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. | InventorsAssigneeApplicationNo. 06/469017 filed on 02/23/1983US Classes:72/202, By means (other than a tool) modifying temperature of work72/229, To reverse-roll the workpiece72/234Including successively-acting roller-couplesField of Search72/229, To reverse-roll the workpiece72/231, Changing orientation or direction of work72/226, Plural roller-couples (e.g., successively or optionally usable)72/227, With material-handling between successive couples72/234, Including successively-acting roller-couples72/202, By means (other than a tool) modifying temperature of work72/200With modification or control of temperature of work, tool or machineExaminersPrimary: Husar, Francis S.Assistant: Katz, Steven B.
