Abstract
A nozzle cleaning device is provided comprising a support structure capable of releasably receiving a hollow nozzle body having an inner surface and an open end or terminal edge portion, and a scraper apparatus coupled to the support structure and including at least one scraper finger adapted to move into and out of the nozzle body. The scraper finger has a distal end and a camming surface extending from the distal end to a scraping edge. The camming surface engages the nozzle body terminal edge portion as the scraper finger moves into the nozzle body, and the scraping edge engages the nozzle body inner surface as it moves within the nozzle body so as to remove unwanted material from the nozzle inner surface.
