Seamed
Press Fabric
Safety with Seam
Safety is the number one driver for seamed press fabrics
Seamed felts have a significant participation in the Kraft paper
segment, P&W and Pulp, for both American market and South
America market
This has motivated and challenged us to the development a felt
for Tissue machines
Including Crescent Former - 2009

Hurdles to Developing a
Seamed Press Fabric
for Tissue Applications
5
Development Goals
Drying equivalent or better than our
best endless tissue technology
No sheet breaks at the seam
Runnability equal to or better than
our best endless tissue technology
No seam mark in the sheet
Quick and easy installation
6
Improved Base Fabric Pressure Uniformity
We began with a finer and
more uniform base fabric
design to provide the best
possible sheet dryness on
tissue and towel grades
This was a technological
leap in base fabric
uniformity

New Tissue Seam TechnologyPrevious Seam Technology
31 kg/cm pressure and 3 kN/m MD Tension
7
Loop Size
Consistently manufacture
quality loops 20-30% smaller
than anything we have made
before
Reductions to both the height
of the loop and the length of
the loop

Tissue Seamed Press Fabric Milestones
2009
Tissue Customer Challenges us
to develop a successful seamed
press fabric for Crescent Former
machines
Trials are started on Pilot Machine
making 16 gsm tissue in Crescent
Former configuration. One trial
produced NO SEAM MARK
November 2009
First successful run on
Crescent Former
July 2013
