Machine for the formation of alveoli in sheets of hot deformable and cold stabilizable plastic material, whose machine comprises a drum that has a series of dies that cooperate with suction or pressure devices; being characterized by the fact that said machine comprises a second drum whose axis is parallel to the first and which is animated by a continuous rotation movement, in synchronism with the rotational movement of the die-holding drum; the second drum having holes whose dimensions correspond substantially to the dimensions of the honeycomb or parts of the dies through which an intense heat radiation passes, coming from a fixed heating device, mounted inside the second drum, in a place close to its periphery, sensibly on the line of unión of the centers of rotation of the two drums, to cause an almost instantaneous intense heating of the sheet of plastic material, while the full parts of the second drum hide the parts of said sheet in contact with the periphery of the matrix to subtract said parts from the action of the heat radiation.
