ABSTRACT:
Adjustable tube-cleaning device (10) has a scraper sub-assembly (16) which includes a substantially annular sleeve (32) on a circumferential outer surface (30) of an elastic core (14) which, in turn, is mounted on a central shaft (12). The sleeve (32) contracts toward a pre-formed, non-loaded configuration in which it has a smaller internal diameter than a diameter of the outer surface of the elastic core. The scraper assembly further includes a plurality of scrapping vanes (32) held by the sleeve to the elastic core and extending radially outwardly from the elastic core. Each of the scraping vanes has a scraping edge (54) directed radially away from the elastic core. The elastic core is substantially cylindrical and surrounds the central shaft between anchor (18) and adjustable compression member (26). The scraping vanes in one row of vanes can be placed on an angle relative to a plane perpendicular to an axis of the central shaft.
