Abstract
Abstract A floral base is made by hot wire cutting a foam of expanded polystyrene beads, thereby forming a smooth skin over the cells at the cut surface; differentially wire brushing the hot wire cut surface, lightly in some areas so that the wires only slice the surface skin and more deeply in adjacent areas so that the wires gouge out beads to form cavities and roughly parallel channels; then coating the surface with a latex paint. The resultant material surprisingly simulates the appearance of rough weathered lumber.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
The method of simulating the appearance of rough weathered lumber with a foam material, comprising, providing a rigid, closed cell foam of cohered, expanded polystyrene beads, cutting said foam to form a desired shape therefrom, wire brushing the surface of said shape to form spaced, elongated, generally parallel but irregular grooves and cavities on it while varying the brushing action on different areas of said surface such that at some regions thereof the beads at the surface are merely cut by the wires of the brush while at other regions the wires gouge so deeply as to remove beads as irregular chunks and thereby form said cavities and grooves, removing the loose abraded material, and applying a latex paint over the surface so prepared to seal and color the same.
Claim 2
Independent Claim
130 words
The method of simulating the appearance of rough weathered lumber with a foam material, comprising, providing a rigid, closed cell foam of cohered, expanded polystyrene beads, cutting said foam to form a desired shape therefrom, wire brushing the surface of said shape to form spaced, elongated, generally parallel but irregular grooves and cavities on it while varying the brushing action on different areas of said surface such that at some regions thereof the beads at the surface are merely cut by the wires of the brush while at other regions the wires gouge so deeply as to remove beads as irregular chunks and thereby form said cavities and grooves, removing the loose abraded material, and applying a latex paint over the surface so prepared to seal and color the same.
Claim 3
Dependent Claim
28 words
The method of claim 1 wherein said cutting is carried out by the hot wire technique, so that a smooth surface skin is formed over the cut beads.
Claim 4
Dependent Claim
22 words
The method of claim 1 wherein said surface is brushed by a rotating gang of spaced apart wire brushes of irregular shapes.
Claim 5
Dependent Claim
21 words
The method of claim 3 wherein said wire brushes are mashed radially inwardly to deform the brushes prior to said brushing.
Claim 6
Dependent Claim
17 words
The method of claim 1 wherein said latex paint is thinned approximately 1:1 by volume with water.
Claim 7
Dependent Claim
25 words
The method of claim 1 wherein said latex paint is admixed with up to about 8 percent by weight of a water dispersible foam glue.
Claim 8
Dependent Claim
96 words
A foam material which simulates weathered rough lumber, said material being a rigid, closed cell foam of cohered, generally spherical expanded polystyrene beads and having a cut major surface, the cut beads at said major surfaces having a flat skin thereover, a series of generally parallel irregular grooves and cavities of differing width and depths formed in said major surface, said grooves and cavities being defined by removal of groups of entire beads, said major surface also having thereon a plurality of much narrower, elongated shallow slit-like cuts, said surface being coated with a latex paint.
Claim 9
Dependent Claim
96 words
A foam material which simulates weathered rough lumber, said material being a rigid, closed cell foam of cohered, generally spherical expanded polystyrene beads and having a cut major surface, the cut beads at said major surfaces having a flat skin thereover, a series of generally parallel irregular grooves and cavities of differing width and depths formed in said major surface, said grooves and cavities being defined by removal of groups of entire beads, said major surface also having thereon a plurality of much narrower, elongated shallow slit-like cuts, said surface being coated with a latex paint.
Claim 10
Dependent Claim
15 words
The material of claim 7 wherein said major surface is a hot wire cut surface.
Claim 11
Dependent Claim
18 words
The material of claim 7 wherein said foam has a density of about 0.7-2.0 lbs. per cubic foot.
Claim 12
Dependent Claim
18 words
The material of claim 7 wherein the beads in said grooves in part present generally spherical exposed surfaces.
