Abstract
An edger mill having a pair of edging rolls mounted for variable positioning apart from each other is powered by a plurality of electric motors driving the rolls from above, having a long shaft extending upwardly from each roll, with a bull wheel connected to each shaft in driving relation, each bull wheel having two or more electric motors connected thereto in driving relation by respective pinions. Synchronization between the edging rolls may be effected by mounting the bull gears in mutual intermeshing relation, or by using synchronous motors so that the common bus supply to the motors constitutes a synchronizing agency to maintain the edging rolls in synchronized relation.
