Abstract
In an automatic wet sanding apparatus including a paper peeling unit that has a clamping shaft and a clamping hook, an inclination angle of a leading end surface of the clamping hook is equal to an inclination angle of an outer circumferential surface of a cushion pad at the start of a paper peeling step. Thus, the leading end surface of the clamping hook comes into contact with an outer circumferential end of a disc at the same time as coming into contact with the outer circumferential surface of the cushion pad, so that the cushion pad is less likely to get caught due to deformation of the outer circumferential surface and its peripheral part of the cushion pad. It is therefore possible to appropriately remove the sandpaper from the cushion pad and stably perform the task of removing the sandpaper.
