Knifeholder Safety
IMPORTANT!
§Read and understand all instructions before operating the knifeholder. Failure
to follow instructions may cause the knifeholder to function incorrectly and
cause serious injury.
§The Tidland Series 'C' Knifeholder is intended to be used to produce a slit
when operated with a driven anvil system, and there is no other intended
purpose.
§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.
§Keep fingers clear of the blade edge at all times.
Receiving and Unpacking
§Handle and unpack the equipment carefully. Upon arrival, check the shipment
against the packing list.
§Any damage should be reported to the carrier at once.
§Equipment that will not be installed immediately should be stored in a clean,
dry location.
§Be careful to prevent moisture, dust, and dirt from accumulating in storage
and installation areas.
Sharp knives may cause
severe bodily injury.
Keep clear. Do not put hands in
machines. Keep hands away from
knife blades at all times.
Compliance with Federal, State, and
Local safety regulations is your
responsibility. Be familiar with them
and always work safely.

C. Mount Guidebar
1. Mark the mounting bolt center line on the support beam.
2. The guidebar must be straight within 0.010" (0.25mm) on a rigid and
vibration free support.
3. Measure the center to center distances between the mounting bolt
holes (A) on the guidebar and the overall length of the guidebar (B).
Note: Leave enough free space on each end of the support beam
for knifeholder removal.
Minimum Space Recommended
for Removal (Free Space)
Class I-25 2" (50.80mm)
Class I-33 2" (50.80mm)
Class II 3" (76.20mm)
Class III 4" (101.60mm)
4. Transfer the dimensions(A) on the support beam centerline.See note
in step 2; all mounting holes may not be equally spaced.
5. Center punch the mounting bolt pattern on the marked line.
6. Drill and tap the support beam for the mounting bolts.
7. Clamp the guidebar in place on the support beam.
8. Work from one end to the other installing the bolts until the guidebar is
securely fastened to the support beam.
Note: Make sure that the guidebar is aligned (parallel) with the
driven anvil.

D. Mount Knifeholder to Guidebar
1. Turn the manual position lock knob counterclockwise to fully retract.
2. Make sure that the auto-lock brake shoe is fully retracted into the
locking gib.
3. Align the dovetail mount and pinion gear to the guidebar and gear rack.
4. Slide the knifeholder onto the guidebar from one end.
5. Turn the traverse knob to make sure that the knifeholder moves freely
on the guidebar.
6. Adjust the pinion gear clearance using the traverse setscrew. Keep in
mind that the gib brake will "pull" the pinion gear into the gear rack, so
leave enough clearance.
7. Tighten the manual position lock knob to secure the knifeholder in
position.
Note: Where end installation is not possible by sliding the knifeholder
onto the guidebar, the knifeholder can be mounted by removing
the locking gib.
a. Remove locking gib mounting screws located on the front of
the control body.
b. Remove locking gib.
c. Place knifeholder on guidebar.
d. Reinstall the locking gib without altering the setscrew setting.
e. Hold the knifeholder firmly against the locking gib while
alternately tightening the locking gib mounting screws.

Note:
If the knifeholder does not move freely on the guidebar, refer to step 1.
Impact to the knifeholder body should never be used to move the knifeholder.

E. Install Pneumatic System
§Tidland Corporation recommends the use of a pneumatic system to prevent
airborne oil or water from contaminating the knifeholders.
The pneumatic system (Part Number: 520984) includes:
§Recommended operating air pressure: 60-75 psi (4.1-5.2 bar).
This is a guideline for knifeholder setup; the actual air pressure is dependent
upon application and material.
§Clean, non-lubricated, dry air is required for optimum performance of the
Series 'C' Knifeholder.
§Before operating the knifeholder, make sure that the air lines from the air
manifold to the blade cartridge are securely connected.
