摘要

The device has bearing sides (1, 2) staying at a distance from each other and applying a stab to be worked on an even surface, where one side is formed opposite to the other. Each side has a base area, spacers (3-5) arranged on the base area and a connection for a vacuum pump in an inner side of a surface closed by a rubber seal. Surfaces of the spacers are formed in a corrugated manner, where the spacers consist of plastic or metal.
