Abstract

A grinding machine and method for flat, board-shaped workpieces, especially for particle-board materials, fiber materials, veneer materials, and mineral materials, utilizing at least one continuous belt unit having a grinding belt that is supported upon rollers, a counterpressure element, and means for adjustable spacing the counterpressure element relative to the grinding belt for forming a gap corresponding to the thickness of the workpieces being ground therebetween is improved through the further utilization of support means for maintaining the counterpressure element in a substantially plane-parallel orientation relevant to the grinding belt during grinding. In accordance with a preferred embodiment of the grinding machine, the counterpressure element is a backing roller to which a variable pressure is applied by a pneumatic piston-cylinder unit. In accordance with the method aspect of the invention, the grinding is performed prior to full setting of the bonding agent, whereby the maintaining of the substantially plane-parallel orientation of the grinding belt and counterpressure element is of particular significance.
