Abstract (en)

[origin: EP0418413A2] In the case of a process for making vaulted panel-shaped elements from gypsum reinforced with fibres for linings in the wall and ceiling area of residential and commercial buildings, with a view to cost-effective production of individually designed panel-shaped elements it is envisaged that the developable surface of the element to be made is represented in a plane, that the planar representation of the developable surface is projected onto the undeformed flat fibre-reinforced gypsum material, that the fibre-reinforced gypsum material is trimmed according to the projected surface and that then the moisture content of the fibre-reinforced gypsum material is increased and subsequently the moulding of the fibre-reinforced gypsum material to form the vaulted element takes place in a moulding press. <IMAGE>
