Abstract: A method and apparatus for preparing relatively large size foundry moulds and cores from cold-setting foundry sand mixtures wherein successive batches of sand and binder on the one hand with sand and catalyst on the other hand are mixed in a chamber having a rotary mixing element. The batches are discharged from the chamber by gravity into a mould or core box and the chamber is purged by a blast of compressed gas between the successive mixing operations.

Abstract: Apparatus for moulding confectionery, comprising a series of moulds, each of which is divided into a fixed half and a hinged half which is normally aligned with the fixed half, a conveyor for traversing the moulds in sequence past a filling station, through a cooling zone to a discharge station and back to the filling station, a depositor at the filling station which is arranged to deposit different materials into moulding cavities in each half of each mould, mechanism disposed at a folding station beyond the cooling zone for folding the hinged half of each mould about its hinge against the fixed half and effecting deposition of the contents of the moulding cavities thereof into the moulding cavities of the fixed half, mechanism disposed at a following unfolding station for returning the folded hinged half of each mould into alignment with its fixed half, and means for inverting the moulds prior to arrival at the discharge station and turning them right way up during their return to the filling station.
