Abstract
PURPOSE: To reduce the weight of an oil seal ring by forming cut-off parts in the cylindrical part of a conventional metal ring for oil seal processed through a special dimentional setting about the outside punching dimension, strip width and material transporting pitch.
CONSTITUTION: The width B' of a material strip and material transporting pitch P' are chosen small in proportion to the outside punching dimension D0. Cut-off parts 7 are formed each in the shape of a circular arc at the end of the cylindrical part of each ring. According to this manufacturing method, material for the manufacture of oil rings can be saved and their weights can be reduced.
