    • The present invention relates to an in-mold cutting unit for a thermoforming machine having at least one mold element (4), at least one counter-mold element (5) intended to cooperate, in use, with a respective mold element (4), and actuation means intended to command the relative movement of the mold (4) and countermold (5) elements;
      the cutting unit comprising:
      at least one annular knife element (60) having a sharp edge (61), and
      at least one counter-cutting element (7) for each knife element (60), defining a sharp counter-edge portion (71), and

      the in-mold cutting unit comprising at least one witness-forming insert (8) removably housable in a respective reception seat (S) at the at least one annular knife element (60) or the at least one counter-cutting element (7), and delimiting at least one recess or incision (89) thereon, during use very close to the sharp edge (61) of the annular knife element (60) or to the sharp counter-edge portion (71) for the formation of a respective witness (T) between a thermoformed object (TO) and residual web (2a).
