Abstract

The doctor roll has a rotating roll (14) in a roll bed (12), both of which extend transversely across the width of the machine. A device (20) bears against the back of the roll bed in order to press the roll against a coating roller (8) or directly against the web of prod. as it passes over a support roll. The doctor roll and the roll bed form part of a modular system such that the roll can be exchanged with another of different dia., and the roll bed can be correspondingly exchanged for another so that the axes of rolls of different dia. take up the same position relative to the carrier beam (10).
