Abstract
An improved low cost screen printing apparatus for printing on both flat and curvilinear objects. Two vertically aligned shafts support the printing head and, by following the pivotal motion of an arm, raise and lower the printing head relative to the object being printed with a straight vertical displacement, resulting from the controlled movement of the upper shaft cooperating with arcuate channels formed in the end supports. The squeegee assembly operates in a timed relationship with the raising and lowering of the screen head to alternately lower the squeegee and raise the flood bar for forcing ink through the screen in the print cycle and raise the squeegee and lower the flood bar to flood the screen on the return cycle. When the screen is in the raised position, the squeegee assembly and screen frame are selectively connectable to a reciprocating carriage, for printing either curvilinear or flat objects.
