Octopus™ Stock Approach System
Octopus stock approach systems with dilution profiling ability allow the control of CD profile while paper machines are operating. A radial-type distributor, Octopus supplies a forming device (vats, hydraulic formers, or headboxes) with uniform flows across the width of the machine without the need for recirculation. Octopus stock approach systems are also flowrate insensitive. Internal diffusers reduce floc formation and an air bleed reduces entrained air. An air pad section reduces pulsation caused by fan pumps and pressure screens.
As basis weight supplied to each zone of the forming device is a function of flow and consistency, CD basis weight can be controlled by the Octopus stock approach system's ability to vary consistency in each supply zone. Consistency control of each zone is controlled off-machine, allowing operators to make profile corrections safely while the paper machine is in operation. Papermakers can expect reduced dry weight variation as well as a significant reduction of scrap due to profile variation.
