Disclosed is a method for fitting or replacing dies in thermoforming equipment provided with a base, a supporting structure supported by the base, a supporting head for at least one counter-die supported by the supporting structure, a supporting table for at least one die supported by the base beneath the supporting head, actuation means for the head and for the supporting table to control a sequence of controlled insertion and withdrawal movements between the head and the supporting table to cause the at least one die to move relative to the corresponding counter-die, and feed means, for a sheet of thermoformable material for the at least one die, designed to operate synchronously with the actuation means and including a pair of longitudinal members to advance the sheet in a transverse direction with respect to the direction of relative movement of the at least one die, the method comprising withdrawing the longitudinal members into a waiting position, laterally displacing the at least one counter-die closed against the at least one die in a direction transverse to that of the longitudinal members, and advancing the longitudinal members from the waiting position to a working position. Also disclosed is thermoforming apparatus as described above. |
