ABSTRACT:
A plurality of webs drawn from respective supply rolls forms a core stack which is passed through a single-level press to press boards from the press stack formed by applying cover foils to the core band. Once the pressed board forming part of the band is advanced from the press, the pressed board can be cut and trimmed from the band. The apparatus has a separating web insertion station for selectively inserting a separating web between core forming layers as part of the band so that, when one or more separating layers are inserted, each press cycle simultaneously forms two boards, but when no separating layer is inserted, only a single board is formed at each press cycle and separating operation.
