ABSTRACT:
An apparatus for positioning a roll of a roll stand has respective adjustment spindles operatively engageable with the ends of the roll and rotatable about respective axes in one direction to advance the respective roll end and in an opposite direction to retract the respective roll end. A main transmission has respective rotary outputs connected to the spindles, main inputs, and secondary inputs and a relatively strong main drive has respective rotary output shafts connected to the main inputs of the main transmissions for rotating the spindles therethrough. Respective secondary transmissions have outputs connected to the secondary input of the main transmissions and inputs. Individually operable respective relatively weak secondary drives are connected to the inputs of the secondary transmissions for rotating same and rotating the spindles through the secondary and main transmissions. Respective brakes are engageable with the outputs of the main transmission for arresting same while the secondary drives are operating.
