Abstract
A method of preparing an elongate web of sheet material for dividing into discrete stacks of web portions after reeling the web onto a drum is provided. The method includes forming transverse discontinuities in the web at spaced intervals corresponding to edges of the discrete stacks to be formed, the intervals progressively increasing along the web so that the discontinuities form angularly-aligned groups when reeled onto the drum.

A method of preparing an elongate web of sheet material for dividing into discrete stacks of web portions after reeling the web onto a drum, the method comprising
- forming transverse discontinuities in the web at spaced intervals corresponding to edges of the discrete stacks to be formed, the intervals progressively increasing along the web so that the discontinuities form angularly-aligned groups when reeled onto the drum.
A web processing system configured to prepare an elongate web of sheet material for dividing into discrete stacks of web portions after reeling the web onto a drum, the system comprising:
- discontinuity-forming equipment arranged to form transverse discontinuities in the web at progressively increasing intervals corresponding to edges of the stacks to be formed, so that the discontinuities form angularly-aligned groups when reeled onto the drum.
An elongate web of sheet material comprising transverse discontinuities at progressively increasing intervals, wherein each discontinuity comprises a transverse series of perforations.
