ABSTRACT:
In a screen printing machine having a plurality of workpiece supporting pallets that are driven along an oval path and which cooperate with a plurality of printing heads that are adapted for movement between an operative, printing position at each of a plurality of printing stations and an inoperative, non-printing position spaced from each of the printing stations, means are provided for selectively indexing the pallets either to an immediate printing station or to a succeeding printing station which is spaced downstream from the preceding printing station in the direction of movement of the pallets by at least one intermediate printing station. The apparatus disclosed herein replaced the hydraulic and electrical apparatus of the prior art with mechanical structure and requires only a single operator as compared with two or three operators with prior art structure. A cable is used in the present invention to replace the power linkage employed in the prior art for raising and lowering the flood bar.
