Abstract (en)
[origin: WO2022034026A1] A workpiece (10) passes through a belt grinder (100) for grinding and structuring a flat workpiece (10) in a predefined direction of passage (P1) past at least one machining region of a structuring device (200). The structuring device (200) comprises at least one endless grinding belt (210) which is guided via deflecting elements (212, 214, 216) in at least one direction of revolution (P3) and the width of which extends substantially across the working width of the belt grinder (100, 120), and is guided via deflecting elements (212, 214, 216), the longitudinal axes of which are oriented transversely to the direction of passage (P1) of the workpiece (10). Furthermore, the structuring device (200) comprises an endless pressing belt (220) which is configured and arranged such that it exerts a force from the inside on the grinding belt (210) in a pressing region (229), wherein the endless pressing belt (220) is able to be driven with the aid of a drive unit. The direction of revolution (P2) of the pressing belt (220) runs, at least in the pressing region (229), transversely to the direction of revolution (P3) of the grinding belt (210). The structuring device (200) and the transport unit (110) are configured and arranged such that the workpiece (10) guided past the structuring device (200) comes into contact with the machining region of the grinding belt (210). The structuring device (200) comprises a control unit (510) which controls the drive unit of the pressing belt (220) such that the drive unit selectively drives the endless pressing belt (220) in a first direction of revolution (P2) or in a second direction of revolution that is opposite to the first direction of revolution (P2).
