Abstract
A substantially continuous method for forming a structural panel of indefinite length is disclosed. The method includes the steps of preparing a settable mixture, conveying the mixture in a flowable state to a load chamber, progressively forcing the mixture from the load chamber through an inlet toward an outlet of an open ended mold chamber by a compression device at least partially curing the mixture within the mold chamber, resisting movement of the mixture through the mold chamber until a predetermined consolidation pressure or density within the mold chamber is achieved, subsequently allowing movement of the mixture through the mold chamber in response to further mixture being forced through the inlet by the compression device, and allowing the mixture to cure, thereby progressively forming a structural panel of substantially indefinite length.
