Abstract
Continuous, automatic printing of ordinary fabrics and cloths and screen printing of papers, films, metal foils and metal sheets is disclosed. Printing is accomplished by contacting a squeegee member, to which the printing paste or ink has been applied, with the material to be printed through a flat screen (stencil). The material to be printed is fed continuously at a constant speed in a supported state to a printing operation zone. The flat screen is reciprocated in the longitudinal direction at the same speed and in the same direction and in contact with the material to be printed. The squeegee is scanned from one end of the flat screen to the other to effect the printing operation. The contact between the flat screen and material to be printed is released just before the squeegee member arrives at the other end of the screen. The screen and squeegee member are then moved to their original position so that the operation may be repeated. The flat screen and squeegee member are driven by a common drive source and the operations of transporting the material to be printed, the flat screen and squeegee member as well as the operations of contacting and breaking the contact between the…
