ABSTRACT:
Apparatus for carbonizing a tissue paper web has an improved inking section which permits tissue to be coated, with or without uncoated striped areas, at speeds up to about 3,000 feet per minute. A first doctor blade positioned upstream of a second doctor blade and an equalizer rod contacts the paper very lightly so as to remove some of the excess thickness of ink on the paper, thus reducing the amount of ink to be removed by the second doctor blade and the equalizer rod. The equalizer rod is made of hardened wire of a very small diameter, preferably about 0.047 inches, and is supported under tension in a shallow v-groove by a pair of chucks which are rotated together.
