Abstract

PURPOSE: To accomplish accurate and smooth molding of the sealing peripheral surface with molding roller provided corresponding to a profile roller by maintaining the running speed of the roller rotating in contact with a profile cam at a constant level.
CONSTITUTION: When driven by a motor 6, a drive shaft 3 is rotated at a constant speed, a rotary disc 9 turns at a constant speed, thus allowing a profile roller 18 to rotate in contact with the cam surface of a profile cam 24. As the cam surface of the profile cam is formed in a shape matching that set for the finishing of the sealing peripheral surface S, a molding roller 20 rotates in contact with the peripheral surface S, finishing thereof in a shape corresponding to the cam surface of the profile cam 24. With proper movement of a correction roller 14, the profile roller 18 can invariably roll on the side of the cam surface at a constant speed.
