Definitions
- the present invention relates to a press belt and a shrew press ronole used for pressurizing a press object in various industries such as the paper industry, the magnetic recording medium manufacturing industry, and the textile industry.
- a belt-like press object is placed on a press belt, and between one pressure member located inside the circumference of the press belt and the other pressure member located outside the circumference of the press belt.
- a belt press that pressurizes the object to be pressed is used.
- the pressurizing member is a press roll, a force and pressure shear, or the like.
- a shrew press as a dewatering press in the paper industry can be mentioned.
- a simple press is briefly explained by taking the paper industry as an example.
- a press roll as an external pressure means positioned outside the circumference of the press belt, and an internal pressure means as located inside the circumference of the press belt.
- pressure is applied (dewatering treatment) by applying surface pressure to the press object (wet paper) placed on the outer peripheral surface of the press belt through the press belt.
- a roll press that presses with two rolls applies a linear pressure to the object to be pressed, while a shush press uses a pressure shear with a predetermined width in the running direction to cover the surface pressure on the object to be pressed. I can. For this reason, when the dehydration press is performed by a press press, there is an advantage that the dip width can be increased and the dewatering efficiency can be increased.
- a shrew press may be performed instead of the roll press or in combination with the roll press.
- Typical required properties for press belts include strength, wear resistance, flexibility and impermeability to water, oil, gas and the like.

- a shoe belt is disclosed which has improved wear resistance and crack resistance by changing to a lower level. In this case, it is considered that there is an effect that the wear resistance and the pressure deformation resistance are maintained in the central area, and cracks are likely to occur in both edge areas.
- Japanese Patent Laid-Open No. 10-298893 is based on such a concept.
