Abstract
An apparatus and method for inspecting a rubbing-cloth is provided. The apparatus for inspecting a rubbing-cloth includes: a base-platform provided with a pressure-sensing device on a surface thereof; a supporting-frame; a rubbing-roller, rotatably supported above the surface of the base-platform by means of the supporting-frame, with a rubbing-cloth wrapped around an outer circumference of the rubbing-roller; when the rubbing-roller is rotated, the rubbing-cloth rubs the surface of the base-platform, and the pressure-sensing device can detect pressure-sensing signals of pressure applied by the rubbing-cloth at each of detection-points on the surface of the base-platform.
