When you are satisfied with the width
between the jawplates, first tighten the
handles that clamp the pivot block
width adjustment with the jaws
parallel. Extend the synchronizer bar
and jaw cylinder for LH cases. Retract
the synchronizer bar and jaw cylinder
with the jaws parallel for RH cases.
Then remove the opened case from
the pins and pivot the jawplates so
that they are perpendicular to the
direction of carriage travel. If the
jawplates are not parallel to each
other while in their
HOME
position,
refer to Section 7.9.1:
‘Horizontal
Pinblock Adjustments’
.
If the synchronizer bar is not extended or retracted as far as possible, the jawplates will not be
parallel when they open during machine operation. Images of properly and improperly adjusted
synchronizer bars are shown below.
The images below demonstrate the effects of improper synchronization bar adjustments.
