Abstract

A method for forming a cylindrical rubber member includes bringing a dieclose to a forming drum, forming a winding start portion Sby extruding a rubber S and simultaneously starting to rotate the forming drumto gradually increase an extruding amount to an amount Qand gradually increase a distance between the dieand the forming drumto a distance Dcorresponding to a desired thickness of the cylindrical rubber member, winding the rubber S by maintaining the extruding amount at the amount Q, and maintaining the distance between the dieand the forming drumat the distance D, and forming a winding end portion Son the winding start portion Sby maintaining the distance between the dieand the forming drumat the distance Dand gradually reducing the extruding amount from the amount Q
