Abstract
On a two-roll rounding machine, in addition to a compressively elastic guide roll and a compressively rigid rounding roll, one or more compressively elastic rolls are provided which have both a rounding function and a supporting function for the rounding roll. These additional rolls may also be supported by a back-up roll. The result is a rounding machine that has very good rounding characteristics even at small rounding diameters.
