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.

Abstract: A crimper and method for crimping roll wrap overhang are provided. The crimper comprises a rotatable support for mounting to a drive shaft, a folding member on the support for engaging and bending flexible material (such as paper roll wrap) to generate a fold upon rotation of the support about a support axis, and a crease roller on the support in direction of rotation behind the folding member for creasing the fold upon rotation of the support. The crimper and crimping method are particularly suitable for crimping roll wrap overhangs of over 6 inches. The present invention also provides a crimping assembly comprising the crimper described herein.
