Abstract

Es wird eine Heizwalzenanordnung (1) angegeben, insbesondere für einen Kalander, mit einer Walze (2) und einer Heizeinrichtung, die eine sich zumindest über eine Arbeitsbreite der Walze (2) erstreckende Induktoranordnung (3) aufweist.The invention relates to a heating roller arrangement (1), in particular for a calender, having a roller (2) and a heating device which has an inductor arrangement (3) extending over at least one working width of the roller (2).

Man möchte eine Heizwalzenanordnung mit ausreichender Heizleistung bereitstellen.It would like to provide a heating roller assembly with sufficient heating power.

Hierzu ist vorgesehen, dass in Umfangsrichtung der Walze (2) verteilt mindestens eine weitere Induktoranordnung (4-7) angeordnet ist und die Summe der von den Induktoranordnungen (3-7) erzeugbaren Heizleistung mindestens dem Leistungsbedarf der Walze (2) entspricht.

Figure imgaf001
For this purpose, it is provided that at least one further inductor arrangement (4-7) is arranged distributed in the circumferential direction of the roller (2) and the sum of the heating power that can be generated by the inductor arrangements (3-7) corresponds at least to the power requirement of the roller (2).
