A vacuum coating unit having a pair of side by side transport devices for transporting substrates in a transport direction. Each transport device includes at least one first endless conveyor running in the transport direction and having a conveying element guided around at least two guide rollers or pulleys. The conveying element is located at a distance from a guide device extending in the transport direction parallel to the conveying element in such a way that the ends of the substrates can be introduced into the gap between the conveying element and the guide device of the transport devices and can be moved in the transport direction by the displacement of the conveying elements.

Vacuum coating system comprising a transport unit for transporting substrates

In a transport device, which comprises at least one endless conveyor guided around at least two guide rollers, a monitoring appliance for monitoring motion of a guide roller is positioned on at least one of the guide rollers. The monitoring appliance comprises a first contact element disposed on and electrically connected with the guide roller, and a second contact element disposed near the guide roller. The first and second contact elements are arranged relative to one another in such a way that an electrical contact between them occurs with every revolution of the guide roller, such that the electric potential of the guide roller is transmitted to the second contact element. Additionally, a substrate treatment apparatus comprising such transport device is disclosed.
