A multi-stage roll type sheet molding apparatus includes four or more molding rolls including a touch molding roll, a main molding roll and finish molding rolls disposed in the horizontal direction in parallel to each other, in which a molten sheet is supplied downward from above to a first nip part interposed between the touch molding roll and main molding roll, the sheet is compressed by the molding rolls, and the compressed sheet is windingly fed sequentially from the main molding roll to the finish molding rolls, thereby molding a sheet having a specific thickness. The apparatus further includes a rear-stage side rail for guiding the finish molding rolls in a horizontally movable manner and second to fourth hydraulic cylinders for horizontally moving the finish molding rolls to in such a manner that they can pressurize the sheet.

Multi-stage roll type sheet molding apparatus

A device and a method for continuous high-pressure treatment; the method, comprising the steps of increasing the pressure of raw materials ( ) in a feed tank ( ) by a pressurizing pump ( ) so as to continuously feed the raw material to treatment containers ( ) and ( ) and increasing the flow rate of the pressurizing pump ( ) over that of a depressurizing pump ( ) or continuously exhausting the raw material from the treatment containers ( ) and ( ) through a pressure regulating flow path resistance ( ) while depressurizing; the device, comprising pressure releasing bypass circuits ( ) disposed in the flow path resistance ( ) in parallel with each other, wherein the insides of the treatment containers ( ) and ( ) are kept in a specified high-pressure state during the continuous processing.
