Abstract
A thermoforming apparatus is provided having a frame, a pair of opposed platens, a toggle shaft, a kinematic linkage, a form air manifold, and a pair of articulating bearing assemblies. The pair of opposed platens is carried by the frame each with a die, one die configured to engage an opposed face of another die across a heated sheet of thermoformable material in sealed relation there between. The toggle shaft is carried by the frame for rotation. The kinematic linkage is coupled between the toggle shaft and one of the dies. The form air manifold and a source of differential pressure is coupled with a die face on one of the dies. The pair of articulating bearing assemblies is carried by the frame and configured to support the at least one toggle shaft for translation towards and away from the another die and platen. A method is also provided.
