Vertical rotary screen printing machine and ink supply therefore

A rotary screen printing machine comprising;

• a frame including a plurality of screen printing cylinders, means for superimposing said printing cylinders in a vertical arrangement one above another on said frame;
• a dye dispensing bar and squeegee arrangement extending through each said printing cylinder and including a hollow bar extending therethrough and projecting beyond the ends thereof;
• spaced platforms for said each cylinder;
• a first bearing slidably mounted on one said platform and rotatably mounting one end of said hollow bar;
• a second bearing slidably mounted on the other said platform and mounting the other end of the hollow bar;
• a squeegee blade mounted along the hollow bar for contact with the internal surface of the corresponding printing cylinder;
• a plate supported along the hollow bar to define with the squeegee blade a dye liquor weir in communication with the hollow bar interior via metering passage means;
• means connected to one of said ends of the hollow bar for controllably feeding dye liquor into the hollow bar interior and from thence via said metering passage means and weir to the printing cylinder internal surface;
• means on each said platform and connected to each bearing for sliding the latter along the platforms radially towards or away from the internal surface of its corresponding printing cylinder to vary the contact pressure between the squeegee blade and each said printing cylinder and adjustment means interconnecting the second bearing and the hollow bar for pivoting the hollow bar about its own axis and locking the same in adjusted angular position to thereby control the amount of dye liquor egressing from the weir radially towards the corresponding printing cylinder internal surface.
