Abstract

An in-line vacuum coating system includes a vacuum chamber, a coating source and a substrate carrier for holding tubular substrates, the carrier being displaceable using the vacuum chamber. A sure method of simply and securely coupling a fixed rotational drive unit to a carrier that can be displaced at a constant rate of speed in an in-line vacuum coating system is accomplished by a fixed splined shaft rotatably installed and connectable to a rotational drive unit, and a gearwheel that can be engaged with the splined shaft and that is rotatably mounted on the carrier. The gearwheel is longitudinally displaceable to a predefined extent in spring-loaded fashion in a direction opposite to the direction of travel of the carrier.
