Abstract
A coupling device for the supply and discharge of a heating medium in combination with a godet having a twin roll jacket and guide means provided within the jacket for directing the flow of a heating medium necessary for heating the godet. The device has a hollow shaft arrangement secured to the godet, and the shaft arrangement includes an outer pipe spaced from an inner pipe to define an annular space therebetween for supplying the heating medium to the godet and a passage for removing the heating medium from the godet. The outer pipe and the inner pipe each are permanently connected at one end to the godet for rotation therewith and a rotary pressure cap is disposed at a free end of said hollow shaft arrangement.The rotary pressure cap has means for engaging the other ends of the pipes so that the pipes are allowed to rotate within the rotary pressure cap and the engaging means also allows the outer pipe to expand longitudinally due to temperature fluctuation and to cause movement of the rotary pressure cap relative to the godet.
