Removing deposited material from the edge portions of a plate

摘要

Deposited material is removed from an edge of a plate in the form of a strip, by positioning against the edge of the plate the periphery of a roller that has corrugations along its periphery, the corrugations having sharp edges that extend all the way around the periphery of the roller. The edge of the plate is disposed at an acute angle to the axis of the roller at least at the point of contact of the roller with the edge, and the roller is rotated about its axis in a direction to remove material from the edge of the plate in a direction edgewise away from the plate. The roller is then moved along the plate in a direction parallel to the edge of the plate while maintaining the periphery of the roller in contact with the edge of the plate. Preferably, the axis of the roller is disposed at an acute angle to the plane of the plate.
