Abstract

"AQUECIMENTO DE SUPERFìCIES DE ROLOS DE CALANDRA" Trata-se de um processo e um aparelho para o rápido aquecimento de rolos de calandragem (350, 352) para um aparelho de calandragem (200). Em uma área de aquecimento (800), os rolos (350, 352) são pré-aquecidos, reaquecidos ou mantidos a qualquer temperatura antes da colocação dos rolos (350, 352) no aparelho de calandragem (300). O processo preferido de aquecimento é por aquecimento por indução. Os rolos (350, 352) podem ser distribuídos para o aparelho de aquecimento (802) a partir de uma área de armazenamento inicial (420) ou do aparelho de calandragem (300). Os rolos (350, 352) são transportados por um mecanismo de transferência suspenso (400). O processo e o aparelho apresentados facilitam consideravelmente a formação de laminados de várias camadas e são particularmente úteis na técnica de formação de pneus."HEATING OF CALENDER ROLLER SURFACES" This is a process and an apparatus for rapidly heating calender rolls (350, 352) for a calendering machine (200). In a heating area (800), the rolls (350, 352) are preheated, reheated or maintained at any temperature before placing the rolls (350, 352) in the calendering machine (300). The preferred heating process is by induction heating. The rolls (350, 352) can be distributed to the heating device (802) from an initial storage area (420) or from the calendering device (300). The rollers (350, 352) are transported by a suspended transfer mechanism (400). The presented method and apparatus considerably facilitate the formation of multilayer laminates and are particularly useful in the tire-forming technique.
