PROBLEM TO BE SOLVED: To provide a production method for a pneumatic tire, sufficiently restraining a joint defect, occurrence of dent or uniformity deterioration in a product tire by cutting a carcass cord without damaging when cutting a long carcass ply, substantially preventing a fractured cutter blade from mixing in the tire and capable of reducing a production cost, and to provide a cutting device for the carcass ply.SOLUTION: There is provided a production method for a pneumatic tire using a carcass ply which is molded in a cylindrical shape by cutting a long carcass ply coating the arrangement body of carcass cords with a rubber into a prescribed length and winding on a molding drum. The long carcass ply is cut by moving a stretched yarn from one side edge part of the long carcass ply toward the other side edge part along the carcass cord.SELECTED DRAWING: Figure 1

    【課題】長尺のカーカスプライを切断する際、カーカスコードを損傷させることなく切断して、製品タイヤにおけるジョイント不良やデントの発生およびユニフォミティの悪化を十分に抑制すると共に、折れたカッター刃のタイヤへの混入を十分防止し、さらに、コストの低減を図ることができる空気入りタイヤの製造方法およびカーカスプライの切断装置を提供する。【解決手段】カーカスコードの配列体をゴムで被覆した長尺のカーカスプライを所定の長さに切断して、成形ドラムに巻回すことにより円筒形状に成形したカーカスプライを用いて空気入りタイヤを製造する空気入りタイヤの製造方法であって、張設された糸を長尺のカーカスプライの幅方向の側縁部から他方の側縁部へ向けてカーカスコードに沿って移動させることにより、長尺のカーカスプライを切断する空気入りタイヤの製造方法。【選択図】図1
