ABSTRACT:
Provided is an apparatus for cleaning a rubbing-cloth. The apparatus includes a rubbing-cloth fixing unit, a pile removing head, and a transferring unit. The rubbing-cloth fixing unit is fixed to a base body and fixes a rubbing-cloth that is substantially unfolded. The pile removing head is disposed on the rubbing-cloth fixing unit and sucks and removes the piles attached onto the rubbing-cloth. The transferring unit is fixed to the base body and transfers the pile removing head along an upper surface of the rubbing-cloth with respect to the rubbing-cloth fixing unit. Accordingly, particles that are generated when a rubbing-cloth is cut out from a fabric are quickly removed from the rubbing-cloth, so that scratches may be prevented from being generated on an alignment film.
