A method and apparatus for zone controlling the temperature of a rotating roll. The apparatus (12) includes a roll (30) having a surface (32) at a first temperature and a belt (70) disposed adjacent at least a portion of the surface (32) of the roll (30). The belt (70) contacts the roll surface (32) in a contact region (C) and has a second temperature that is different from the first temperature of the roll (30) such that the belt (70) affects a temperature change in at least a portion of the surface (32) of the roll (30) in the contact region (C) as the roll is rotated.

L'invention concerne un procédé et un appareil permettant de réguler les zones de température d'un rouleau rotatif. L'appareil (12) comprend un rouleau (30) présentant une surface (32) à une première température et une courroie (70) disposée de manière adjacente à au moins une partie de la surface (32) du rouleau (30). La courroie (70) vient en contact avec la surface (32) du rouleau dans une région de contact (C) et possède une seconde température différant de la première température du rouleau (30), de manière à effectuer un changement de température dans au moins une partie de la surface (32) du rouleau (30) dans la région de contact (C) pendant la rotation du rouleau.
