Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
Apparatus for cutting recesses in plates, bars, webs, or the like made of foam or similar materials, comprising frame means, a die in whose upper surface a plurality of recesses are formed corresponding to the desired recesses to be formed in the foam plates, means for supporting and continuously moving said foam plates into a cutting area, roller means fixedly mounted on said frame means for rolling support of said means for supporting said foam plates, means for vertically adjustably supporting said plate supporting means for vertical adjustment of said die and thus said foam plates carried thereby, cutting means positioned in said cutting area, a pressure roller above said cutting area, and means for supporting and rotating said pressure roller in a fixed vertical position, said pressure roller compressing said foam plates into the recesses in said die for the desired cutting of said plates by said cutting means.
Claim 2
Dependent Claim
150 words
Apparatus for cutting recesses in plates, bars, webs, or the like made of foam or similar materials, comprising frame means, a die in whose upper surface a plurality of recesses are formed corresponding to the desired recesses to be formed in the foam plates, means for supporting and continuously moving said foam plates into a cutting area, roller means fixedly mounted on said frame means for rolling support of said means for supporting said foam plates, means for vertically adjustably supporting said plate supporting means for vertical adjustment of said die and thus said foam plates carried thereby, cutting means positioned in said cutting area, a pressure roller above said cutting area, and means for supporting and rotating said pressure roller in a fixed vertical position, said pressure roller compressing said foam plates into the recesses in said die for the desired cutting of said plates by said cutting means.
Claim 3
Dependent Claim
48 words
The apparatus of claim 1 wherein said cutting means comprises a cutter disposed behind said pressure roller in the path of travel of said foam plates, said cutter extending over the entire operating width of the apparatus for cutting off the upper layer of the compressed foam material.
