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.
An in-line vacuum coating system having a vacuum coating chamber including at least one coating unit, and a carrier, adapted for movement through the vacuum coating chamber, for holding tubular substrates that can be rotated about their respective longitudinal axis, comprising a rotatable toothed shaft installed in a fixed position in the chamber and is connectable to a rotary drive, and a gearwheel for engagement with the toothed shaft, the gearwheel being mounted in a rotatable manner on the carrier and to be moved longitudinally under spring loading by a predefined distance counter to direction of travel of the carrier.
