Step form mold

Abstract

A step form mold apparatus includes a support having an upper portion, a lower portion, and a middle portion disposed between, and interconnecting, the upper and lower portions, with the upper portion including a first mold mounting surface extending upwardly from the middle portion, and a first molding form being secured to the support such that the inner surface of the first molding form is disposed in face-to-face relationship with the first mold mounting surface, the outer surface of the first molding form being uneven so as to impart a textured appearance upon materials molded thereagainst.

What is claimed is:  
     
         1 . A step form mold apparatus, comprising: 
 a support having an upper portion, a lower portion, and a middle portion disposed between, and interconnecting, said upper and said lower portions, said upper portion being substantially perpendicularly offset from said lower portion, said upper portion including a first mold mounting surface extending upwardly at least about three inches from said middle portion; and    a first molding form having an inner surface and a generally opposed outer surface, said first molding form being secured to said support such that said inner surface of said first molding form and said first mold mounting surface are disposed in face-to-face relationship with one another, said outer surface of said first molding form being uneven so as to impart a textured appearance upon materials molded against said outer surface of said first molding form.    
     
     
         2 . A step form mold apparatus as in  claim 1 , including a second molding form secured to a second mold mounting surface on said lower portion of said support, said second mold mounting surface being substantially parallel to, spaced from, and facing substantially the same direction as said first mold mounting surface.  
     
     
         3 . A step form mold apparatus as in  claim 2  wherein said second molding form includes an uneven textured outer surface.  
     
     
         4 . A step form mold apparatus as in  claim 1  wherein said first molding form is concave in a longitudinal direction, such that materials molded against said first molding form have an elongated convex profile along a length thereof.  
     
     
         5 . A step form mold apparatus as in  claim 2  wherein said first and second molding forms are fabricated from a polymeric material.  
     
     
         6 . A step form mold apparatus as in  claim 2  wherein said first and second molding forms are fabricated from a vulcanized rubber material.  
     
     
         7 . A step form mold apparatus as in  claim 1  wherein said support is an integral structure.  
     
     
         8 . A step form mold apparatus as in  claim 1  wherein said upper portion is offset from said lower portion by between about one-fourth inch and six inches.  
     
     
         9 . A step form mold apparatus as in  claim 2  wherein said second mold mounting surface is from about three inches and about ten inches in height.  
     
     
         10 . A step form mold apparatus as in  claim 1  wherein said support is up to about twelve feet in length.
