A heating plant (10) for thermoformable porously structured material (13) comprises a pair of superimposed plates (11,12) designed to receive between them the thermoformable material to be heated. The plates being relatively movable towards each other to mutually approach the material placed between them with each plate having surfaces in contact with the material which is pierced with one plate emitting (12) through the holes a heated air flow and the other plate (11) sucking the air flow through the holes. In this manner a hot air flow is established through the material placed between the plates to accomplish fast and thorough heating of the material in the entire mass to make it ready for pressing. <IMAGE> |
