Escapement Gearing: Keep escapement gear train lubricated
on machines that use the drum-type friction clutch. Keep
card chips and other foreign matter out of escapement gears
and friction drive. Faulty escapement may be caused by
incorrect torque at the friction drive. All gear shafts
protruding through bearing support must be pulled to the
extreme forward position before tightening collars. Be sure
unsealed bearings are capped.
4.5 CARD FEED
4.5.1
Hopper
Adjustments
4.5.1.1 Magazine Springs
Form magazine springs to touch feed bed (1, Figure 4-3).
4.5.1.2 Feed Knives
Check card feed latch magnet adjustment. When card feed
latch magnet adjustment is correct, manually cycle the card
feed mechanism. With CF latch armature engaged with CF
cam follower arm, adjust both feed knives evenly to give
minimum clearance of 0.015 inch (0.040 inch maximum)
from feed knives to top edge of cards in hopper (2, Figure
4-3).
4.5.1.3 Throat
Adjust throat block (3, Figure 4-3) to place crown in direct
line with top edge of throat knife. Adjust throat knife (4,
- \
Figure 4-3)
for an opening of 0.008 to 0.010 inch. If
I
throat is properly adjusted, a 0.008-inch gage should freely
pass in three directions (Figure 4-3) but a 0.010-inch gage
should not.
4.5.1.4 Pusher Plate
I
The card-feed pusher-plate spring (5, Figure 4-3) is adjusted
to have 450-gram tension when one card is in the hopper.
4.5.2 Feed Clutch Adjustment
1. Adjust magnet yoke adjusting screws (Figure
44)
for
0.032-inch to 0.036-inch clearance between armature
and yoke at the operating end.
2. Form armature spring to exert tension of 100 to 120
grams in direction of A (Figure 4 4 ) and 230 to 250
grams in direction of B (Figure 44).
3. Position CF magnet unit to obtain 0.010-inch to
0.014-inch unlatching clearance between armature and
CF dog when armature is attracted (Figure 4-5).
