Shearing apparatus comprises a vertically movable shear assembly for releasably clamping the strip material during shearing, and a transversely movable shear assembly which cooperates with the vertically movable shear assembly to shear the strip material during traversal across the strip. A cam roll track may be provided for supporting one end of the mounting shaft for the transversely movable shear assembly during traversal across the strip material to take the load off the shaft, and electromagnets may also be provided to resist bowing of the rectangular shear blade for the vertically movable shear assembly resulting from separation forces created during shearing without having to provide a large superstructure therefor. The support for the transversely movable shear assembly may be mounted for pivotal movement to permit adjustment of the vertical clearance or overlap between both shear blades, and provision may also be made for adjusting the axial or lateral clearance between such shear blades.
