To provide a rubber member molding method for smoothly discharging air between a step of a rubber member and a ply material, and a pressing roller used therefor.SOLUTION: A rubber member molding method comprises the steps of: forming a joint portion 12 having a level difference F while winding a rubber member G on a drum 2; winding a ply material P on an outer side in a radial direction of the joint portion 12; and bringing the ply material P into close contact with the level difference F. The joint portion 12 is formed by stacking a winding end Ge of the rubber member G on the outer side in the radial direction of the rubber member G wound on the drum 2. In the step of closely contacting, a pressing roller 3 is rolled on the ply material P from one end side to the other end side in the drum axial direction.SELECTED DRAWING: Figure 4 【課題】ゴム部材の段差とプライ材料との間の空気をスムーズに排出するゴム部材成形方法、及びこれに用いる押圧ローラの提供。【解決手段】ゴム部材成形方法は、ゴム部材Ｇをドラム２上に巻き付けつつ、段差Ｆを有する接合部１２を形成する工程と、接合部１２の半径方向外側に、プライ材料Ｐを巻き付ける工程と、プライ材料Ｐを段差Ｆに密着させる工程とを含んでいる。接合部１２は、ゴム部材Ｇの巻き付けの終端Ｇｅを、ドラム２上に巻き付けられたゴム部材Ｇの半径方向外側に重ねて形成される。密着させる工程は、押圧ローラ３をプライ材料Ｐ上でドラム軸心方向の一端側から他端側に転動させる。【選択図】図４
