ABSTRACT:
This apparatus for applying a pasty or similar product by means of a rotary coating pad carried by a cartridge comprises a motor for driving this cartridge through gears. The cartridge encloses a piston adapted to slide freely in the cartridge bore and pneumatic or other means, preferably a pump, are incorporated in the apparatus case for exerting a pressure against the inner end of the piston and thus force the product out through the coating pad. This pad has a two-portion structure so that the cartridge can easily be filled or refilled through this pad, the apparatus being particularly but not exclusively suited for applying boot-polish or like products.
