<p>A paint roller assembly comprises a tube (12) with a roller rotatably mounted thereon. Paint is introduced into the interior of the roller via tube (12) and passes radially outwardly through passageways (35A-G) in the roller to a cover (77). Leakage of paint between the tube (12) and the roller is inhibited by a sealing arrangement which comprises a diaphragm (59) fast with the roller and with a ring (58) rotatably mounted on tube (12). A seal (57) is mounted on the flange (61) and is biased against a seal (54) abutting one side of a flange (32) fast with the tube (12). Bias is provided by a spring (63) (or a resilient spring bellows diaphragm (80) (Figure 7)). The reaction force of the spring acts on the roller and biases a seal (50) on the roller against a seal (51) abutting the other side of the flange (32). </p> |
