Abstract
An inside wall of an elongated syringe body is coated by supplying at least an outer surface of an applicator ring with a coating of silicon oil while displacing a rod carrying the coated ring from a rear end to a front end of the body with the ring in continuous annular engagement with the inside wall thereof so as to transfer the oil from the ring to the inside wall. Thereafter a scraper ring also carried on the rod is displaced from the front end to the rear end of the body with the scraper ring in continuous annular engagement with the inside wall so as to scrape excess silicone oil from the inside wall.
