Abstract (en)

[origin: EP0406783A2] A process for making hollow articles from lignocellulosic fibres with vegetable binders is presented, by which it is possible to make articles (20) which have a uniform density distribution even in the case of complicated profiling. The dimensions of the articles (20) and their strength can be controlled by the production process presented. A specific setting of the density and of the strength in the article is possible by the process described. The features of the production process are: introducing the suspension into the mould under pressure and compressing the parts (18, 19) of the article. <IMAGE>
