Abstract
A shearing machine for trimming flat material, particularly sheets and strips of metal, includes a rotary blade shear with rotary blade shafts which support the rotary blades and are mounted in an upper blade housing and a lower blade housing. For adjusting the blade gap and the blade overlap in dependence on the material thickness and the material strength, a transverse eccentric is mounted between the upper and lower shear housings so as to connect these housings. The shearing machine further includes a center cut shear with rotary blade shafts which support the rotary blades and are mounted in an upper blade housing and lower blade housing, a frame supporting the center cut shear, and a blade gap adjusting device with a reversible transverse eccentric, wherein the blade gap adjusting device is mounted between the frame and the upper rotary blade of the center cut shear and acts with its transverse eccentric on the end of the movably constructed upper blade housing at the side of the blade.
