Abstract
Provided are buffing pads that have intertwined seams such that any hard or unyielding edges are covered and not exposed during a buffing or polishing process. A double-sided buffing pad for polishing surfaces comprises a backing plate; two fibrous buffing media with filaments of textiles extending therefrom that are affixed one media to each face of the backing plate; and a seam that is intertwined by a portion of the filaments from each media are intertwined. The filaments may be intertwined by needle-tacking, air entanglement, or hydro-entanglement.
