In this lamination process, up to four sheets of paper are laminated at one time by a press, from either 19'/1," or 241/x" rolls, depending upon which width is being made. The adhesive agent is 1290Y Wax. The consumption of wax when running at full speed is 100 lb. in 15 minutes. Wax is held at melting temperature in supply tank, and poured into the machine tank as needed. The tanks had been heated by gas which was unable to maintain wax temperature, particularly when press was operating at full speed. Also, the non-uniform heating caused the viscosity of the wax to vary, resulting in fluctuating thickness of coating on the paper.- Electric Immersion Heaters were placed in the tanks. They were simply "dropped" into the tank with the terminal housing resting over the side.
