5.3. Terminal Strip Feed Adjustment

Mechanical Feed Applicator

NOTE

When adjusting a mechanical feed applicator, always start by properly adjusting the stroke length. Then adjust the fine feed

adjustment to locate the terminal over the anvil.

1. With the terminal strip properly loaded, check the position of the lead terminal over the anvil. Locate

the feed pawl in the desired feed pilot hole of the carrier strip. Actuate the applicator to move the feed

pawl forward. The lead terminal must be centered over the anvil.

2. Watch the feed pawl as the machine is hand-cycled (or slowly cycled) several times. It should have

enough over-travel on the backstroke to pick up the next terminal, but not so much over-travel that the

feed pawl passes completely over the feed hole.

NOTE

At the end of its backstroke, the feed pawl should be at the back edge of the feed hole to be used. The backstroke must not be

longer than this; otherwise, the feed pawl might not drop into the feed hole.

If the forward limit and backstroke setting are correct, the feed adjustments are complete. If not, continue

with the next step.

NOTE

There are two adjustments that work in combination to properly position the lead terminal over the anvil and give the proper

backstroke position to pick up the next terminal feed hole. Use one or both adjustment types to properly adjust the applicator.

3. If the lead terminal is not centered on the anvil, make note of the position and continue to cycle the

applicator to check the backstroke position.

NOTE

At the end of its backstroke, the feed pawl should be at the back edge of the feed hole to be used. The back-strike must not be

longer than this; otherwise, the feed pawl might not drop into the feed hole.

If the lead terminal is not centered over the anvil and the backstroke position is incorrect, both the stroke

length and the fine feed position must be adjusted. Stroke length (backstroke position) must be adjusted

before final centering of the terminal over the anvil. Continue with the next step.

4. Loosen the lock screw, stroke length adjustment. See Figure 6.

5. Turn the stroke length adjustment screw counterclockwise to reduce the stroke length or clockwise to

increase the stroke length.

6. Tighten the stroke length adjustment lock screw.

7. Repeat steps 1 through 6 as required until the proper stroke length is achieved. The terminal might not

be centered over the anvil; this will be adjusted at a later step.

If the feed pawl stroke length is satisfactory, and the backstroke position is correct, but the lead terminal is

not centered over the anvil, the stroke is correct; however, the position is incorrect. In this case, an

adjustment to the fine feed screw is required. Continue with the next step.

8. Adjust the feed pawl position as follows:

a. Loosen the fine feed adjust lock screw on the side of the feed pawl holder to allow the fine feed

adjustment screw to turn. Refer to Figure 6.

NOTE

Do not remove the fine feed adjust lock screw. A nylon plug is captured behind the lock screw. Loss of this plug will cause

damage to the fine feed adjustment screw threads when the lock screw is tightened.

b. Turn the adjustment screw counterclockwise to move the feed pawl away from the anvil and

clockwise to move the feed pawl toward the anvil. Center the terminal over the anvil.

c. Tighten the lock screw to secure the fine feed adjustment screw.

9. Re-check the adjustment for the proper position and stroke as described in step 1. Repeat the

adjustment procedure as necessary.
