Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
125 words
In a molding apparatus, means for supporting a quantity of moldable fibrous material during a molding operation comprising a rectangular metal frame having tubular end frame members and side rails, each of said end frame members having an outwardly-projecting strip integrally joined therewith providing an end rail, a plurality of spaced linear elements connected with the end frame members, a plurality of spaced linear elements connected with the side rails, said linear elements connected with the end frame members being in crossing relation with the linear elements connected with the side rails, said linear elements providing support means for the fibrous material during a molding operation in which the fibrous material is molded into bodies substantially defined by the areas bounded by the linear elements.
Claim 2
Dependent Claim
