Abstract
A plunger (14) is displaceably mounted in a vacuum chamber (42) and movable on a first linear path into the plane of substrate (20), for the mounting and for the transport of the mask (15) provided with a bore (32) receiving the plunger (14). A slide (41) having a forked extremity is movable from an airlock chamber (39) transverse to the first linear path to engage an annular flange of the mask (15). In a return movement the mask is transported into the removal airlock chamber (39) from which the mask is then removable by means of a removal plunger (48).
