ABSTRACT:
A spray cleaning apparatus for cleaning the surface of a caul screen includes at least one cleaning head assembly having a cleaning head in fluid communication with a pressurized fluid source. The cleaning head has an upstream end and at least one outlet nozzle in fluid communication with the upstream end, and which are operable to direct a generally linear high pressure fluid stream onto the surface of the caul screen. The cleaning head assembly is moveably mounted on a support beam so as to be maintained a substantially fixed distance from the caul sheet. A conveyor reciprocally moves part of the sheet beneath the cleaning head assembly, with the cleaning head being indexed in movement along the support to successively reposition cleaning fluid flow relative to the sheet.
