Device for coating extra-long sheet-type substrates, in particular glass panes, in a vacuum coating system

A device for coating planar substrate plates, in a vacuum coating system, said device having the following features:

• a) a sequence of chambers disposed on an entry side that are to be passed by the substrate plates (9), said sequence of chambers comprising an entry lock chamber (1), an entry buffer chamber (2), and an entry transfer chamber (3), wherein each of the sequence of chambers at the entry side is closable in an air-tight manner by means of a flap valve (8, 11, 15), and wherein the transfer chamber (3) is followed by a region of process chambers (4), and the process chambers (4) are followed by an exit-side sequence of an exit transfer chamber (5), an exit buffer chamber (7) and an exit lock chamber (8);
• b) a transport device (10) comprising rollers;
• c) a vacuum pump (13) having an adapter flange (14) in the region of the entry buffer chamber (2);
• d) at least one flow baffle (12) in the region of the buffer chamber (2);
• e) a first adjustment mechanism (16) for the longitudinal displacement of the at least one flow baffle (12), and a second adjustment mechanism (17) for the height adjustment of the at least one flow baffle (12);
• and
• f) a control assembly for controlling the coating device.
