Another facet of this program is the development of a patient registry to track outcomes of women post-partum to help determine the true predictive values of NIPS
from different providers.
is modeled and displayed graphically in 3D so that machine operators can dial in their machines to get maximum results.
Dependent variables, which can be changed by the operator during the process: polymer melt temperature, die gap, draw ratio, nip
pressure, chill roll temperature, line speed, nip
This extremely uniform base construction gives better pressing uniformity at the press nip
, which improves water removal from the sheet and provides better sheet moisture profiles.
Air trapped between layers is another cause of telescoping, so it's important to maintain either nip
pressure or web tension high enough to keep air out.
A "pseudo nip
," located just before the upper nip
at the top of the tower, narrows the space between film layers without actually pinching them closed, and minimizes the amount of air escaping when edge-fold slitting below the nip
The PM4 press section will have a high speed, three nip
SymPress II press with a SymBelt extended nip
press in the third nip
Some, such as Kiefel, acquire a basic unit and add on their own nips

Typical pressures in a shoe press are up to for 1400 kN/m or 13000 pli, but since the pressure is spread over such a wide nip
, the force per unit area that the sheet sees is gentler than in a conventional roll press.
BUSKER: I joined TAPPI in 1969 and published my first paper, on extended nips
and wet pressing, in 1970.
Improved press felt designs and softer roll covers produced wider nips
with reduced peak pressures.
