<p>Automatic apparatus for screen printing on textiles on a long table. A travelling carriage is pneumatically driven stepwise on rails and guided by guide-wheels cooperating with guide rails. A printing frame having a screen thereon is transported by the carriage. The frame is lowered automatically to apply the screen to the surface, such as a fabric, on which printing is to be effected. A squeegee is operated automatically applied under pressure to the screen and a doctor blade is reciprocably driven to effect inking and printing on the fabric surface. The carriage transports a valve system that sequences intermittent stopping of the carriage and while the carriage is stopped effects automatic lowering of the frame and screen, lowering of the squeegee, the forward and backward movement of the doctor blade, stopping of the blade, and sequential lifting of the squeegee and frame and advancement of the carriage to its next stop position where the above steps are again effected.</p> |
