Abstract
A device and a method for separately transporting substances are provided. The device and method according to the invention can especially be used in connection with an unit for producing DVDs. Preferably, the device according to the invention has for each substrate an input station, a processing station and an output station, which stations are arranged on the circular arc at given distances &agr;. Furthermore, grippers are provided, which are arranged on said circular arc at given distances &agr; and can be simultaneously rotated around an axis through the center of said circle through an angle &bgr;. Each gripper transports one substrate to the processing and output stations in a rotational movement. It is the advantage of the invention that the mixing-up of substrates is avoided.
