<p>The system comprises a rotatable sealant supply chamber means (50) for holding a supply of sealant for delivery to one or more conventional dispensing head means (52)(53) through conventional supply hose means (54), (55). A spindle means (56) and conventional bearing means (58) enable rotation of supply chamber means (50) relative to a conventional non-rotatable support housing means (60). Sealant is periodically supplied to supply chamber means (50) from a large-size supply container means (62) through a conventional pump means (64), a conventional solenoid valve means (66) and supply tube means (68) mounted in and extending through support housing means (60) and spindle means (56) into supply chamber means (50). Pressurized air is continuously supplied to sealant supply chamber means (50) from a conventional air supply source (70) through a conventional pressure regulator means (72) and supply passage means (74) in and extending through spindle means (56) and support housing means (60) to chamber means (50). Three level sensor means (76) (78) (80) are mounted in sealant supply chamber means (50) and connected to a conventional electrical control means (82) which controls pump means (64) and solenoid valve means (66) to maintain a supply of sealant in the chamber means (50) between a maximum level (86) and a minimum level (88).</p> |
