Abstract

There is provided a paper machine, characterized by a press device including a press mechanism which pressurizes wet paper to squeeze water therefrom, and a pair of endless paper conveying belts for pinching and conveying the wet paper as well as absorbing water squeezed from said wet paper, and a polishing device having a polisher to polish the wet paper contacting face of a belt in order to control the surface smoothness of the wet paper contacting face of the belt on the return side of at least one of the paper conveying belts at such a position that the wet paper contacting face of the belt, which is running, can be polished. The paper machine maintains a smooth wet paper contacting face of a paper conveying belt and a good paper peeling performance.

Description

technical field [0001] The invention relates to a paper machine and a repair method for a paper transport belt. In particular, the present invention relates to a paper machine provided with a polishing device which restores the deteriorated wet paper peeling characteristics of a paper transfer belt or suitably modifies or The roughness of the surface of the transmission belt is repaired, and the invention also relates to a method for repairing the paper transmission belt by using the polishing device. Background technique [0002] Paper machines generally include a wire section, a pressing section, and a drying section. The screen section, pressing section, and drying section are arranged in the above order along a conveying direction of a wet paper. The wet paper is conveyed by being transferred by the paper conveying means provided in the respective parts of the screen part, the pressing part, and the drying part, and at the same time, water is squeezed out (water is ext...
