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.
