ABSTRACT:
An arc-like formed product, such as bearing metal, is manufactured from a strip of sheet metal, by introducing the metal strip in a tangential direction to a cylindrical forming surface of a die, bending and rolling the metal strip along the forming surface of the die into an arc shape, cutting both ends of the formed metal strip at both ends of the forming surface of the die while pressing the metal strip against the forming surface of the die in a range of at least 1/20 to 1/3 of its length, transferring the formed strip piece of metal into a coining die and coining the same.
