ABSTRACT:
A central dryer for electron beam curing is described which includes a first application unit for the application of a first coating to a web. The central dryer for electron beam curing also includes an irradiation unit in which a first electron beam generator and a second electron beam generator are arranged for the irradiation of the web. The electron beam generators arranged in the irradiation unit have connections for at least one pump system to generate an operating vacuum. In addition to this the central dryer for electron beam curing also has a web guiding system which feeds the web successively but not necessarily in direct succession, to the first application unit, the first electron beam generator, the second electron beam generator.
