Abstract
Abstract In the cutting of material to sever a first part thereof from second part thereof along a path in the material, the steps of A. OFFSETTING BY SHEARING SAID FIRST PART FROM SAID SECOND PART ALONG WITH SAID PATH, TO ONLY PARTIALLY CUT SAID FIRST PART FROM SAID SECOND PART, AND TO DISPLACE SAID FIRST PART IN ELEVATION FROM SAID SECOND PART, AND THEREAFTER B. CUTTING SAID FIRST PART FROM SAID SECOND PART TO SEVER THE FIRST AND SECOND PARTS BY SHEARING ALONG SAID PATH TO DISPLACE SAID FIRST PART IN ELEVATION FROM THE SECOND PART IN THE DIRECTION OPPOSITE TO THE DISPLACEMENT OF SAID FIRST AND SECOND PARTS EFFECTED IN STEP (A). The process, and also apparatus for practicing the process are claimed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
Apparatus for cutting material to sever a first part thereof from a second part thereof, comprising: a. a fist pair and a second pair of rotatable, cooperating, shearing disks, the discs of each pair being axially offset with respect to each other; b. said first pair and second pair of shearing disks being disposed in alignment for cutting by shearing the material in succession by, respectively, said first and second pair of shearing disks, along a single path in the material, c. the radially outwardly disposed edge portions of the disks of said first pair of disks being in radially spaced relation for cutting to a depth less than the thickness of the material by displacement of said first part of the material relative to the second part thereof, d. the radially outwardly disposed edge portions of the disks of said second pair of disks being disposed to displace said first and second parts in the opposite direction to a depth sufficient to sever said first and second parts.
Claim 2
Dependent Claim
169 words
Apparatus for cutting material to sever a first part thereof from a second part thereof, comprising: a. a fist pair and a second pair of rotatable, cooperating, shearing disks, the discs of each pair being axially offset with respect to each other; b. said first pair and second pair of shearing disks being disposed in alignment for cutting by shearing the material in succession by, respectively, said first and second pair of shearing disks, along a single path in the material, c. the radially outwardly disposed edge portions of the disks of said first pair of disks being in radially spaced relation for cutting to a depth less than the thickness of the material by displacement of said first part of the material relative to the second part thereof, d. the radially outwardly disposed edge portions of the disks of said second pair of disks being disposed to displace said first and second parts in the opposite direction to a depth sufficient to sever said first and second parts.
Claim 3
Dependent Claim
22 words
Apparatus according to claim 1, the radially outwardly disposed edge portions of the disks of said second pair of disks substantially overlapping.
Claim 4
Dependent Claim
68 words
Apparatus according to claims 1, and a third and fourth pair of rotatable, cooperating shearing disks, and said third and fourth pair of disks being disposed relative to each other as said first and second disks are disposed relative to each other, and being spaced from and parallel to, respectively, the first and second pair of disks, whereby opposite edge portions can be simultaneously cut from said material.
Claim 5
Dependent Claim
13 words
Apparatus according to claims 1 and means for driving each of said disks.
Claim 6
Dependent Claim
20 words
Apparatus according to claims 1, and means for driving the disks of only one of said first and second pairs.
Claim 7
Dependent Claim
102 words
Apparatus according to claim 3, each of said pairs of disks including an upper disk and a lower disk, the upper disks of the first pair and third pair being mounted on a first common shaft, the lower disks of the first pair and third pair being mounted on a second common shaft, the upper disks of the second and fourth pair being mounted on a third common shaft, and the lower disks of the second and fourth pair being mounted on a fourth common shaft, the aligned upper disks and the aligned lower disks overlapping preventing axial movement of the shafts.
Claim 8
Dependent Claim
94 words
Apparatus according to claim 3, each of said pair of disks including an upper disk and a lower disk, the upper disks of the first pair and third pair being mounted on a first common shaft, the lower disks of the first pair and second pair being mounted on a second common shaft, the upper disks of the second and fourth pair being mounted on a third common shaft, and the lower disks of the second and fourth pair being mounted on a fourth common shaft, and means for driving each of said shafts.
Claim 9
Dependent Claim
104 words
Apparatus according to claim 3, each of said pairs of disks including an upper disk and a lower disk, the upper disks of the first pair and third pair being mounted on a first common shaft, the lower disks of the first pair and third pair being mounted on a second common shaft, the upper disks of the second and fourth pair being mounted on a third common shaft, and the lower disks of the second and fourth pair being mounted on a fourth common shaft, and means for driving only the first and second common shafts or the third and fourth common shaft.
Claim 10
Dependent Claim
14 words
Apparatus according to claim 1, the outer surfaces of the shearing discs being cylindrical.
