Abstract

A method of delivering a glutinous substance from a cartridge to a brush comprises receiving the cartridge inside a sleeve through an inlet of the sleeve while a pressure cap, located proximate the inlet of the sleeve, is in an open position. The method also comprises moving the pressure cap, located proximate the inlet of the sleeve, into a closed position to sealingly couple the pressure cap with a trailing end of the cartridge and to sealingly couple a valve with a leading end of the cartridge. The method further comprises applying pressure to the glutinous substance in the cartridge through a pressure input of the pressure cap to urge the glutinous substance from the cartridge to the valve. The method additionally comprises rotating the brush and opening the valve to enable the glutinous substance to flow from the valve to the brush at least when the brush is rotating.
