Choice weak point section equipped core null for core winding paper product

摘要

Disclosed is a core for core wound paper products, such as toilet tissue or paper towels. The core (20) is provided with a plurality of axially oriented continuous score lines (36), perforations, or holes. The continuous score lines (36), perforations, or holes weaken the core, so that upon flattening, vertices are formed. When the core (20) is rerounded, each score line (36), perforation, or hole forms a vertex, so that a predefined polygonally shaped cross section, more nearly approximating a circle, is formed.
