ABSTRACT:
A concrete form molding is formed of a molding body of closed cell extruded polystyrene material. The molding body includes at least one molding face comprising an extruded molding face formed in the polystyrene material extrusion process. The concrete form molding may also include one or more cut molding faces that are formed after the material is extruded. Each cut molding face is also made up of substantially all closed polystyrene cells. The apparatus of the invention includes an arrangement for precisely supporting a sheet of closed cell extruded polystyrene material vertically and horizontally with respect to a series of laterally spaced apart forming elements. The apparatus also includes structure for advancing the sheet through the forming elements so that the forming elements make contact with the polystyrene material and melt the material. The molten polystyrene material closes substantially all of the cells intersected by the forming elements to form the cut molding faces.
