ABSTRACT:
A flood bar actuator for initiating the flood cycle in a universal screen printing machine is described. The squeegee assembly is mounted for vertical movement relative to the screen. The flood bar assembly is mounted adjacent the squeegee assembly, with an inner end fixedly mounted to an accessory support, and an outer end pivotally attached to the inner end. A peg extending from the squeegee assembly forces the flood bar up in the print cycle and allows the flood bar to drop onto the screen during the flood cycle. The height of the flood bar is adjustable through the rotation of the screw seated in an opening formed by a split support block forming the opening. A first half of the split support block is pivotally attached to the inner flood bar support as described, while the flood bar is supported from the second movable half. This second movable half has a threaded channel formed in its walls while the first channel has smooth walls. With this structure, on the rotation of the screw, the second half will be vertically moved relative to the first half for adjustment of the height of the flood bar relative to the screen.
