Abstract

A twin roll caster and a method for operating a machine of this type. The machine includes two casting rolls, that delimit a casting gap between them on its longitudinal sides; two side plates that delimit the casting gap on its narrow sides; and at least one oscillation device, which moves the side plate in an oscillating manner about an axis of oscillation, extending substantially axially parallel to the axes of rotation of the casting rolls. Oscillation device includes two actuators, which are articulatedly coupled to the one side plate and each apply a torque rotating about the axis of oscillation on the one side plate, and a control device that emits control signals, upon which the actuators, individually or together with each other, carry out adjustment movements aligned against one another or parallel to one another.
