ABSTRACT:
A headbox for a paper-making machine includes an inlet for receiving a fiber suspension and an outlet for discharging the fiber suspension. The headbox has a plurality of walls including an apron and a pair of side plates. The side plates are disposed at opposite ends of the headbox. The apron is comprised of steel. A beam extends between the side plates and includes opposite ends. Each end is disposed a predetermined distance from a respective side plate when at an ambient temperature (approximately 70.degree. F.). The beam is comprised of steel. A slice lip is carried by the beam. The slice lip is positioned at the outlet and includes a working edge defining an outlet gap with the apron. The slice lip has a pair of longitudinal ends, with each longitudinal end being disposed a predetermined distance from a respective side plate when at the ambient temperature. Each longitudinal end includes a slot extending from and substantially orthogonal to the edge. The slice lip consists essentially of titanium. A pair of seals are disposed in respective ones of the slots and seal between a respective longitudinal end of the slice lip and a respective side plate. Each seal is comprised of a non-woven, porous material.
