    • PROBLEM TO BE SOLVED: To grind a tire to be recapped by a grinding means so that the thickness of the residual rubber on the outer peripheral side of the belt layer in the tire to be recapped even in a case that eccentricity is caused in the tire to be recapped with respect to the axis of a grinding apparatus of a tire. SOLUTION: In the grinding apparatus 10, first, the distance from an eddy current sensor 44 to the outer peripheral surface of the belt layer 104 is detected by the eddy current sensor 44 with rotating the tire 100 to be recapped held by a pair of half rims. By this method, since the quantity of eccentricity and an eccentric direction can be calculated with respect to the axis of the grinding apparatus of the tire 100 to be recapped corresponding to the phase of the tire 100 to be recapped, a position control signal corresponding to the phase, quantity of eccentricity and eccentric direction of the tire 100 to be recapped can be formed. Subsequently, a rasp 62 is moved in the diametric direction of the tire 100 to be recapped on the basis of the position control signal along the diametric direction centering around the axis MC of the grinding apparatus by a carriage 58 and the tread surface of the rotated tire 100 to be recapped is ground by the rasp 62.

    • 要解决的问题:为了研磨由研磨装置重新覆盖的轮胎,使得即使在引起偏心的情况下轮胎中的带束层的外周侧上的剩余橡胶的厚度也被重新涂覆 在轮胎中相对于轮胎的研磨装置的轴线重新盖上。 解决方案:在研磨装置10中,首先,涡流传感器44通过旋转轮胎100来检测从涡流传感器44到带束层104的外周面的距离,以将轮胎100重新保持在 一对半边缘。 通过该方法,由于可以相对于要重新轮胎的轮胎100的相位而重新计算的轮胎100的磨削装置的轴线来计算偏心量和偏心方向的位置控制信号, 可以形成轮胎100的重新配置的相位,偏心量和偏心方向。 随后,在轮胎100的直径方向上移动锉刀62,沿着沿着研磨装置的轴线MC的直径方向的位置控制信号通过滑架58进行再生,并且旋转的胎面 轮辋100被重新打磨被锉刀62研磨。版权所有(C)2007,JPO&INPIT
