Processing machine, workpiece table and method for processing a workpiece

A method comprising:

• providing a long folding machine for machining a workpiece made of sheet metal, wherein the long folding machine comprises (i) a workpiece table defining a supporting area on which the workpiece can be placed at least in sections during machining, and (ii) at least one tool for machining the workpiece while the workpiece is placed on the supporting area, wherein the workpiece table comprises at least one table assembly having a base plate and a swivel plate, the base plate and the swivel plate each defining a portion of the supporting area, wherein the swivel plate is pivotably mounted relative to the base plate in such a way that a swivel movement of the swivel plate can be generated for turning the workpiece over, and wherein the tool is configured to bend a portion of the workpiece to be bent over relative to a clamped portion of the workpiece about a bending axis, and wherein the swivel movement of the swivel plate is defined by at least one swivel axis arranged parallel to the bending axis;
• placing the workpiece onto the supporting area;
• machining the workpiece;
• generating a swivel movement of the swivel plate to turn the workpiece over;
• and
• machining the turned-over workpiece.
