Aligner Station Timing Check; Hopper - IBM 1402 Reference Manual

6. Check that each card is free at 353
0
and gripped
tight at 357
0
(Figure 3-57).
SECOND INTERMITTENT ROLL
The second, stepped feed roll must be in proper time
before the second, intermittent feed-- roll is timed.
For a timing check, refer to Feed Roll Timing Check,
First and Second Intermittent RoGs, steps 5 through
7.
NOTE:
The second, intermittent feed roll can be timed
with the· punch unit in the machine; however, it is
easier when the punch unit is removed.
1. Trip clutch and turn machine to 290
0
•
2. Insert cards lengthwise between each roll of the
second intermittent feed roll.
3. Turn machine backwards to 286 0
•
4. Adjust eccentrics (only if necessary) at each end
of second intermittent feed roll shaft so that each
card experiences a slight drag. Keep punch marks
on eccentrics facing punch marks on intermittent
feed-roll opening arms (Figure 3-58).
5. Check to see that each card is free at 290 0 and
gripped tight at 284
0
(Figure 3-57).
Aligner Station Timing Check
To check these timings, the punch unit must be re-
moved. The first stepped feed roll must be in time
before the aligners are checked.
1. Place die card-guide (Figure 3-59) in die position
(Figure 3-55 ) .
Figure 3-59. Die Card Guide
2. Place timing-mark gage over the die card-guide
(Figure 3-55).
3. Place cards in the hopper; trip clutch and feed
cards manually for two card cycles.
4. Continue turning machine and check that a card
finishes forward aligning to within .005" of the
forward aligne' r timing mark on the gage before
351 0 (Figure 3-60). The trailing edge of the card
must travel at least 1/32 inch past the feeding
Figure 3-60. Timing Mark Gage
edge of the forward aligners prior to the forward
movement of the forward aligners.
5. Check for .005"-.015" gap between card and fixed
side-aligner block (Figure 3-55) under the follow-
ing conditions:
a. The card must be fed while being ' held
against the left, side plate of hopper.
b. The check must be made prior to side align-
ment.
6. Feed cards held against the right, side plate of
hopper.
a. Check the right-side-aligner surface for .005"
minimum clearance to the edge of card.
b. The check must be made prior to side align-
ment.
FORWARD AND SIDE ALIGNER ADJUSTMENTS
Before performing these adjustments, be sure the first
stepped roll is in time. Refer to Timing Check, First
Stepped Feed Roll and First Intermittent Feed Roll.
Also, to basically get the forward and side aligners
in time, refer to Timing Checks, Forward and Side
Aligners.
1.
Trip clutch and turn machine to 351 0
•
2. Adjust forward aligners so that the trailing edge
of the card is against each aligning surface of the
forward aligners, and that the leading edge is
within .005" of the forward aligner timing mark
on the timing-mark gage at 351 0 (Figure 3-60).
Turn the adjusting screw of the forward aligner
clockwise in order to move the forward aligner
away from the hopper. Turn the adjusting screw
counter-clockwise to move. the forward aligner
toward the hopper (Figut. e 3-61).
3. Check the forward aligner setting by manually
feeding cards through the machine. Check that
the leading edge of the card is within .005" of
the forward-aligner timing marks at 351 0
•
The
trailing edge of the card must travel at least 1/32
