<p>66925-431 The present invention is a system for conditioning water based compounds such that consistent film weights can be applied to can ends. The system comprises a downstream regulator or alternatively a gravity feed supply tank connected to the compound supply, a pump connected to the opposite side of the downstream regulator or gravity feed supply tank, a filter and a heater connected between the pump and the lining nozzle, and a back pressure regulator connecting the exit port of the lining nozzle to the inlet of the pump. The preferred embodiment uses a double diaphragm pump and contains two pressure pulsation dampeners, one located downstream from the pump and the other located downstream from the back pressure regulator. The conditioning system of the present invention allows film weight control within +/- 5%. The preferred embodiment of the present invention provides even further control to within +/- 3%.</p> |
