Abstract: Apparatus and method for molding generally cubical building modules of concrete, the apparatus comprising both internal and external movable mounted molding components and preferably including mechanisms for advancing the components into molding positions and for withdrawing the components from the molding position upon completion of the molding of a module. The method involves the use of such molding components and contemplates certain sequences in the advancement and withdrawal of the molding components for different portions of the modules.

The method involves the use of such molding components and contemplates certain sequences in the advancement and withdrawal of the molding components for different portions of the modules. The outside mold parts comprise superimposed horizontal strips and alternative screw jack and reciprocating rod devices are provided for mounting and sequentially advancing and withdrawing the outside mold strips. Provision is further made for subjecting the concrete cast in the side walls to vibration.
