A cutting unit separating bundles wrapped with a continuous wrap or cutting a flat film in dynamic transit includes a load-bearing structure supporting eccentric wheels hinged on opposite sides of the load-bearing structure and including an outer crown element idly coupled to an eccentric central plate. A heated cutting wire is fixed onto the outer crown element by pins, at a first circumferential portion of the eccentric wheels. A tensioning wire has an elastic compensation element and is fixed to the outer crown element by pins, at a second circumferential portion of the eccentric wheels, so an arc between pins of the first and second circumferential portions is less than 180°. The eccentric central plate is eccentrically fixed to a respective shaft, fixed to a pulley. The pulleys continuously and synchronously rotate to impart alternate motion perpendicular to a continuous wrap or flat film, between engagement and disengagement positions.
