1.1 Establishing through detailed analysis of any specific headbox
design, the optimum and correct headbox process settings for any
machine operator to follow.
We call them "PAPYRUS RELAXATION TABLES" Since the busy operator will be more relaxed in setting the headbox variables and
liberated from the agony of the hit and miss approach. Hence he
can devote his time more effectively to other areas of the machinery.
1.2 Calculating in a comprehensive matrix format the safe distance
for jet mixing behind rectifier rolls and perforated plates as a
function of flow rate, stock temperature and other specific
design criteria.
1.3 Calculating in an elaborate format the jet characteristics as a
function of different slice geometries for different jet speeds
and other settings and illustrate the results pictorially in
order to compare the actual operating conditions versus the
ideal.
1.4 Establishing through detailed analysis of any specific headbox/
approach piping systems the sources of streak development if
they are existing and their remedies.
1.5 Calculating the change in the slice bottom lip extension as a
function of incremental vertical slice opening movement and
incorporate the relationship in the headbox process settings.
1.6 Determining the limitation and the potential capacity of any
headbox/approach piping systems.
1.7 Determining if modification of the existing headbox/approach
piping system is required, based on NO OR MINIMUM CAPITAL
INVESTMENT.
1.8 Comparing the manufacturer's original design criteria with the
true requirements.
1.9 Supporting papermill management in a rebuild decision by
selecting the right headbox parameters for their specific
needs.
1.10 Calculating in a matrix format the required local slice profile
bar travel for a specific machine and product basis weights and
compare the results with the intended design criteria.
1.11 Calculating in a matrix format the weight of each ply for
multiply sheet machines.
1.12 Calculating in a matrix format the production rate as a function
of specific machine speed and basis weight ranges.
1.13 Calculating in a matrix format the relationship between
production rate, headbox consistency, and flow rate at six levels of first pass retention.
1.14 Calculating in a simplified matrix format the overall material
balance for fibers alone, fillers alone or combined total solids without the agony of measuring white water consistency and conducting the related cumbersome calculations.
1.15 Calculating the critical headbox consistency based on the
furnish constituents and compare the results with the operating
conditions.
1.16 Calculating the ideal trailing sheet weights in Converflo type
headboxes and compare the results with the existing condition
for eliminating pulsation problems.
