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.
Claims8
An apparatus for forming paper roll products, comprising:
- a core slitter assembly having a plurality of slitter mechanisms, each slitter mechanism including a cutting disc and a gripper mechanism, and the slitter mechanisms are mounted to be moveable between a non-cutting position wherein the slitter mechanisms are away from a core substrate, a cutting position wherein the slitter mechanisms are positioned to cut the core substrate into a plurality of core sections, and a gripper engagement position wherein the gripper mechanisms engage the core sections, the plurality of slitter mechanisms are mounted to be moveable in a direction parallel to a longitudinal axis of the core substrate to space apart the core sections along the longitudinal axis.
