Abstract: A flexible abrasive member including a substrate, which carries an array of deposits with embedded abrasive particles, where each deposit has an elongated continuous structure that extends along a center trajectory predominantly in a longitudinal direction across the substrate. The structure has inset portions and recessed portions, which protrude oppositely along a transverse directions from the center trajectory. The inset portions of a deposit are accommodated in the recessed portions of a transversely preceding deposit, and the recessed portions of the deposit accommodate the inset portions of a transversely following deposit, so that the inset portions and recessed portions of neighboring deposits mutually overlap in said transverse directions.

Abstract: A treatment article (1) for rotational surface treatment of an object, such as an object of e.g. stone, wood, linoleum, concrete, terrazzo and the like, includes a pad (2) having major surfaces (3, 4) facing away from each other and a plurality of flaps (6) connected to one (3) of the major surfaces of the pad. The flaps cover the pad and overlap each other in the circumferential direction of the pad (2). Also, the flaps (6) are each attached to a support layer (5) interposed between the pad (2) and the flaps (6).
