ABSTRACT:
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 rollers2a, 2bfor supporting a metal ring W, a rolling roller5for rolling the metal ring W, a rolling assembly for pressing the rolling roller5against the metal ring W, a tension applying assembly having a tension cylinder23engaging tension roller support members8, 10, 25, on which one of the tension rollers2bis rotatably supported, for displacing the tension roller2bto apply tension to the metal ring W, and a rolling processing completing assembly27for 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 member18interposed between the rolling cylinder14and its piston rod15. The tension applying assembly has a second resilient member28interposed between a piston rod24of the tension cylinder23and the tension roller support member25.
