    摘要： A flying shears for trimming plates or sheets has an upper cutter carrier which is connected at its plate exit end to a continuously rotating crank, and at its plate inlet end to a rocker member. The upper cutter has a straight cutting edge which may have an extension directed away from the plate feed plane. The lower cutter may have a straight cutting edge and may be displaceable in and against the plate feed direction by a drive which permits the cutting forces to modify the plate speed. Alternatively the lower cutter may have a curved cutting edge and may be displaceable in a similar manner to the upper cutter. Means are provided for so modifying the displacement speed of the cutters that plates or sheets can be fed through the shears at a uniform speed.
