of production time by switching to Fernite knives.

Benefits of using Fernite knives
Knives which deliver significant benefitsA small change for long-term gain.
Knives are a small, simple part of the wallboard
production process.
But they are also one of the most crucial.
Underperforming, short-life or blunt knives can cause
bottlenecks, machine downtime and wastage due to
board damage.
Fernite knives have been carefully developed to solve
these problems.
Combining long knife life with exact tooth pitch,
Fernite knives can deliver significant year one savings
in maintenance time alone.
Additional long-term savings are made due to scrap
reduction, longer production runs and improved
productivity.

Tooth pitch selection - Fernite recommendation
We offer a wide range of knife options to ensure optimum cuttingperformance and efficiency.
To optimise the performance of the knife and ensure the most accurate cut on the board, the table below is a guide to
selecting the right tooth pitch, depending on the board thickness:
We are happy to provide guidance as to which tooth profile would best suit your operations. For technical enquiries please

Choice of knife thicknessWe offer a choice of thicknesses, supplying both industry
standards, 0.032” and 0.048” (0.81mm and 1.2mm).

Additives and board linings are commonly used to modify traditional wallboard.
Using these additives can result in increased wear, or the build-up of material on the teeth and faces of the knife which can
impact on the knife’s cutting performance.
Our range of coated knives have been developed to
reduce the build-up of material at the root of the teeth.
We offer three coating types:
Non-Stick
Superior
Our standard non-stick coatingto reduce material pickup onthe knife.
Premium

Material SpecificationWe only use high quality stainless steel for the manufacture of
wallboard knives. This ensures adequate protection from
corrosive salts present in the gypsum slurry.

Our knives achieve optimum performance when
mounted with the plain side facing the in-feed end of
the conveyor.
The tips are then in the same vertical plane at mid-
point of cut, ensuring a clean cut.
With uniform, precise tooth pitch and straightness,
Fernite knives can be easily mounted without the
need for careful pairing and checking.
For optimum cutting performance we recommend:
● The linear speed of the knife should be
marginally faster than the speed of the
conveyor- ensuring the points exit from the cut
cleanly, and ahead of the following board.
● When in cutting mode (as opposed to
perforating) the knives are mounted with a
maximum of 1mm clearance point to root at
mid-point of cut.
● For optimum performance the root of the tooth
should not pass through the paper - a 1mm
clearance is recommended. This avoids build-
up of material in the roots of the teeth.
