<p>A press for thermoforming a thermoformable sheet material (9a) for obtaining at least one thermomolded object, which has a support base (2); a pair of female molds (4, 5) supported for rotation around a rotation axis on the support base (2), diametrically opposite with respect to the rotation axis (x-x), drive means (6) for the pair of female molds (4, 5), comprising a rotary motion source (37) designed to drive a power drive shaft (38) and transmission means (41) designed to transmit the motion from the power drive shaft to the pair of female molds (4, 5), whereby between power drive shaft (38) and female mold pair (4, 5) 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 (4, 5) into a molding position, and into a discharge position.</p> |
