Zusammenfassung:A pad of flexible and resilient material for hand smoothing surfaces by abrasive paper has inside a fluid passage in communication with the outside by means of a sleeve connected, through a hose, with a vacuum source or a fluid feed, as well as with several through holes on the lower processing surface. In case of air suction also some vent holes are provided to the outside, having a smaller cross-section area with respect to the actual suction holes and within said passage, immediately after said connection with the outside, there is formed a vacuum balance chamber.
