Described briefly, according to a typical embodiment of the invention, a roller has a core comprising plurality of relatively hard and rigid segments fastened together in a stack and rotatably mounted to a shaft. The roller core has internal baffled passageways established by grooves in abutting faces of segments, so that, when paint is supplied to a cavity in the center of the stack, it will depart through these passageways in the roller in a controlled manner. A diaphragm seal assembly is provided to prevent leakage of pressurized paint. A replaceable sock-like cover is received on the roller stack and secured by end retainers. The roller can be easily and completely disassembled for cleaning.
