Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
211 words
A device for automatically and simultaneously making two parallel straight cuts of a predetermined length in a mat, said device comprising: a transporting means; a first pair of cutting means above said transporting means for simultaneously making two parallel straight cuts of predetermined length in a mat at a predetermined angle with respect to the surface of said mat; a first single driving means for urging said first pair of cutting means into and out of said mat; and a first pair of signalling means for activating said first driving means to urge said first pair of cutting means into and out of said mat; wherein said transporting means maintains said mat in a constant position relative thereto and transports said mat in a linear direction; and wherein one of said first pair of signalling means activates said first driving means to urge said first pair of cutting means into said mat while said mat is transported by said transporting means thereby automatically and simultaneously making two parallel straight cuts of a predetermined length in said mat; and wherein the other of said first pair of signalling means activates said first driving means to urge said first pair of cutting means out of said mat after said cuts have been made.
Claim 2
Independent Claim
211 words
A device for automatically and simultaneously making two parallel straight cuts of a predetermined length in a mat, said device comprising: a transporting means; a first pair of cutting means above said transporting means for simultaneously making two parallel straight cuts of predetermined length in a mat at a predetermined angle with respect to the surface of said mat; a first single driving means for urging said first pair of cutting means into and out of said mat; and a first pair of signalling means for activating said first driving means to urge said first pair of cutting means into and out of said mat; wherein said transporting means maintains said mat in a constant position relative thereto and transports said mat in a linear direction; and wherein one of said first pair of signalling means activates said first driving means to urge said first pair of cutting means into said mat while said mat is transported by said transporting means thereby automatically and simultaneously making two parallel straight cuts of a predetermined length in said mat; and wherein the other of said first pair of signalling means activates said first driving means to urge said first pair of cutting means out of said mat after said cuts have been made.
Claim 3
Dependent Claim
52 words
A device according to claim 1 wherein said transporting means comprises a continuous conveyor belt having a first guide bar attached to said belt transverse to the longitudinal axis of said belt and a second guide bar perpendicular to said first guide bar and parallel to the longitudinal axis of said belt.
Claim 4
Dependent Claim
170 words
A device according to claim 2 further comprising a second pair of cutting means above said transporting means for simultaneously making two straight cuts of predetermined length in said mat at a predetermined angle with respect to the surface of said mat; a second single driving means for urging said second pair of cutting means into and out of said mat; and a second pair of signalling means for activating said second driving means to urge said second set of cutting means into and out of said mat; wherein one of said second pair of signalling means activates said second driving means to urge said second pair of cutting means into said mat while said mat is transported by said transporting means thereby making two additional parallel straight cuts of predetermined length in said mat; and wherein the other of said second pair of signalling means activates said second driving means to urge said second pair of cutting means out of said mat after said additional cuts have been made.
Claim 5
Dependent Claim
22 words
A device according to claim 3 wherein said cutting means are oriented such that they provide a bevel cut in said mat.
Claim 6
Dependent Claim
14 words
A device according to claim 4 wherein the angle of said bevel is 45°.
Claim 7
Dependent Claim
29 words
A device according to claim 5 further comprising adjusting means for adjusting the distance between each of the cutting means of said first and second pair of cutting means.
Claim 8
Independent Claim
86 words
A method for making two simultaneous parallel straight cuts of predetermined length in a mat comprising the sequential steps of conveying a mat along a path by a transporting means; triggering a first pair of signalling means to activate and urge a first pair of cutting means into said mat; making, at one time, two parallel straight cuts of a predetermined length in said mat; triggering a second pair of signalling means to activate and urge said first pair of cutting means out of said mat.
Claim 9
Independent Claim
86 words
A method for making two simultaneous parallel straight cuts of predetermined length in a mat comprising the sequential steps of conveying a mat along a path by a transporting means; triggering a first pair of signalling means to activate and urge a first pair of cutting means into said mat; making, at one time, two parallel straight cuts of a predetermined length in said mat; triggering a second pair of signalling means to activate and urge said first pair of cutting means out of said mat.
