Zusammenfassung: | PURPOSE:To make a spacer expander and the like having a slip joint insertable into a ring groove in an automated manner, by installing a supporting claw supporting a guide jig. CONSTITUTION:A guide jig 3 guiding and expanding a piston ring 8 fed out by a cutting plate 7 has a cylindrical part 31 guiding the piston ring 8 and also a conical part 32 expanding the piston ring 8. In addition, it has each of supporting claws 5 supporting the guide jig at the circumferential line position of the guide jig 3 from the peripheral side. Then, a lifter 9 supporting a pressure cylinder which pushes out the piston ring 8 in a direction toward a piston, and the guide jig 3 from underside via a piston 89 is installed. Therefore, a spacer expander having a slip joint and a multi-winding piston ring as well as even such a piston ring whose fitting notch is closed are all made insertable into a piston- ring groove in an automated manner. |
