ABSTRACT:
The mutually associated moulding tools, such as a suction mould and an associated pressing-and-depositing mould, neither of which are shown, comprise a baseplate (1) with a modularly divided, rectangular area (2) provided with perforations (3), on which area (2) it is possible to secure, e.g. by means of screws, a number of closely adjacent modular mould parts (A,B) with a rectangular outline, each of the modular mould parts (A,B) serving to produce an article (C,D,E) to be separated from the pulp-material shell having been produced in a subsequent operation. With this arrangement, it is possible to keep the cost of manufacturing the moulding tools and the time required for re-arranging them at such low levels, that even small series of articles (C,D,E) may be manufactured profitably.
