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.

Abstract: A method and an apparatus for collecting plates from two rows of plates travelling side-by-side on a moving conveyor comprising inverting plates sequentially in one row of plates and merging said two rows of plates by depositing a plate from one row onto a plate in the other row to form a single row of double plates each having an inverted plate, and assembling a single row of said double plates into stacks. The double plates are assembled into stacks preferably by shingling the double plates to assemble a plurality of overlapped double plates, stacking shingled double plates to form horizontal stacks, turning each horizontal stack onto a side or end of the stack to form a vertically-stacked bundle, and rocking the vertically-stacked bundle on the side or end to align the plates on the side or end, rotating the bundle vertically through 90.degree.
