3. Loosen hopper back plate and shift to obtain
.012" to .030" clearance between lower card guide
and hopper back plate guide.
4. Trailing edge of first lower card guide should be
flush to .015" below leading edge of second lower
card guide. See Figure 3-24.
5. Position first upper card guide for .012" to .030"
clearance to lower card guide. Adjust by loosen-
ing screws in mounting bar and shifting guide to
desired position.
6. Position second upper card guide for .012" to
.030" clearance to lower guide.
a. Loosen tie bai holding screws.
b. Make certain the tip of the forward aligner
is
belo~
the top surface of lower guide. Ad-
just by positioning the upper guide. (Aligners
travel in a slot in the upper guide.)
7. Position third upper card guide for .012" to .030"
clearance to lower guide by loosening mounting

Feed Rolls and Aligner
Statio~s
For machines that do not ~ve a lowering frame, refer
to Redesigned Punch Feed for feed roll and aligner
stations, checks, removals, and adjustments.
Timing of the first and second stepped feed rolls,
first and second intermittent feed rolls, and the card
aligners is checked by means of the following proce-
dures.
These procedures, however, are not final ad-
iustments.
The synchronous tooth is used for all of
these steps. See Figure 3-25.
. Danger: Be sure machine power is turned off before
these adjustments are made.
FIRST STEPPED AND FIRST INTERMITTENT FEED ROLLS
TIMING CHECK
1. Pivot hopper down.
2. Remove punch feed brushes, and PFR brushes or
card guide.
3. Trip clutch at 300°.
NOTE:
The following checks can be made either
with punch unit installed or removed.
4. With clutch engaged (315°) crank machine to
333°.
5. Insert a card lengthwise from hopper end so it is
between the rolls on one end of first stepped feed
roll ·shaft. Make sure first intermittent feed roll
does not interfere with card.
6. By turning feed backward, check that card is
free at 331 ° and is gripped tightly by first stepped
feed roll at 328°. This
~jndicates
first stepped roll
is in time.
7. Crank machme to 352°.
