The article describes a new design of the chevron knife for cross-cutting of thick sheets. On the basis of the results of the finite elements modeling has been performed a comparative analysis of the quality of the sheet for the cases of cross-cutting of chevron knives of classical and the proposed design. As an indicator was taken the maximum deviation from flatness. Also it was received an expression for determining this value, depending on the width of the sheet and the tensile strength of material when the new chevron design knife is using.
