Abstract
Vacuum apparatus for coating substrates by rotation including a vacuum chamber with an elongated material source having a longitudinal axis and a transverse axis, a substrate rack with a plurality of fastening points for the planar arrangement of a plurality of substrates above the material source in a substantially uniform distribution over its surface and a drive associated with the substrate rack for rotating substrates. The substrate rack has to parallel substrate bearers disposed fork-wise with couplings for the substrates positioned on the confronting inner sides of the substrate bearers. The substrate bearers are connected by angle drives to the substrate couplings and a motor via a drive shaft.
