A set of two reversing finishing stands is arranged in direct succession between the forward reversing coiler and a rear reversing coiler, the distance between the roughing stand and the finishing stands being just sufficient to accommodate the forward reversing coiler. The set of finishing stands and the roughing stand are selectively operable individually and jointly with each other.Field of SearchTo reverse-roll the workpieceChanging orientation or direction of work Plural roller-couples (e.g., successively or optionally usable) With material-handling between successive couples Including successively-acting roller-couples By means (other than a tool) modifying temperature of work With modification or control of temperature of work, tool or machine | |
