HEATABLE ROLLER

摘要

The roller (100) can be heated from inside the roller body (10) by a heater (20). Radially outside the heater (20) there are axially parallel drillings (30) evenly distributed over the periphery of the roller body (10) which are connected at the ends by annular chambers (31). The drillings (30) and the annular chambers (31) form a closed system which is partially filled with water. This system operates to make the temperature uniform via condensation heating in case of local temperature reduction.
