Abstract: An endless conveyor having a plurality of molding tray supports is mounted on an intermittently indexing turntable. A press of the type adapted to form the clay into lumps deposits these lumps into molding trays on the conveyor, and thereafter the trays pass successively through a series of stations where the loaded trays are trimmed, where the loaded trays are tilted, and where the moldings are dropped onto carrying pallets and stations for washing, drying, and sanding of the empty trays and a station for tilting the molding trays back to the filling position. The tray supports are tiltably mounted about radial axes to enable tilting of the trays and a device for supplying the pallets for the empty trays and for the discharge of the pallets loaded with moldings extends diametrically underneath the turntable adjacent the unloading station.
