| 摘要 |
The present invention is applicable to grinding apparatus for removing irregularities from and for levelling the working surface of thick, large width rubber belts used to compact paper or (in the case of fabric, preshrink) fibrous webs; and the control of such grinding apparatus. The present invention permits grinding during production use of a belt when the environment near (above) the belt is inimical to visual grinding control by personnel due to high heat and steam. Sensing and control means placed remotely from the working surface of the belt permits an operator to control grinding more precisely than if done visually and without subjecting the operator to dangerously adverse working conditions.
