Belt grinder for creating surface structures

A belt grinder for grinding and structuring a flat workpiece, in which the workpiece passes through the belt grinder in a predetermined direction of passage (P1),

• with at least one structuring device;
• with at least one transport unit for the transport of the workpiece in the direction of passage (P1) past a machining area of the structuring device,
• the structuring device comprising:
• at least one endless grinding belt guided over deflection elements in at least one direction of circulation (P3), the width of which substantially extending over the working width of the belt grinder and being guided over deflection elements, the longitudinal axes of which are directed transversely to the direction of passage (P1) of the workpiece,
• an endless press-on belt configured and arranged such that is exerts a force from the inside on the grinding belt in a press-on area, the endless press-on belt being drivable with the aid of a drive unit,
• the direction of circulation (P2) of the press-on belt runs transversely to the direction of circulation (P3) of the grinding belt at least in the press-on area,
• wherein the structuring device and the transport unit are configured and arranged such that the workpiece guided past the structuring device is contacted by the machining area of the grinding belt, characterized in that
• the structuring device comprises a control unit which controls the drive unit of the press-on belt such that the drive unit drives the endless press-on belt optionally in a first direction of circulation (P2) or in a second direction of circulation opposite to the first direction of circulation (P2).
