Abstract:
Method for the preparation of a paper reel (8) having a wound paper web for flying reel change by applying an adhesive tape (64) along an edge (83) of the web end, which has at least one outer tape having an outer adhesive surface for producing the joint between the web end and a paper web of a residual roll, and an inner tape which can be separated therefrom and has an inner adhesive surface for holding the web end on the next inner layer, by lifting of the outermost layer from the next inner layer, producing the edge (83) of the web end by cutting off an end section (82) from the outermost layer, applying the adhesive tape (64) and replacing the outermost layer on the next inner layer, a part of the outermost layer which is adjacent to the edge (83) of the web end being adhesively bonded to an adhesive strip of the outer adhesive surface while an edge strip adjacent thereto remains free and the inner adhesive surface adhesively bonds to the next inner layer, characterized in that, while the paper reel (8) remains otherwise unmoved, the lifting of the outermost layer is effected by placing a support surface, whose cross-section perpendicular to the axial direction of the paper reel (8) is substantially constant over its width, against the paper reel (8) and establishing a starting position in which a cutting line of the support surface, which cutting line is parallel to the axis of the paper reel (8), is in contact with a generating line of the paper reel (8), and the support surface is rolled, while the outermost layer is held resting on it, in the unwinding direction thereof on the paper reel (8), cutting off the end section (82) along the cutting line and applying the adhesive tape (64) to the next inner layer in such a way that the boundary between the adhesive strip and the edge strip coincides with the generating line, whereupon the support surface is rolled back to the starting position for replacement of the outermost layer.
