METHOD OF MOULDING A FLOWABLE SETTABLE MATERIAL

A method of compression moulding of a flowable settable material (14), particularly particulate cork admixed with adhesive. The material is positioned in a mould space defined between opposed platens (16) of a press (20), the platens being moved towards each other to effect the compression. During c...

Zusammenfassung:	A method of compression moulding of a flowable settable material (14), particularly particulate cork admixed with adhesive. The material is positioned in a mould space defined between opposed platens (16) of a press (20), the platens being moved towards each other to effect the compression. During compression, the material (14) is constrained against sideward outflow, relative to the compression direction, by a collapsible wall (12), positioned between the platens so as to be collapsed as the platens are moved to effect compression. The wall (12) may be formed of paper honeycomb material. Procédé de moulage par compression d'un matériau fluide durcissable (14), en particulier du liège particulaire mélangé à un adhésif. Le matériau est placé dans un espace de moulage défini par les plateaux opposés (16) d'une presse (20) et les plateaux se rapprochent pour effectuer la compression. Pendant la compression, une paroi repliable (12) placée entre les plateaux de façon à se replier à mesure que les plateaux se rapprochent pour comprimer le matériau (14) empêche celui-ci de déborder latéralement par rapport à la direction de compression. La paroi (12) peut être formée d'un papier en nid d'abeilles.
