The paper describes solving of problem of permanent deformation of the sheet end when cut using the flying pendulum shears. The permanent cross deformation is caused by the upper double oblique knife. Result of the solution is that the lower knife will not be straight as up to now, but also double oblique, identical with the upper knife, however, with half inclination. We have come to these results by computer modeling of the existing and new states. Subsequently, we have compared these two states and determined the optimum solution.
