Реферат: 630,301. Moulding fibro-cement pipes &c. CELLACTITE & BRITISH URALITE, Ltd., and KINGSBURY, H. W. June 23 1947, No. 16545. [Class 87 (ii)] Relates to the manufacture of pipes and other articles from fibrous-cement composition in a divided mould, in which sheets of plastic composition are pressed into the mould cavities, the two parts of the mould being afterwards superposed and the two parts of the moulded article united. According to the invention removable linings are provided for the moulding cavity of each mould part, so that a moulded article can be removed with the lining. Another lining may then be inserted in each mould part for the moulding of another article, so that continuous production is ensured. The linings may be made of synthetic resin e.g. polythene or " Perspex" (Registered Trade Mark). The mould shown, for making a pipe elbow, is in two parts 1, 2 hinged together at 3, the mould cavities of each part having linings 4, 5.
