Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
A method of producing a plastic ornamental layer comprising: (a) Constructing a first frame having members corresponding to dividing lines in the ornamental layer to be produced; (b) securing dividing strips to said members; (c) placing said first frame with dividing strips down on top of a mold plate; (d) applying adhesive to bond said strips to said mold plate; (e) constructing a second frame having an inner face as a mold wall defining the boundaries of the layer being produced; (f) securing said second frame to said mold surface about said first frame; (g) removing said first frame leaving said strips bonded to said mold surface; (h) filling the space within said second frame to a predetermined level covering said strips with a curable plastic mix; (i) curing said plastic mix to form a hardened layer; (j) removing said second frame; and, (k) removing the cured layer from said mold surface with said strips embedded in said layer.
Claim 2
Independent Claim
159 words
A method of producing a plastic ornamental layer comprising: (a) Constructing a first frame having members corresponding to dividing lines in the ornamental layer to be produced; (b) securing dividing strips to said members; (c) placing said first frame with dividing strips down on top of a mold plate; (d) applying adhesive to bond said strips to said mold plate; (e) constructing a second frame having an inner face as a mold wall defining the boundaries of the layer being produced; (f) securing said second frame to said mold surface about said first frame; (g) removing said first frame leaving said strips bonded to said mold surface; (h) filling the space within said second frame to a predetermined level covering said strips with a curable plastic mix; (i) curing said plastic mix to form a hardened layer; (j) removing said second frame; and, (k) removing the cured layer from said mold surface with said strips embedded in said layer.
Claim 3
Dependent Claim
44 words
A method according to claim 1 wherein constructing said first frame comprises constructing a plurality of subframes and interconnecting said subframes to form a unitary frame assembly in which each of said subframes defines a pattern section of the ornamental layer to be produced.
Claim 4
Dependent Claim
23 words
A method according to claim 1 wherein said first frame is constructed with extended portions that index the positioning of said second frame.
Claim 5
Dependent Claim
25 words
A method according to claim 1 wherein said securing dividing strips comprises cutting grooves along said members and inserting said dividing strips into said grooves.
Claim 6
Dependent Claim
34 words
A method according to claim 1 wherein said strips delineate a plurality of divided sections and said filling comprises filling each of said sections with a different plastic mix to produce a decorative pattern.
Claim 7
Dependent Claim
24 words
A method according to claim 5 wherein said different plastic mix is determined by adding filler materials of different characteristics to a plastic resin.
Claim 8
Dependent Claim
45 words
A method according to claim 1 wherein filling the space within said second frame is followed by adding a core panel on top of the uncured plastic and filling a border area around said core panel and inside said second frame with additional plastic mix.
Claim 9
Dependent Claim
27 words
A method according to claim 1 wherein said constructing a second frame comprises applying a material having a glassy surface to the interior of said second frame.
Claim 10
Dependent Claim
28 words
A method according to claim 1 wherein said dividing strips are constructed with a thickness of 1 to 5 mm. and a width of 5 to 10 mm.
