KNIFEHOLDER SAFETY
Important!
The Tidland Performance Series Knifeholder intended use is to produce a slit with an anvil system.
There is no other intended purpose.
Read and understand all instructions before operating the knifeholder. Failure to follow instructions
may cause the knifeholder to function incorrectly and can cause serious injury.
The knifeholder contains spring-loaded components. While operating the knifeholder, follow all existing
plant safety instructions and/or requirements.
Always wear stainless steel protective gloves when changing or removing the knife blade.
Sharp knives can cause serious injury. Do not put hands in machines. Compliance with federal, state,
and local safety regulations is your responsibility. Be familiar with them and always work safely.
Receiving and Unpacking
Handle and unpack the equipment carefully. Upon arrival, check shipment against the packing list.
Promptly report to the carrier any damaged equipment.
Equipment that will not be installed immediately should be stored in a clean, dry location.
Be careful to prevent moisture.

OVERVIEW
Tidland Performance Series Crush Knifeholder
Models WOR and WR
Class I and II Performance Series Crush Knifeholders WOR
(without regulator and gauge) and WR (with regulator and
gauge) are equipped with features that allow for improved control
of individual knifeholder operation and performance.
WR and WOR models are both equipped with an actuator switch
that extends and retracts blade cartridges independently of one
another without turning off the supplied air pressure to the
knifeholders.
Model WOR knifeholders function at the supplied air pressure
without individual down force controls. For best crush
performance results, Tidland recommends the use of individual
air pressure regulators for each knifeholder.
Model WR features a self-contained pressure regulator and air
gauge that allows the operator to control the down force for
individual knifeholders. Individual air pressure control at each
knifeholder counterbalances variations in blade radii and blade
condition, allowing for more consistent slit quality across the
web.
Crush Slitting
•Score slitting, often referred to as "crush" slitting in
international markets, is a common method employed in web
separation and is normally configured for a wrap-slitting
mode instead of a tangent web path.
•Crush slitting requires the anvil roll hardness to exceed the
knife blade hardness by 4 to 6 Rc points. An anvil roll at
Rockwell 64c is usually considered minimum.
•When configuring crush slitters, it is important that the
centerline through the knife blade be placed slightly
downstream of the centerline through the anvil roll and
parallel to blade cartridge travel. This prevents lateral blade
tracking. The goal is to have a slight castering effect. The
actual offset is not critical; a reasonable offset is between
1/16" to 1/8".
•Tidland-Camas offers design assistance regarding your
Crush Slitting System requirements. (1-800-426-1000)

ORIENTATION
Crush Slitting Blade Profiles
•These blade profiles should be viewed as reference points in determining the optimum profile for
any given material.
•Smaller tip radii and acute angles result in rapid tip fracture and anvil roll grooving.
•Larger tip radii and included angles require more force to slit.
•To reduce chipping and rapid dulling of blades, it is important to remove burred edges from
resharpened blades.
•Make sure to grind the blade edge smooth to avoid dust formation during the slitting process.
•See also: Knifeholder Supply Pressure vs. Down Force Chart on page 19.

ORIENTATION
Air Supply System
Tidland Corporation recommends:
•the use of a filtered and regulated pneumatic system to prevent airborne oil or water from
contaminating the knifeholders. Clean, non-lubricated, dry air is required for optimal performance
of the knifeholder.
•the use of individual regulators for each knifeholder for improved blade life and cut quality
performance.
Individual air pressure settings will depend on blade conditions and web material.
Note: The WOR Model with pneumatic mount knifeholder requires two manifolds.
•One supplies the pneumatic mount;
•The other supplies each knifeholder independently for variable air pressure regulation.
(See Air Hose Fitting Chart on page 11.)
Part No. 520984 air filter system components include:
A - Quick exhaust valve with muffler
B - 3-way manual valve with muffler
C - Coalescing filter
D - 5 micron air filter / pressure regulator with gauge
E - 3/8 (9.52mm) supply air lines
Model WOR with pneumatic mount requires two filter systems.
