Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 284 words
Apparatus for manually applying a continuous edge band to the edges of a panel of woody material comprising: 1. a smooth, flat and hard work platform of dimensions adequate to yield a working area at the front portion thereof and large enough to accommodate panels of a variety of sizes; 2. means for storing a supply of edge banding material having a heat activatable adhesive on the backside thereof on said work platform near the upper edge thereof; 3. an adjustable guide means mounted on said work platform adjacent the supply of edge banding material for directing edge banding material of different thickness from the storage area to the working area of said work platform; 4. a heated means mounted on said work platform adjacent said guide means and in the vicinity of said working area for contacting said edge banding material to activate the adhesive thereon, said heated means further comprising an elongated heated platen having an initial curved portion with a curvature that is pronounced at its leading edge adjacent the adjustable guide means for assuring an immediate and intimate cooperation between the edge banding material and the heated platen after the edge banding material passes through said guide means, and a straight second portion at the trailing edge thereof; 5. a spring biased pressure roller device mounted on said work platform adjacent to and downstream of the trailing edge of said heated means for applying a uniform and continuous pressure to the panel edge after the application of said edging material thereto; and, 6. a finishing means mounted on said work platform adjacent said pressure roller device for providing a substantial bond between the panel edge and the edge banding material.
Claim 2
Dependent Claim 284 words
Apparatus for manually applying a continuous edge band to the edges of a panel of woody material comprising: 1. a smooth, flat and hard work platform of dimensions adequate to yield a working area at the front portion thereof and large enough to accommodate panels of a variety of sizes; 2. means for storing a supply of edge banding material having a heat activatable adhesive on the backside thereof on said work platform near the upper edge thereof; 3. an adjustable guide means mounted on said work platform adjacent the supply of edge banding material for directing edge banding material of different thickness from the storage area to the working area of said work platform; 4. a heated means mounted on said work platform adjacent said guide means and in the vicinity of said working area for contacting said edge banding material to activate the adhesive thereon, said heated means further comprising an elongated heated platen having an initial curved portion with a curvature that is pronounced at its leading edge adjacent the adjustable guide means for assuring an immediate and intimate cooperation between the edge banding material and the heated platen after the edge banding material passes through said guide means, and a straight second portion at the trailing edge thereof; 5. a spring biased pressure roller device mounted on said work platform adjacent to and downstream of the trailing edge of said heated means for applying a uniform and continuous pressure to the panel edge after the application of said edging material thereto; and, 6. a finishing means mounted on said work platform adjacent said pressure roller device for providing a substantial bond between the panel edge and the edge banding material.
Claim 3
Dependent Claim 27 words
means for storing a supply of edge banding material having a heat activatable adhesive on the backside thereof on said work platform near the upper edge thereof;
Claim 4
Dependent Claim 27 words
means for storing a supply of edge banding material having a heat activatable adhesive on the backside thereof on said work platform near the upper edge thereof;
Claim 5
Dependent Claim 40 words
The apparatus of claim 1 wherein said roller device includes an inner roller with an outer cylindrical sleeve which forms a guide slot in the lower portion thereof for guiding the combined panel and edging material during the banding process.
Claim 6
Dependent Claim 36 words
The apparatus of claim 2 wherein said roller device is mounted so that the outer cylindrical sleeve thereof can be positioned for varying the width of said guide slot to accommodate different thicknesses of edging material.
Claim 7
Dependent Claim 36 words
an adjustable guide means mounted on said work platform adjacent the supply of edge banding material for directing edge banding material of different thickness from the storage area to the working area of said work platform;
Claim 8
Dependent Claim 36 words
an adjustable guide means mounted on said work platform adjacent the supply of edge banding material for directing edge banding material of different thickness from the storage area to the working area of said work platform;
Claim 9
Dependent Claim 96 words
a heated means mounted on said work platform adjacent said guide means and in the vicinity of said working area for contacting said edge banding material to activate the adhesive thereon, said heated means further comprising an elongated heated platen having an initial curved portion with a curvature that is pronounced at its leading edge adjacent the adjustable guide means for assuring an immediate and intimate cooperation between the edge banding material and the heated platen after the edge banding material passes through said guide means, and a straight second portion at the trailing edge thereof;
Claim 10
Dependent Claim 96 words
a heated means mounted on said work platform adjacent said guide means and in the vicinity of said working area for contacting said edge banding material to activate the adhesive thereon, said heated means further comprising an elongated heated platen having an initial curved portion with a curvature that is pronounced at its leading edge adjacent the adjustable guide means for assuring an immediate and intimate cooperation between the edge banding material and the heated platen after the edge banding material passes through said guide means, and a straight second portion at the trailing edge thereof;
Claim 11
Dependent Claim 50 words
The apparatus of claim 3 wherein the face surface of the guide slot of said roller device extends forward of the plane defined by the second portion of said heated platen in the inoperative condition, but then moves back against its resilient mounting when the panel comes in contact therewith.
Claim 12
Dependent Claim 37 words
The apparatus of claim 4 wherein the resilient mounting for said roller device includes spring devices interposed between a front bracket mounted contiguously with said roller and a rear bracket fixedly attached at a spaced location therefrom.
Claim 13
Dependent Claim 43 words
a spring biased pressure roller device mounted on said work platform adjacent to and downstream of the trailing edge of said heated means for applying a uniform and continuous pressure to the panel edge after the application of said edging material thereto; and,
Claim 14
Dependent Claim 43 words
a spring biased pressure roller device mounted on said work platform adjacent to and downstream of the trailing edge of said heated means for applying a uniform and continuous pressure to the panel edge after the application of said edging material thereto; and,
Claim 15
Dependent Claim 27 words
a finishing means mounted on said work platform adjacent said pressure roller device for providing a substantial bond between the panel edge and the edge banding material.
Claim 16
Dependent Claim 27 words
a finishing means mounted on said work platform adjacent said pressure roller device for providing a substantial bond between the panel edge and the edge banding material.
Claim 17
Dependent Claim 39 words
The apparatus of claim 5 wherein the finishing means comprises a second roller having straight sides and being fixedly mounted so that the face surface thereof coincides with the plane defined by the second portion of said heated platen.
