<p>Roll of paperband usable in paper web cutting and turn-up systems or in baling includes an elongate multi-ply board having a center portion and side portions, each having an inside and outside edge portions and the inside edge portion being defined by a longitudinal first groove. Each side portion is folded to dispose same in contact with center portion. The paperband includes upper and lower transverse undulations to enable the board to be formed into a roll of paperband without materially affecting its tensile strength. The side edge portions may be located closely adjacent each other without any overlap therebetween so that a longitudinal line of weakness is formed therebetween or may overlap and render weakened edge portions. An adhesive coats the outer surface thereof when the paperband is used for baling.</p> |
