摘要

The upper roller has a metallic roller body (2) and roller cover is wounded on the roller body. The roller cover has a heat conductivity increased opposite to a sleeve-shaped nitrile butadiene rubber roller cover (NBR) drawn up to the roller body. The roller body has elevations and slots at its outer circumference, against which the roller cover rests on inner peripheral side.
