Title
(EN) HEATING OF CALENDER ROLL SURFACES
(FR) CHAUFFAGE PAR INDUCTION DE SURFACES DE ROULEAUX DE CALANDRE
Abstract
(EN)
A method and apparatus for rapid heating of calender rolls (350, 352) for a calendering apparatus (200) is disclosed. At a heating area (800), the rolls (350, 352) are preheated, reheated, or maintained at any temperature prior to the rolls (350, 352) being placed into the calendering apparatus (300). The preferred method of heating is by induction heating. The rolls (350, 352) may be delivered to the heating apparatus (802) from an initial storage area (420) or the calendering apparatus (300). The rolls (350, 352) are transported by an overhead transfer mechanism (400). The disclosed method and apparatus greatly facilitate formation of multi-layered laminates and is particularly useful in the tire building art.

L'invention concerne un procédé et un appareil de chauffage rapide des rouleaux de calandre (350, 352) pour un appareil de calandrage (200). Dans une zone de chauffage (800), les rouleaux (350, 352) sont préchauffés, réchauffées ou maintenus à une température quelconque avant leur insertion dans l'appareil de calandrage (300). Le chauffage s'effectue par induction. Les rouleaux (350, 352) peuvent être acheminés vers l'appareil de chauffage (802) à partir d'une zone de stockage initiale (420) ou l'appareil de calandrage (300). Les rouleaux (350, 352) sont transportés par un mécanisme de transfert suspendu (400). Le procédé et l'appareil facilitent considérablement la formation de feuilles multicouches et conviennent particulièrement à la fabrication de pneus.
