Title:
【発明の名称】ラジアルタイヤの製造方法
Document Type and Number:
Japanese Patent JP3362883
Kind Code:
B2
Abstract:
PURPOSE:To reduce sufficiently force variation in a radial direction of each tire. CONSTITUTION:In an RRO waveform measuring process an RRO waveform of each green tire 10 is extracted. In a vulcanization factor waveform recording process a vulcanization factor waveform of a vulcanization mold 20 is recorded in a storage element 16A of a computer 16 every vulcanizer among a plurality of vulcanizers. In a selection process, the RRO waveform of the green tire 10 is superimposed on the vulcanization factor waveform of the vulcanization mold 20 to make a composite wave, and the composite wave which minimizes an RRO waveform amplitude of a vulcanized tire is selected. In a marking process, a superimposed angle theta of the green tire 10 wherein the RRO waveform amplitude of the vulcanized tire is minimized is determined to a peripheral standard position of the vulcanized mold 20 based on the selected composite wave. A mark 28 is marked at a specific position on a periphery of the green tire 10 with a marking device 26. In a vulcanization process, the mark 28 marked in the marking process is fitted to a stencil position 20A of the vulcanized mold 20, and the green 10 is arranged in the vulcanization mold 20 to be vulcanized.
