ROLL WITH ADJUSTABLE DEFLECTION AND ITS USE |
摘要 |
A roll for the thermal treatment of a web of material (4) in which the web of material (4) is cooled to a defined predetermined temperature in a gap (5) between the roll (1) and a counter-roll (2) is formed as a deflection controlled roll with a rotationally fixed carrier (8) and a rotatable roll jacket (10) which is supported relative to the latter with support elements (11). The roll jacket consists of a plurality of concentric zones, an inner soft zone (16) and a thin outer zone (17) with good thermal conductivity, for example of metal. The roll surface (22), is for example cooled with cooling gas nozzles which are regulated by a temperature sensor (20) so that the roll temperature in the gap (5) adopts a defined temperature value. A roll of this kind, is for example suitable for use in a calender for the smoothing of a paper web or also for the processing or manufacture of a plastic foil.
