Abstract:
[Problem] To prevent pressurizing fluid contained in a pressurizing chamber from leaking from a sealing section. [Solution] In a double belt press, a sealing section that seals a pressurizing chamber has an inner seal, an outer seal, and a partition wall section. The inner seal has an inner seal flow passage, at both ends of which there are formed an inlet for taking in sealing fluid supplied to an inner seal groove and a jet for jetting the sealing fluid taken in from the inlet toward a belt. The outer seal has an outer seal flow passage, at both ends of which there are formed an inlet for taking in sealing fluid supplied to an outer seal groove and a jet for jetting the sealing fluid taken in from the inlet toward the belt. In the partition wall section, a plurality of fluid supply passages that supply sealing fluid to the inner seal grooves and the outer seal grooves, and a plurality of fluid recovery passages that recover sealing fluid accumulated in the space formed between the inner seal and the outer seal, are provided at different positions in the direction along the outer edge of the pressurizing chamber.
