ABSTRACT:
For the manufacture of oval dishes, a machine has two work supports arranged to rotate moulds eccentrically for clay on the moulds to be shaped into oval forms. At a first, spreading, station the clay is engaged by a pancake-type spreading roller which squeezes a piece of clay into an oval shape. The mould is transferred to a second, or finishing, station where a finishing roller rolls the clay to the desired configuration of the oval dish. The spreading roller is driven. The finishing roller may be driven or it may rotate freely, a brake being applied to the free roller, for the end of a finishing operation, to improve the surface finish of the ware.
