Zusammenfassung:	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.
