ABSTRACT OF THE DISCLOSURE A calendering apparatus is disclosed for hot-calendering a paper web. The apparatus includes a rotatable calendering roll defining a smooth calendering surface. A backing roll rotatably cooperates with the calendering roll for defining therebetween a calendering nip for a e passage therethrough of the web. An induction heater is disposed in close proximity to the calendering surface nip for inducing eddy currents within the calendering roll such that the calendering roll is heated. The blow box is disposed in close proximity to the calendering surface and between the heater and the nip. The blow box defines a plurality of compartments which are disposed in a cross-machine direction. Each of the compartments selectively blows a current of cooling air against the calendering surface for controlling the temperature of the calendering surface so that the temperature of the calendering surface adjacent to the nip is controlled in a cross-machine direction.
