【摘要】A continuous molding machine particularly adapted for but not limited, in principle, to the making of waffles includes a lower conveyor carrying a plurality of forms each constituting a first part of a respective two-part split mold, a second conveyor carrying a plurality of forms each constituting the other part of the respective split molds and means for guiding the respective conveyors in respective paths so that the first and second mold parts are carried from spaced apart positions to positions in which the parts meet in registry and each of the molds defined by the parts is thereby closed and then the first and second mold parts are carried away from each other again so that each of the molds is opened. The conveyors carrying the mold parts may be passed through an oven to different extents so that the respective conveyors are heated differently and means are provided for aligning the mating mold parts despite different thermal expansions of the conveyors. Means may be provided for facilitating or positively effecting partial opening of the closed molds to permit the release of gases or vapors contained in the molds. Means may be provided for permitting the closed molds to partially open to release gases or vapors contained therein only upon the reaching of a predetermined minimum gas or vapor pressure in the mold. Means may be provided for swinging the mold parts out of the plane of the conveyor on which they are carried in order to facilitate such operations as cleaning of the mold parts.
