ABSTRACT:
A nip roll presses a hot, rapidly moving, endless printed and dried paper web into intimate contact with the exterior surface of a first downstream chill roll so as to improve the cooling efficiency of the first downstream chill roll, permit the use of fewer chill rolls, and prevent condensate streaking. The nip roll is specially designed to press the web into intimate contact with the first downstream chill roll while avoiding damage to the web, nip roll, or chill roll, and while avoiding ink picking on the web surface contacted by the nip roll. The nip roll has an elastomeric outer peripheral surface and is internally cooled so as to maintain the outer peripheral surface at an equilibrium temperature below that at which ink softening and resultant picking could occur. By eliminating concerns of condensate streaking, the nip roll also permits dryer operation at relatively low temperatures, thereby substantially reducing operating costs.
