Abstract

Es wird eine temperierbare Walze (1) mit einem Walzenkörper (2) und je einem Walzenzapfen (4, 5) an jedem axialen Ende des Walzenkörpers (2) angegeben, wobei ein Strömungspfad für ein Wärmeträgermedium durch die Walze (1) vorgesehen ist, der in einem ersten Abschnitt radial von innen nach außen, in einem zweiten Abschnitt axial durch den Walzenkörper radial unter dessen Umfangsfläche und in einem dritten Abschnitt radial von außen nach innen verläuft.It is a temperature-controlled roller (1) with a roller body (2) and one roll journal (4, 5) on each axial end of the roller body (2) indicated, wherein a Flow path for a heat transfer medium through the roller (1) is provided, which in a first section radially from the inside out, in a second section axially through the roller body radially below its peripheral surface and in a third section radially from runs outside inwards.

Man möchte das Wärmeträgermedium mit möglichst wenig Aufwand durch die Walze treiben.You want the heat transfer medium with as little as possible Exerting effort through the roller.

Hierzu ist vorgesehen, daß im Bereich des dritten Abschnitts eine Führungseinrichtung (17) angeordnet ist, die die lokale Geschwindigkeit des Wärmeträgermediums in Umlaufrichtung in jeder radialen Entfernung von der Walzenachse an die lokale Geschwindigkeit der Walze in Umlaufrichtung anpaßt.

Figure 00000001
For this purpose, it is provided that in the region of the third section, a guide means (17) is arranged, which adjusts the local speed of the heat transfer medium in the circumferential direction in each radial distance from the roll axis to the local speed of the roll in the circumferential direction.
