Abstract (en)
[origin: EP0459270A2] In order both to improve the quality of curable fibrous concrete products and to provide an apparatus which is better than the prior art, is less susceptible and requires less cleaning and servicing effort, the invention provides that, after carrying out the moulding operation, the correspondingly deformable, still not fully cured plates on a mould table are backed with formwork laid on them from above and then turned together with the formwork through 180 DEG . A sheet provided on the still curable plate, on the underside during transporting, then comes to lie on the top. The production process can be performed by means of a mould table designed as a turning table. <IMAGE>
