PISTON RING MANUFACTURING METHOD ABSTRACT OF THE DISCLOSURE A method for manufacturing a piston ring for use in a refrig- erant compressor is disclosed. The method includes the steps of disposing the piston ring in an annular groove which is formed on one end surface of a fixed holder; and pressuring the piston ring in the groove by a lower end surface of a press until the lower end sur- face of the press contacts the upper end surface of the fixed holder. At least one projection formed on either the fixed holder or the press contacts the piston ring. A plurality of grooves are thereby formed on one end surface of the piston ring as the pressing opera- tion progresses.
