Abstract: A press for thermoforming a thermoformable sheet material for obtaining at least one thermomolded object, which has a support base; a pair of female molds supported for rotation around a rotation axis on the support base, diametrically opposite with respect to the rotation axis, drive means for the pair of female molds, comprising a rotary motion source designed to drive a power drive shaft and transmission means designed to transmit the motion from the power drive shaft to the pair of female molds, whereby between power drive shaft and female mold pair there is an angular displacement ratio of an angle greater than 360°, preferably 405°/180°, in order to make the female mold pair complete a sequence of 180° angular travels, thereby angularly and sequentially move each female mold into a molding position, and into a discharge position.

Abstract: The present disclosure 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 thermof
