Method for the manufacture of contour-stable objects. ABSTRACT By means of a procedure for the manufacture of contour stable objects a fluidized fibre raw material is deposited on a moulding foundation through suction of a pulp of the fibre raw material on that foundation. For this purpose the foundation is applied with an easily drainable pulp created from the fluidized fibre raw material layer in such an amount and the suction is carried out controlled in such a way that on the foundation through suction a fibre raw material layer is deposited having such wall thickness that it substantially provides the desired contour stability of the object.

Why it's free to use
- Filed October 24, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 24, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 24, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
