A rolling apparatus is capable of rolling a metal ring to an accurate circumferential length and preventing the metal ring from dropping off. The rolling apparatus includes a metal ring support assembly having tension rollers 2a, 2b for supporting a metal ring W, a rolling roller 5 for rolling the metal ring W, a rolling assembly for pressing the rolling roller 5 against the metal ring W, a tension applying assembly having a tension cylinder 23 engaging tension roller support members 8, 10, 25, on which one of the tension rollers 2b is rotatably supported, for displacing the tension roller 2b to apply tension to the metal ring W, and a rolling processing completing assembly 27 for detecting a completion of rolling of the metal ring W and inactivating the rolling assembly and the tension applying assembly. The rolling assembly has a first resilient member 18 interposed between the rolling cylinder 5 and its piston rod 15. The tension applying assembly has a second resilient member 28 interposed between a piston rod 24 of the tension cylinder 23 and the tension roller support member 25. <IMAGE> |
