Abstract
An apparatus for fabricating molded articles includes a turntable rotatable about an axis and having an edge. A number of independent diaphragm presses are supported for rotation with the turntable and are spaced from its axis of rotation. A fixed high-frequency heating station is positioned above and in the vicinity of the edge of the turntable, the station including a hood which defines a cavity into which the presses are sequentially positioned. A cooling device is positioned either to the side of the turntable or mounted on the turntable coaxially with its axis of rotation. Conduits connect or couple the cooling device to the presses to effect cooling of the presses subsequent to removal from the heating station as they advance to a parting station.
