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 rollersfor supporting a metal ring W, a rolling rollerfor rolling the metal ring W, a rolling assembly for pressing the rolling rolleragainst the metal ring W, a tension applying assembly having a tension cylinderengaging tension roller support members, on which one of the tension rollersis rotatably supported, for displacing the tension rollerto apply tension to the metal ring W, and a rolling processing completing assemblyfor 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 memberinterposed between the rolling cylinderand its piston rod. The tension applying assembly has a second resilient memberinterposed between a piston rodof the tension cylinderand the tension roller support member

A drum slicing apparatus is capable of highly accurately and efficiently slicing a drum made of a thin metal sheet which is relatively highly flexible. The drum slicing apparatus has a support shaft rotatable about its own axis, a cylindrical drum holder supported on the support shaft for holding the drum by pressing engagement with an inner circumferential surface of the drum over an entire length thereof, and a slicing device having slicing edges for slicing the drum into the metal rings by engaging and cutting into the drum at predetermined cutting positions thereon while the drum is being rotated by the support shaft through the drum holder.
