Abstract
A method of producing a coreless roll from a web of fiber-based material, comprising laying a leading end (2a) of a material web around a non-expandable winding-on axle (3) having a fixed diameter of at least 35 mm and rotating the axle so as to wind the web (2) onto the axle. A friction-reducing agent in the form of water is applied to the axle or to the first turn or turns of the material web, thereby to reduce friction between the web and the axle. The axle is withdrawn from the resultant roll after completion of the web winding-on process.
