparatus provided with a vulcanization vessel for vulcanizing a green tire and a suction line for sucking out gas from inside the vulcanization vessel after the vulcanization vessel has been opened. Accordingly, oily smoke generated when vulcanized rubber has been removed from a bladder and an inner wall of a mold can be more efficiently discharged than in cases in which gas inside a vulcanization vessel is sucked out and additional air is introduced into the vulcanization vessel only prior to opening the vulcanization vessel.
