Method and apparatus for the vulcanisation of a multilayer article

The invention relates to a method and apparatus for vulcanizing a single layer or multilayer article, which includes at least one layer based on at least one rubber. According to the method, the plastic flow phase of the rubber of the single- or multilayer article is done in a first process step, under pressure and in a second method step, the cross-linking phase of the rubber of the single- or multi-layer article without pressure, wherein during the pressureless cross-linking phase used at least two two-dimensional radiation sources are each irradiate the top and bottom of the multilayer article. The inventive method may in this case comprise further process steps.
