Abstract:
1. A method for transporting a sheet-like substrate sheet through a coating installation using a transporting device for transporting sheet-like substrates through a coating installation comprising transporting rollers which are rotatably mounted and horizontally arranged transversely in relation to a transporting direction, wherein uppermost surface lines of the transporting rollers define a transporting plane, wherein end parts of the transporting rollers have a smaller diameter than a middle part of the transporting rollers and baffles which are mounted displaceably in an axial direction of the transporting rollers between a first position and a second position are arranged between the end parts of the transporting rollers and the transporting plane comprising: introducing a material and a carrier gas into a first chamber including the transporting device; heating the material such that a portion of the material vaporizes into a vapor; directing a mixture of the vapor and carrier gas through a second chamber to form a substantially uniform vapor/carrier gas composition; and directing the substantially uniform vapor/carrier gas composition by a vapor distributor toward a surface of a substrate having a temperature lower than the vapor; wherein the baffle is arranged proximate to the vapor distributor to capture stray flux.
