Adjustment Procedures
1. Adjust the length of engagement of knuckle joint
attached to loop clamp lever
cylinder to 4 to 4.5 mm.
2. Move the open/close cylinder to and fro and adjust so that
the distance from the top surface of loop clamp base plate
to the opening of loop clamp lever
mm.
3. Supply air to the machine.
4. Press No. 6 button of the solenoid valve on the device
side and make sure that the top end of the loop clamp
lever comes in contact with the loop clamp base plate.
1. Loosen the fixing screw in clamp feed base plate and adjust
the position to the specified dimension.

Results of Improper Adjustment
If the opening of the loop clamp
lever is excessively wide, it may
interfere with the belt loop click.
When the opening is closed, the
loop clamp lever does not engage
with the loop clamp base plate. As
a result, the loop may not be able
to be held.
○ If the position is improper, the
belt loop may not be able to be
securely clamped or the clamp
feed base plate may interfere
with the belt receiver unit.
○ If the parallelism is not obtained,
the belt loop is not at right angles
with the fork resulting in the dog
ear.
