Vacuum clamp unit

摘要

The working table(3) has two vacuum channel systems(4,5) separated from each other and charged with a vacuum independently of each other. Each of the two vacuum channel systems has a group of outlet holes(7,8) emerging from the surface of the working table and distributed upon it. The table surface forms a supporting surface for a group of support elements(9) which on their underside each have a vacuum channel opening(10) corresponds to on of the outlet holes of the first group distributed over the table surface.
