The present invention relates to one kind of pressure apparatus for hot pressing the processed material to form, and the pressure apparatus has one processed material supporting structure to support the introduced processed material with less displacement. The pressure apparatus possesses one support structure to hold the processed material between heating discs and with one pair of ring belt structures, each of which includes one ring belt for the processed material to be set on and one pair of belt wheel for the ring belt to be hung on. After processed material is set on the ring belt, the upper part of the ring belt and the processed material may be moved forwards and backwards in the material conveying direction. |
