Abstract

See full text

The sealing roll includes a stationary internal shaft and an inductively heatable roll jacket supported with freedom to rotate around the shaft. A plurality of induction coils is wound around the shaft over ferrites, which are open to the outside. Cables for the induction coils are laid through a cable conduit in the shaft for connection to an external induction generator. A water cooling channel for indirectly cooling the induction coils is also arranged in the shaft. A cavity is formed in at least an axial subsection of the sealing roll between the roll jacket and the shaft, and at least part of a temperature detection device is arranged in the cavity or adjacent to the cavity so that an IR temperature sensor receives radiation emitted by the roll jacket and thus detects a temperature of the roll jacket.
