Abstract
A roll stand with a frame, a holder arm arranged in the frame, a shaft for the holder, a holder, a motor, and a transmission agent. The transmission agent includes a first and second toothed wheel mounted on an incoming shaft, which is arranged to be driven by the motor, a third toothed wheel and a fifth toothed wheel are arranged on the shaft for the holder, freewheel hubs are arranged at the shaft for the holder between the third and the fifth toothed wheel. The freewheel hubs are capable of locking a toothed wheel in one direction of rotation. Due to the arrangement of the toothed wheels, a first and second drive path is formed so that the transmission agent is capable of achieving two gear changes on an outgoing shaft, depending on the direction of rotation of the motor.
