Abstract

The process is particularly for the casting of concrete cesspits, the material being poured into a mould containing cores so as to produce holes in the finished article. Pouring and compression takes place in a mould (5) open at one side, from which the casting is removed by inversion of the mould. The cores (10) are so mounted that it is unnecessary before doing this to move them or any part of them. Where holes have to be produced at right angles to the knock-out direction, the core can be of the hollow expendable type.
