MOULDING FIBROUS PRODUCTS

摘要

A cored construction product such as a hollow cored partition panel for a building is made from a compressed mixture of liquid settable powder and wooly fibrous material. The powder and fibrous material are mixed and evenly damped, and the resulting mixture is fed into a vertical mould cavity defined between a core former (11) and two opposed pairs of mould side walls (15, 16) which are movable towards and away from the core former (11) relative to static mould corners (19). The side walls (15, 16) are moved to compress the mixture particularly by means of inflatable tubes (24) bearing on the outer surfaces of the side walls. The side walls are held in position until the mixture sets and the product is then removed from the mould.
