Abstract (en)
[origin: EP0412305A2] What is provided is an apparatus for controlling the thickness of a material web passing through a nip, in which the diameter of at least one of the rollers (5) limiting the nip is variable as a function of temperature. At the same time, a flexible use of the apparatus is to be possible by a simple means. For this, there is an irradiating device (6) which irradiates the roller (5) on part of its circumference with infrared radiation. <IMAGE>
