Abstract
Abstract In a shearing line comprising slitting shears (3) for thick sheets two gauges (23) for measuring sheet lengths to be cut are provided in the area of the crosscut shears (5). The gauges are disposed across the width of the sheet and are adapted to operate independent of each other so as to cut a pair of longitudinally divided strips of the sheet simultaneously into equal or different lengths.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
A shearing line for metal sheets comprising, in combination, shear means for slitting an advancing metal sheet longitudinally into a pair of split strips, means for feeding a metal sheet to be split to said slitting shear means, crosscut shear means for transverse cutting of said split strips simultaneously, track means for advancing each of said split strips independently of each other in laterally spaced relationship, length sensing means operatively associated with each of said split strips for independently controlling the advance of each of said split strips by said track means, each of said length sensing means being adjustable to advance a predetermined length of each of said strips through said crosscut shear means for said simultaneous cutting of said strips into selected lengths.
Claim 2
Dependent Claim
125 words
A shearing line for metal sheets comprising, in combination, shear means for slitting an advancing metal sheet longitudinally into a pair of split strips, means for feeding a metal sheet to be split to said slitting shear means, crosscut shear means for transverse cutting of said split strips simultaneously, track means for advancing each of said split strips independently of each other in laterally spaced relationship, length sensing means operatively associated with each of said split strips for independently controlling the advance of each of said split strips by said track means, each of said length sensing means being adjustable to advance a predetermined length of each of said strips through said crosscut shear means for said simultaneous cutting of said strips into selected lengths.
Claim 3
Dependent Claim
50 words
A shearing line in accordance with claim 1 wherein said track means includes a pair of laterally spaced substantially parallel tracks having rollers, means for driving the rollers in each of said tracks independently of each other, the adjacent side edges of said tracks defining therebetween a longitudinally extending interval.
Claim 4
Dependent Claim
40 words
A shearing line in accordance with claim 2 wherein the rollers of one of said tracks are of greater length than the rollers of the other of said tracks to thereby provide independently operable roller track paths of differing widths.
Claim 5
Dependent Claim
38 words
A shearing line in accordance with claim 3 wherein said splitting shear means are laterally adjustable to provide a cutting line for said metal sheet extending from the center line of said track means towards said other track.
Claim 6
Dependent Claim
66 words
A shearing line in accordance with claim 4 including idle rollers positioned within said interval between said tracks for supporting the edge portions of said advancing strips, longitudinally extending straight edges associated with each of said tracks for guiding the advance of said split strips and at least one deflection device for moving said split strips laterally apart onto said tracks against the associated straight edges.
