Abstract
A process for driving and synchronizing rolls, in particular the rolls of a strip casting facility, is such that each roll is driven by a separate motor drive via gearing, and the turning speed of the motor is regulated. The synchronizing of the motor drives during idling of the rolls takes place via miter gearing coupled to the motors and a sliding coupling between these sets of gears in addition to a shaft connecting them; the synchronizing is undertaken via manual or automatic control of motor turning speed as a function of roll speed and roll diameter.
