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 thickness, 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 thickness, and thereby the strength, of the thus formed core is sufficient for reeling and for the further handling of the roll.The invention also relates to a roll of a web of material, around which there is a wrapping composed of at least 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.

Abstract: The invention relates to an apparatus for spreading a fluid onto a moving web of material, especially for spreading size onto a paper web. It is previously known to spread fluid substances onto a moving web of material by means of a comb nozzle. Especially when size is being spread, the size tends to harden during stoppages, thereby clogging the openings of the comb nozzle. The apparatus according to the present invention enables a fluid to be spread onto a moving web of material without the apparatus getting clogged even in a dusty environment. By means of the apparatus it is possible to spread even rapidly drying fluids without the risk of the substance being spread drying in the nozzle opening or openings during stoppages.
