A roller-equipped annealing lehr for flat glass, having a roller conveyor inside a lehr housing, with heating units arranged in pairs above and below the roller conveyor, in rows situated one after another and extending transversely to the feed direction. In a first aspect of the invention, collecting vessels are arranged around a developing cup surrounding a wafer supported by a wafer holder. The service data is compiled based on a service repair history for each vehicle. The converging portion is comparable in chordal length with the throat. The present invention also relates to the use, for the production of pigmented and pigment-free coating materials, or else for adhesives and sealants, of the novel formulations that are curable thermally and curable by actinic radiation.
