off the back and as the drum comes around toward the proper position for impression, the arm begins its forward sweep and takes the top sheet with it, shoving it between the roller and the drum. As soon as the sheet is making contact, the drum begins its pull and moves the sheet on from there while the feeder arm reverses its travel and begins dragging back over the stack to prepare to shove another sheet forward. It is important that the rubber tips on the feeder arm fingers be given a good deal of attention. They are necessarily rough, and as they wear smooth their efficiency lessens. When they get smooth they should be rotated and a new surface exposed to use. [When you run out of rough surfaces, the rubber tips may be abraded by rubbing them with the jaws of a pair of pliers, or even with your thumb. Often the smoothness on the rubber is due to an accumulation of oil from the ink. -- Ed.] In like manner the sponge rubber tension pads should be kept free of lint and as they wear should be adjusted or replaced. point. [a very important/ to remember is that before stacking fresh paper in the feeding mechanism, you should ruffle them, making sure that each sheet is separated from its neighbor. This prevents them from binding and lessens the chances of feeding more than one sheet through at a time. Ed. ] VI. SLIP SHEETING: When the paper does not absorb the ink fast enough, and one wishes to keep all trace from appearing on the back side of the next sheet, it is necessary to slip sheet. This is accomplished by laying a sheet of paper or other material over each sheet as it falls into the catcher, thus preventing the sheets from coming into contact with each other. Regulation slip sheets are the easiest to handle, but are rather expensive. They are designed to operate in automatic equipment that drop a slip sheet each time a duplicated sheet drops into the catcher. This special size and design are the cause of the extra cost. After the run is completed the duplicated material with slip sheets still between is stacked somewhere to dry. This drying process may take anywhere from a few minutes to several days. The absorbing qualities of the paper and the weather set the limits. Coated bond paper takes the longest, and the writer has experienced a wait of three days during damp weather, and even then thought the sheets should have waited longer. When dry, the sheets and slip sheets are separated, restacked, and the back side may be run if the publisher so desires. Subsequent chapters in this series are in progress and will appear.
