摘要:
The invention relates to a vacuum coating installation with a transport system for planar substrates which are transported through a vacuum chamber. This transport system comprises several cylinders disposed in parallel. As the driving means for these cylinders one or several motors may be provided, which are located within or outside of the vacuum chamber. The coupling between the motor or the motors and the cylinders in any event takes place via magnet couplings. Since hereby no mechanical coupling established between the driving means and the cylinders, these can readily be separated from one another, which permits providing the cylinders, and with them the sputter cathodes, in a slide-in element which can be moved into and out of the vacuum chamber. If not every cylinder is provided with its own driving means, the cylinders, which are coupled with a driving means, can be connected via V-belts or the like with the other cylinders.

A holding device 12 for mounting at least one screen 9 in a coating chamber 2 of an installation for coating a substrate, especially a glass substrate, is configured such that a screen 9 held by the holding device 12 can be moved at least from a first position within the coating chamber 2 to a second position by movement of the holding device 12. The holding device 12 has means 13 of such kind as to enable the screen 9 to avoid obstructions on the way from the first position to the second position. In particular, during its movement from the first to the second position, the screen 9 is mounted slewably on the holding device 12.

In order that an installation for coating panes of glass can be operated more reliably, the invention proposes a modification of the light barriers used in the installation. On the receiver side of these light barriers there is a row of individual cells which are more or less shaded according to the thickness of the glass pane passing through the ray path of the light barrier. Some cells always deliver a significantly reduced signal which can be evaluated as a reliable indication of the presence of an object in the ray path.
