Claim:
A method of reconditioning at least one of a first corrugating roll and a second corrugating roll being intermeshed with each other to manufacture a fluted corrugated medium, the first and the second corrugating rolls each having a fluted outer periphery surface and being mounted in a single facer for manufacturing a single-faced corrugated cardboard sheet made from the fluted corrugated medium and a back liner after being used for manufacturing the single-faced corrugated cardboard sheet, the method comprising: conditioning the at least one corrugating roll such that a curvature of an arcuate surface of a crest on the at least one corrugating roll including a flute tip is increased as compared to the curvature before the conditioning, while minimizing polishing of the flute tip of the crest to maintain a maximum diameter of the at least one corrugating roll.
