Abstract
A drying/curing apparatus for a rotary screen printing machine includes a carriage supporting a flash curing unit. The curing unit has a height or thickness that is less than the gap between the workpiece platen of the printing machine and the printing screen. The drying apparatus includes a structure attached to a print station of the printing machine that is configured to permit reciprocation of the curing unit across a substrate supported on the workpiece platen after an ink layer has been applied to the substrate and the platen has been retracted from the print screen. The curing unit includes a plurality of heat generating elements, such as high power quartz lamps, that are directed toward the ink layer on the substrate. The curing unit includes an insulator plate disposed between the curing lamps and the printing screen of the printing machine when the curing unit travels across the workpiece platen. In addition, the curing unit includes a number of channel shaped reflector elements mounted to the underside of the insulator plate with the curing lamps disposed within the reflective channel. Adjacent reflector elements are spaced apart to define a ventilation gap or channel th…
