station rolls are shorter in length so
that they may be shimmed away from
the machine plates to locate the punch
closer to the bendline, thereby achiev
ing a tighter fit on the snap.
WARNING: The gauge setting should not be made
while the #1 station is shimmed away fr.om
its normal location and protruding beyond
the other roll stations.
The top #1 roll is

The bottom roll is not restrained by the
bolt and washer but is held in position by a
shoulder on the #1 roll and it should be al

if required,
should be placed behind the top roll only.
