Abstract: Improved cutting unit for cutting material in bands into strips comprising a rotating blade and counter-blade, carried on their respective supports and translatable along at least one beam of the framework, in which a single pressurized fluid pipe enables the blade-carrying support to be locked on the beam and simultaneously, the two supports released; or alternatively, the blade-bearing support to be unlocked and simultaneously the counter-blade support connected to the blade-carrying one. The lockings and connections are obtained by means of pneumatic pistons placed laterally and in the lower part of the blade-carrying support. The counter-blade consists of two elements fixed together and separated by a centerpiece.

Abstract: The device for positioning the blade cutting edge and intermittently lowering the blade cutting edge includes: a fixed structure comprising two chambers and a central moving rod; two pistons with stems, the pistons moving within the chambers. One of the pistons is opposed by a spring. The blade carrier is hinged at the end of the moving rod and is fixed to the piston stem opposed by the spring and slides along the stem of the other piston. Pressurized fluid is introduced into the chambers by a line provided with a first valve. A second valve intermittently varies the pressure applied to the piston opposed by the spring.
