1. An apparatus for forming paper roll products, comprising:
- a mandrel having a longitudinal axis; and
a slitter mechanism having a cutting disc and a gripper mechanism, the slitter mechanism mounted to be moveable between a non-cutting position wherein the cutting disc and gripper mechanism are away from the mandrel, and a cutting position wherein the cutting disc is positioned to cut a core substrate disposed on the mandrel into at least two core sections and the gripper mechanism is engaged on an outer surface of one of the core sections, and the gripper mechanism maintain engagement with the outer surface of the core section to longitudinally space apart the at least two core sections on the mandrel.

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.

11. 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. An apparatus for forming paper roll products, comprising:
-
a mandrel having a longitudinal axis; and
a core slitter assembly having a plurality of slitter mechanisms, each slitter mechanism including a cutting disc and a gripper mechanism, the cutting discs and gripper mechanisms being independently moveable relative to each other, the cutting discs moveable between a non-cutting position spaced apart from a core substrate positioned on the mandrel, a cutting position positioned to cut the core substrate into a plurality of core sections, and the gripper mechanisms moveable between a removed position spaced apart from the core substrate and a gripper engagement position in engagement with the core sections, the gripper mechanisms further moveable in a direction parallel to the longitudinal axis to space apart the core sections along the longitudinal axis. - View Dependent Claims (20)
