Abstract

Apparatus and processes for producing paper roll products with spaced core sections. A core substrate is arranged on a mandrel, and then divided into a plurality of core sections. The core sections are then separated from each other on the mandrel to form gaps between the core sections. Paper web material can then be wound onto the separated core sections to form a log of rolls. The log is then cut into final paper roll products.
