<p>Control unit to obtain bidirectional traverse of the cutting members in a machine for the parting and/or cutting of a material in sheet, preferably of paper type, to obtain reciprocal positioning of the knife and counterknife required for cutting. The control unit according to the invention comprises pneumatically drivable means, which, once activated, determine the coupling of the means of support of the knife and counterknife to a worm screw in rotation which causes horizontal bidirectional traverse of said means of support.</p> |
