Paper to be varnished is held by the two ends and passes under the round arm seen above the tray. This arm is carried on a sliding rod which is supported by spring and controlled by foot lever, after depressing the foot lever the paper is immersed in the varnish to a depth regulated by mild screw on the top of the rod. The paper is then drawn through and out of the varnish.
