<p>In a cross helical rolling mill. wherein work rolls each having an inlet interfacing angle and an outlet interfacing angle are inclinedly disposed at a predetermined lead angle, a pair of drive-roller shoes being drivable and each having an inlet interfacing angle and an outlet interfacing angle are inclinedly disposed at positions adjacent the work rolls in a manner to give a predetermined lead angle. In consequence, the cross helical rolling mill, having a construction rendered compact in size, can stable support a shell under the rolling to effect the smooth rolling.</p> |
