Thereby, the pressurizing fluid 6 is prevented from flowing out to the outside, and a gap is formed between the endless steel belt 2 and the peripheral edge portion 8a by the knoll fluid 7. Therefore, the endless steel belt 2 is transported without contacting the peripheral edge 8a. Note that the knoll portion 5 is drawn large in the figure for convenience of explanation, or is actually about 0.1 mm to 0.1 mm.

Therefore, excessive frictional force is not applied to the endless steel belt 2 or the pressurizing chamber 4. Therefore, the endless steel belt 2 can maintain a good polished surface for a long period of time, making it possible to perform extremely excellent pressure processing.

生ずる等の不都合があった。[Problems to be Solved by the Invention] However, the continuous pressurization method described above still has the following drawbacks. That is, when pressurizing the pressurizing chamber 4 by heating or cooling it, a temperature difference occurs between the pressurizing chamber 4 and the housing 8 and the fixed frame 10, and deformation of each part of the machine due to the difference in thermal expansion occurs. . In particular, since the fixed frame 1o is usually stronger than the housing 8, distortion occurs in the pressurizing chamber 4. As a result, the gap between the seal portions 5 is no longer constant, making it impossible to obtain a sufficient sealing effect. Further, there were other problems such as wasteful loss of the sealing fluid 7.

Even if the pressurizing chamber 4 becomes high temperature, the temperature of the housing 8 is kept relatively low, and the temperature difference between the temperature 'J'1 of the fixed frame 10 and the temperature T2 of the housing 8 (') is maintained at a small value. Therefore, thermal deformation due to the temperature difference (T2-'Fl) can be suppressed.
