PURPOSE:To make surface finish polishing performable irrespective of work thickness unevenness, by mounting a center table on an air spring and an inner roll on an air cylinder, respectively and performing pressure regulation and vertical displacement. CONSTITUTION:A grinding belt 5 is stretched across between a contact roll 3 and an idler roll 4, and a presser shoe 7 and a pinch roll 6 are set up in front and in the rear of this contact roll 3. An inner roll 8 is set up just under the pinch roll 6 and a center table 10 just under the contact roll 3, respectively, and a conveyor belt 70 is installed in contact of the backside with this table, thus a workpiece is conveyed. The center table 10 is supported on an air spring 11 and the inner roll 8 on an air cylinder 9, respectively, whereby each of them is made possible for pressure regulation and vertical displacement. Therefore, finish polishing can be made possible irrespective of thickness unevenness of the work being conveyed. |
