ABSTRACT:
A multiple print head, automated screen printing machine is described with improvements for inspecting and cleaning a print screen. The print screen and its frame are locked securely in position within a print screen holder, which in turn is locked into a precise spacial relationship beneath a permanently installed print head frame. The rear edge of the print screen holder is hinged so that an operator can hand lift the holder upwards, or activate an air cylinder which causes the holder to pivot upwards at its front edge. Provisions are also made for moving the print carriage with associated squeegee(s) and flood bar(s) entirely away from the area occupied by the print screen holder. Print screen inspection and cleaning is accomplished without moving the print head frame, providing additional safety for operators during these maintenance procedures.
