Abstract

The invention relates to a spool for winding a fibrous web, the lateral surface of which is formed by a coated spool core. The aim of the invention is to improve the winding quality by the fact that the outer lateral surface is formed by a plurality of separate coatings which are arranged axially next to one another, of which at least two adjacent coatings are made of different materials.
