An edger mill comprising a pair of oppositely mounted vertical rolls adapted for relative movement whereby the gap between them can be adjusted. Each roll is provided with a drive including a drive shaft comprising two drive sections extending generally parallel to the direction of roll gap adjustment. The first drive section has a splined portion coupled to a drive pinion for accommodating large adjustments effected in the roll gap when the mill is not under load. The second drive section is connected to the first drive section by a splined coupling which accommodates small roll gap adjustments effected when the mill is under load. |
