ABSTRACT:
Apparatus for the production of multilayer laminated plates, in particular circuit boards for electrotechnical applications, wherein webs of glass fiber roving fabric are impregnated with a synthetic resin binder, and subsequently pressed in a dual belt press. Upstream of the press, a heating table comprising a plurality of heating panels is provided. The webs of material, coated with the binder, are combined and impregnated in the heating zone. In the heating zone the binder used may be maintained exactly at the processing temperature. Rapid hardening binders may be used so that the transition of the binder from its liquid to its solid state takes place in the press even during short press durations.
