    • 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.
    • 用于在长桌子上纺织品上进行丝网印刷的自动装置。 行走架在轨道上逐步气动驱动,并与导轨配合导轨引导。 具有屏幕的打印框架由托架运输。 框架自动下降以将屏幕施加到要进行打印的表面,例如织物上。 刮刀在压力下自动施加到筛网上,并且刮刀可往复地驱动以在织物表面上进行着墨和印刷。 托架运送顺序间歇停止滑架的阀门系统,并且当滑架停止时,可以自动降低框架和筛网,降低刮板,刮刀的向前和向后运动,刀片停止,以及顺序 提升刮板和框架,并将托架前进到其再次进行上述步骤的下一停止位置。
