A rubbing machine and its tool pan are disclosed. The tool pan (122) comprises a number of homocentric annular structures (125) which have a lot of rubbing zones (121). Provided between the contiguous rubbing zones is at least a ramp (127), which is extending along the normal of the tool pan, and the height of which is increased gradually towards the fringe of the tool pan. In the rubbing machine (100) the tool pan is used. The rubbing machine is applicable in paper making industry, and can effectively separate and fibrillate the fiber of herbage by mechanical force between a pair of tool pans, thereby needing not to use chemicals, and according with the modem conception of environmental protection. |
