PROJECT SUMMARY - CONVERSION OF INCLINED
WIRE OPEN HEADBOX TO HYDRAULIC HEADBOX
improve sheet formation control and increase production speeds,
Glens Falls Interweb, Inc. converted an existing inclined wire open
headbox to a hydraulic headbox.
The conversion involved the removal of the top structure of the
existing headbox and replacement with new side pond plates and articulating
roof section. The articulating roof section allows for control of
stock velocities through the forming zone. Digital readouts were
supplied to indicate heel and slice positioning.
Water box seals were added to the headbox to improve sheet edge
quality. The new upper section can be pivoted open to allow access
for internal cleaning and maintenance.
GFI provided installation supervision, start-up assistance, and
a follow up process review for the headbox conversion project.
