ABSTRACT:
An improved steam heated corrugating roller includes an inner heating steam chamber constructed with a longitudinal cone shape with the exit for condensates at the wider end. Conduits are connected through the wider ends to a ring shaped housing. A ring is placed in the housing and includes several independent sectors which allow for radial movement between two positions vis a vis the bottom of the housing. This allows the conduits to remain open when the roller is spinning and closed when it is not spinning.
