Readjustment device and readjustment method for a plate-like workpiece in a processing machine

A readjustment device for a machine tool for processing plate-shaped workpieces, the readjustment device comprising:

• an upper pressure-exerting device having pressure plungers being oriented at a spacing to one another;
• a lower supporting device having at least counter-bearings which are disposed at a spacing to one another and which, in a working position, are oriented so as to fix a plate-shaped workpiece in a clamping manner with respect to said pressure plungers of said upper pressure-exerting device;
• and
• at least one drive device, by means of said at least one drive device said pressure plungers of said upper pressure-exerting device are transferred from a rest position to the working position, wherein at least two of said pressure plungers of said upper pressure-exerting device are coupled to one another and are controlled so as to be movable or pivotable together between the rest position and the working position;
• wherein said upper pressure-exerting device has a holding element on which two pivot axles, which are oriented in a parallel manner, for a pivotable configuration of said pressure plungers are provided at a spacing to one another;
• and
• wherein said pivot axles are disposed at a spacing to one another on said holding element of said upper pressure-exerting device, such that said pressure plungers lie in a line in the rest position.
