ABSTRACT:
A mold with two relatively movable portions, one of them having one or more shallow cavities for the production of substantially flat articles, is provided with lateral guide elements which, upon separation of the two mold portions by a distance exceeding but slightly the depth of these cavities, define with the separated mold portions a vertical channel through which the ejected articles descend with a predetermined orientation onto an underlying conveyor or other receiver therefore. The guide elements may be retractable into the mold portion on which they are supported, or partly receivable in the opposite mold portion when the mold is closed. Some of the guide elements could be extensions of ejectors serving to dislodge a molded article from its cavity.
