knifeholder and providing side stroke.
– Use when positioning the knifeholder blade to the
anvil ring blade only when product machinery is not in
operation.
– Using the actuator switch with the setup button will
extend the knifeholder and provide half the side stroke
distance.
To position the knifeholder, see pages 18-19.
Switch UP (Retract)
– Reverses (returns) the blade cartridge side stroke
and then fully retracts the blade cartridge.
– Retract when:
the knifeholder is not in operation.
adjusting blade overlap with depth control knob.
traversing the knifeholder to slit positions.
Switch DOWN (Extend)
– Used with setup button, extends the blade cartridge
and then swings it at half side stroke.
– During operation, extends the blade cartridge and
then swings it at full side stroke.

KNIFEHOLDER BLADE GUARD OPTIONS
This guard does not protect against bodily injury during handling and transport.
call Maxcess Customer Service.
Pneumatic 360° Blade Guard Cartridge
Class II – 548274
Class III – 548275
Shown in the unguarded (1) and guarded (2) positions.
For information about the mechanical
360° Blade Guard Cartridge,
Extending the Blade Guard
The blade guard is actuated automatically via an internal air circuit interface between the knifeholder
and the cartridge.
The cartridge extends and the blade guard retracts as the supply air is distributed at the setup knob in
either the GREEN (RUN) or YELLOW (SETUP) positions.
When the supply air is turned off at the setup knob RED (RETRACT) position, or at a gang manifold shut
off valve, the cartridge retracts and the blade guard extends out of the cartridge.
Flow Control Valve
The flow control valve assembly (3) provides a time delay between cartridge retraction and the blade
guard extension. Increase the delay by turning the flow control knob clockwise.

Select Slitting Type
TANGENT
WRAP
Knifeholder axis should be 90° to web path.
Tangent slitting requires knifeholder setback.
Knifeholder axis should bisect the wrap angle.
Knifeholder setback is not required.
For best slit result, the web must be in contact with the anvil knife ring at the cut point. If the web
contacts the top blade ahead of the cut point, the material will tear instead of slitting cleanly.
Geometry shown is based on medium weight kraft paper. For assistance with other web materials,
call Tidland Customer Service, 1-800-426-1000.

Easy Glider (Linear Bearing)
Manual or Pneumatic Lock
READ FIRST
Do not remove the factory-installed short rail
section from the linear rail.
This rail section must be used to install the
knifeholder onto the guide bar rail.
Failure to use this rail section when installing the
knifeholder may result in bearing damage and
void bearing warranty.
Mounted linear bearing is factory preset to be
loose in the knifeholder back plate.
Do not attempt to tighten or adjust. The
movement of the bearing allows the knifeholder
to float freely when traversing. When the
knifeholder is locked to the guidebar the bearing
movement will cease.
Mount Knifeholder
1. Choose at which the end of the guide bar the knifeholders will be mounted.
Locate and remove the #10-32 UNF screw from the end stop on the face of your guide bar.
2. Do not remove the short rail from the knifeholder bearing.
3. Unlock the knifeholder brake.
Manual Lock: turn brake knob counterclockwise.
Pneumatic Lock: pull up on traverse knob.
(Push the brake shoe up into the back plate if
protruding out.)
4. Install the knifeholder:
a. Hold the knifeholder and short rail
section together. Carefully place the rail
section into the keyway on the guide bar.
b. Align the short rail section with the fixed
bearing rail on the guide bar.
c. Slide the knifeholder onto the fixed
bearing rail.
5. Remove short section of bearing rail from the guide
bar; keep it for future knifeholder removal and
maintenance.
6. Repeat Steps 4a-4c until all knifeholders are
installed on the guide bar.
7. After all knifeholders are installed, reinstall the
#10-32 UNF socket head cap screws in the end stop
on the guide bar.
8. Reinstall blade cartridges on knifeholders (p. 23).
9. Toggle the actuator switch up on all knifeholders
to retract blade cartridges.

Air manifolds and quick disconnect
fittings are also available from Tidland.
Recommended operating air pressure: 60-90 psi (4.1-6.2 bar)
This is a guideline for knifeholder setup. Actual air pressure is dependent upon application and
material.
Maximum operating air pressure: 100 psi (6.9 bar)
Clean, filtered, non-lubricated, dry air is required for optimal performance of the knifeholder.
Before operating, make sure that the air lines from the air manifold to the knifeholder are
securely connected.
Pneumatic System Requirements
To provide the correct air pressure and help achieve quality slitting, Tidland Corporation
recommends the use of a filtered and regulated pneumatic system that will prevent airborne oil
or water from contaminating the knifeholders.
The pneumatic system includes:
A) 3/8" (9.5 mm) supply air lines
B) 5 micron air filter/pressure regulator with gauge (0-100 psi or 0-6.9 bar)
C) Coalescing filter
D) 3-way manual valve with muffler
E) Quick exhaust valve with muffler

Blade Grinding and Finishing
Correct blade sharpness is essential for shear and crush slitting
operations.
To reduce chipping and rapid dulling of blades, it is important to remove
burred edges.
Grind the blade edge as smooth as possible to avoid dust formation
during the slitting process.
Before putting blade into operation, install the blade and set up the
knifeholder at the anvil ring. Manually rotate the blade against the anvil
in the reverse direction for a few revolutions. This will help deburr the
blade after grinding and provide a smooth slitting edge.

Manual Swing Cartridge – Class I
The Class I cartridge was redesigned in 2003 for improved durability. The previous design is no longer
available as a complete assembly.
To update the previous design to the current design, you will need to order four new parts to use
with your existing cartridge: dovetail block, blade guard, inboard strut and bearing housing. Use the
(Current) part number listed below.
To repair the previous design, use the (Previous) part number listed below. These parts are available
by special order only.
The two cartridge designs are interchangeable with the control body, if you prefer to order a complete
new cartridge assembly. When ordering, please locate the part number on your cartridge assembly
and have it ready when you call.
