Double-belt press

Pressurizing fluid accommodated in a pressurizing chamber is prevented from leaking from a sealing part. In a double-belt press, a sealing part for sealing a pressurizing chamber has an inner seal, an outer seal, and a partition wall part. The inner seal has an inner seal flow path in which a suction port for sucking in the sealing fluid supplied to the inner seal groove and a discharge port for discharging the sealing fluid sucked in from the suction port to the tape are formed at both ends. The outer seal has an outer seal flow path in which a suction port for sucking in the sealing fluid supplied to the outer seal groove and a discharge port for discharging the sealing fluid sucked in from the suction port to the tape are formed at both ends. And a partition wall portion, a plurality of fluid supply channels for supplying a sealing fluid to each of the inner seal groove and the outer seal groove, and a plurality of fluid recovery channels for recovering the sealing fluid accumulated in a space formed betwe
