摘要： A method for producing a groove pattern on a cylinder surface includes providing an abrasive module, including an abrasive mesh article and collector block, providing a patterning head, which including the abrasive module and pressing actuator, pressing the abrasive module against the cylinder surface by using the actuator, forming a plurality of grooves on the cylinder surface by causing relative motion between the abrasive module and cylinder surface, and drawing gas through the abrasive mesh article to collect particles released from the cylinder surface. The abrasive mesh article includes a plurality of abrasive grains bonded to a flexible mesh backing, defining openings. The collector block has a curved supporting surface defining openings. The abrasive mesh article is attached to the curved supporting surface by a releasable fastening system. The openings of the flexible mesh backing are in communication with the openings of the collector block via the releasable fastening system.

摘要： A continuous abrasive product includes predetermined length and number of predetermined kind of abrasive areas on an abrasive surface, A method for abrading a workpiece, includes arranging an abrasive area of an abrasive product at an abrading zone for abrading the workpiece, and after abrading, replacing the abrasive area at the abrading zone with an another abrasive area of the abrasive product for abrading the workpiece according to a subsequent abrading phase. The used abrasive area is replaced by an unused abrasive area of a different kind. The abrasive product comprises a continuous longitudinal abrasive material including at least two longitudinally sequential different abrasive areas having different kind of abrasive properties.
