Abstract The invention relates to a method and apparatus for reeling a web of material onto a core by glueing the leading end of the web of material to the core and by rotating the core until the roll is of the desired thick- ness, by cutting off the web of material and by attaching the trailing end of the cut-off web of material to the roll. The method uses a core base onto which so many layers of the web of material are glued that the thick- ness, and thereby the strength, of the thus formed core is sufficient for reeling and for the further handling of the roll. In the apparatus according to the invention, a web of material (2) coming from a slitting machine (4), a sheet cutter or an unreeling frame is reeled onto a core (10),the apparatus having members (9) supporting and rotating the roll (11). As seen in the travel direction of the web of material, in front of the members (9) supporting and rotating the roll (11), there are members (8) which extend across the web of material (2) and are aimed at least at that side of the web of material which in the roll (11) faces inwards, i.e. towards the core (10), for applying a fluid substance, such as glue, water, color and/or various additives to the web of material being reeled. The invention also relates to a roll of a web of material, around which there is a wrapping composed of two layers of the web of material, glued to each other, and to a method of forming such a wrapping during the reeling of the web of material.
