Abstract (en)
[origin: EP1987922A2] Ring-forming tool (1) for closing a ring (19), which comprises a top piece (2), a bottom piece (3), a top claw (4) and a lever (9), connected together by means of four pivot points (7, 8, 17, 18), three of which present a fixed position and one of which presents a variable position that enables the tool (1) to vary the lever arm and therefore vary the force exerted on the ring (19) for a same force exerted by the user. In this way, the inventive tool may provide decreasing forces on the ring (19) as the ring (19) closes and offers less resistance.
