ABSTRACT:
A first turntable (4) has a plurality of posts (6) equidistantly distributed and arranged in a circle on the turntable (4), wherein a plurality of substrates (7) can be stacked on each post (6). Stationary loading (9) and unloading stations (10 11) are provided and the distance between each pair of adjacent stations (9, 10, 11) corresponds to the distance between each pair of adjacent posts (6), the first turntable being rotated stepwise so that each post can be stopped successively at adjacent stations. A second turntable (12) is rotated stepwise through a loading station (15), a transfer station (16) and an unloading station (17). A loading arm transfers substrates from the loading station of the first turntable to the loading station of the second turntable, a transfer arm transfers the substrates from the transfer station to a coating station, and an unloading arm transfers coated substrates from the unloading station of the second turntable to either of the two unloading stations of the first turntable. A control system (33) includes a sensor (29), a counting device (30) and a servo motor (31), the servo motor (31) driving the unloading arm (21), the unloading station which receives a substrate being selected by the control system (33).
