ABSTRACT:
A method of constructing a model tree structure and the article resulting therefrom constitute the present invention. First a full three-dimensional pattern is constructed from wire and tin-lead. The pattern is then partially flattened and placed in a rubber mold. The mold is filled in around the pattern with rubber and the entire mold with the pattern in place is heated to vulcanize the rubber and form a mold cavity conforming to the configuration of the pattern. A casting metal is provided which preferably is at least 98% lead. Up to 2% antimony may be added to increase flow characteristics. It is also permissible to include a quantity of tin. The part is cast in the mold using centrifugal casting techniques. After the part has solidified and been removed from the mold it is bent into full three-dimensional form corresponding generally to the initial shape of the pattern. An artificial vegetation covering is provided utilizing a non-ferrous, light-penetrable fibrous material to which is adhered a granular, non-ferrous leaf-simulating material. The substrate is first spray painted and then a layer of adhesive is applied. The granular leaf-simulating material is prepared by grinding rubber-like foam with a suitable liquid colorant until a relatively fine granular product results. The granular material is dried and then sprinkled over the adhesive on the substrate. The partially covered substrate is sprayed with lacquer to eliminate any tackiness attributable to the adhesive and to protect the final product. The completed artificial vegetation product is then stretched over the previously cast tree structure.
