Abstract
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.
