Abstract
An apparatus includes a welding assembly which forms a seam in a tubular can body. A coating assembly applies coating material to an inner side surface of the seam. Coating material is conducted to the coating assembly through a main conduit. A monitor assembly, in the main conduit, includes a housing having an inlet valve and an outlet valve. An orifice is disposed within the housing between the inlet and outlet valves. A transducer senses fluid pressure downstream from the orifice. The inlet and outlet valves are operable to direct the coating material flow to and from a bypass conduit. This enables the orifice and/or the transducer to be repaired or replaced without interrupting operation of the coating assembly. In one embodiment of the invention, the monitor assembly is disposed ahead of the welding assembly and coating assembly. In another embodiment of the invention, the monitor assembly is disposed between the welding assembly and the coating assembly. A valve in a coating material return conduit may be closed during the coating of cans and be open when the coating of cans is interrupted.
