The clean mill is cooled to about 25°C and the nip is adjusted to about 3 mm. The polymer is added to the mill for banding. Ordinarily, the fluoroelastomer bands on the fast roll, but may be forced to the slow roll by increasing the temperature slightly on the slow roll. The nip is adjusted to about 5 mm to get a rolling bank in the nip.

Peeling of the roll is a mill feature. Bruise or mechanical marking are local indentations on the roll barrel combined with heatinduced bruises, firecracks and pressure cracks within or outside the rolling width. These marks are predominantly seen on the work rolls from the rear finishing stands of the rolling mills.
