ABSTRACT:
A device for control of the slice opening of a slice on a headbox contains several jackscrews that are distributed along and act against the control lip of the slice. A first carriage is moveable along a first track that is parallel to the row of jackscrews. A second carriage runs on a track on the first carriage in direction across the first track. The second carriage contains a drive motor that has a gripping device. By means of control devices and driving devices, the carriages are controlled so that the gripper in sequential order can mate with the drive shaft ends of the jackscrews for adjustment of the profile of the control lip and distance from the fixed slice lip by means of the drive motor.
