<p>The invention relates to a separate roll flap means of preferably paper material having a particular method of folding and having areas (18, 20) of previously prepared glue strings (21, 22, 23) having according to the invention a particular given characterizing pattern, which is preferably protected by a protective film, this protective film being removed at the moment when the roll flap means is aligned and attached to the new paper roll. The method of folding offers an efficient and fast and precise alignment of the roll flap means onto a new web material roll for splicing of, e.g., a thin web of paper by means of a multi-arm web roll reel without any risk that the spliced paper web will be folded or broken upon feeding through, e.g., a printing unit. For the manufacturing of the separate roll flap means there is preferably utilized paper spill remains of changed almost empty web rolls, whereby the roll flap means automatically gets the correct width and thickness at the same time as the cost of material for the manufacturing will become almost negligible.</p> |
