ABSTRACT:
A method of producing cement mortar mouldings is provided. Cement mortar material is supplied onto a lower mould. The lower mould is then brought into a vertical alignment with an upper mould. The lower and upper moulds are pressed to each other to compress the cement mortar material which is, in turn, dehydrated by suction means. While maintaining the suction, the lower mould is separated from the upper mould to leave a moulding on the upper mould. This mould is placed on a conveyor for later processing.
An apparatus for producing cement mortar mouldings is also provided. The apparatus comprises upper and lower moulds, suction means, mould actuating means, and conveyor means. The suction means is provided in association with the upper mould to assure both dehydration and holding of the molding manufactured from the compressed from the moulding material.
