PROBLEM TO BE SOLVED: To provide a cleaning method for an innermost surface having residual deposits on the innermost surface of a pneumatic tire.SOLUTION: This method comprises: a step of activating laser to generate laser radiation; a step of striking laser radiation pulses onto a region of the innermost surface, where laser radiation pulses have pulse widths and fluences enough to form a purified region by removing at least a part of residual deposits 12 of the region; and a step of repeating the step of continuously directing radiation pulses to the innermost surface to form a series of purified regions, where the series of purified regions define a stripe 14, the stripe tracks a continuous non-linear path extending in the circumference of at least one of the inner surface, and the stripe has a stripe width.SELECTED DRAWING: Figure 1

    【課題】空気入りタイヤの最内表面上に付着残留物を有する最内表面のクリーニング法を提供する。【解決手段】方法は、レーザーを活性化してレーザー放射線を発生させる工程;レーザー放射線のパルスを最内表面の領域に向けて当てる工程、ここで放射線のパルスは、領域の残留物12の少なくとも一部を除去して浄化領域を形成するに足るパルス幅及びフルエンスを有する;および放射線のパルスを連続的に最内表面に向ける工程を繰り返して一連の浄化領域を形成させる工程、ここで一連の浄化領域はストライプ14を画定し、そのストライプは内表面の少なくとも一つの周囲に延びる連続した非線形経路を辿り、そのストライプはストライプ幅を有するを含む。【選択図】図1
