Abstract

A tile moulding method for gypsum tiles designed to save time and wear on the moulds, employs an auxiliary mould in which the filling material is poured and allowed to harden, then it is removed and inserted in the main mould (1). This mould has a hinged frame (3) which is swung down and secured by fasteners (6) at the end remote from the hinge (4). Incorporated in the base plate (1) are air release valves (10) between hollows in the tile and an air release channel (11) through the base. In an alternative design, the upper frame is not hinged but is held down entirely by quick release damps, and the air escape fittings are cast into the tile itself.
