摘要

A heatable or coolable roll 10, has a shell 1, which forms the operative periphery of the roll and a channel 8, defined adjacent the interior periphery of the shell 1, through which a heating or cooling medium flows axially. The direction of flow or heating or cooling medium is reversed by a valve arrangement so that the roll periphery can present a substantially uniform temperature profile. IMAGE
