ABSTRACT:
A method for crimping paper roll wrap overhang is provided. The method comprises (a) forcing a portion of the wrap overhang towards the longitudinal axis for generating a fold in the wrap overhang, and (b) creasing the fold against the end face with a creasing member moving in a tangential arc over the end face. The method is particularly suitable for crimping roll wrap overhangs of over 6 inches and for providing more regular crimps by reducing bunching of the wrap.
