ABSTRACT:
An apparatus 10 is provided for supplying a high-velocity flow of temperature regulated air 5 to the calender roll 90 of a paper making machine. Ambient air 1 is received into the plenum chamber 20 and distributed therefrom through a longitudinally elongated conduit means 30 which has an inlet 32 opening directly into the plenum chamber 20 and an outlet opening 36 along the other end thereof and defining therebetween a flow passageway 34. The outlet opening 36 is adapted to direct the air flow passing through the flow passageway 34 along the calender roll 90 in counter direction to the rotation of the calender roll 90. A series of spiral wound heating element coils 40 are disposed within the conduit means 30 at longitudinally spaced intervals along the length thereof to heat the air to a desired temperature by selectively powering the heating element coils 40. A flow turbulator 50 is disposed within the center of each spiral wound heating coil 40 in the flow path therethrough whereby the air passing therethrough is directed into contact with the coils of the spiral wound heating coil 40 thereby increasing the efficiency of heat transfer from the heated coils to the air.
