PURPOSE:To permit the uniform traveling of a polishing belt by preventing the generation of creases in a dewatering part and the slip of a polishing belt by driving supporting rollers in all-wheel drive and providing the driving turning moment for the dewatering roller which is press-attached onto the polishing belt. CONSTITUTION:Each supporting roller 7, 8, 9 is all-wheel-driven through chains 34 and 28 by the drive of a driving motor M1, and a polishing belt 10 wound onto these supporting rollers 7, 8, and 9 is traveled. Further, a dewatering motor M2 is revolution-driven in proportion to the driving motor M1 by a drive controlling mechanism, and a dewatering roller 16 is compulsorily revolved through a chain 37, and also in the dewatering part, the polishing belt 10 is traveled in the tension state, and generation of creases in the dewatering part is prevented, and the slip of the polishing belt 10 is removed by the all-wheel driving of the supporting rollers. |
