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 in relation to the slug

blade. Locate the feed pawl in the desired position of the terminal (typically the end of the wire barrel).

Refer to Figure 6. The slug blade must remove the connecting tab between lead and second

terminals

—without deforming either terminal.

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 moves up onto the body of the terminal (see Figure 9).

NOTE

If the pick-up point is the mating end of the terminal, the backstroke over-travel should be about equal to the distance between

the wire barrel and the mating end of the terminal (see Figure 1). For other types of terminals (for example, ring tongue),

over-travel should be about the same, depending on the terminal features and configurations (for example, stud hole).

Figure 9

If the backstroke position is correct, the tab is correctly slugged out, and the terminals are not damaged,

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 slug blade does not shear the terminal in the correct position, make note of the position and

continue to cycle the applicator to check the backstroke position. If the lead terminal is not slugged out

correctly 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 other

terminals under the slug blade.

4. Loosen the stroke length adjustment lock screw (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 proper stroke length is achieved. The terminal might not be

slugged out correctly (or positioned under the slug blade correctly); this will be adjusted in a later step.

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

terminal is not slugged out correctly (or positioned under the slug blade correctly) and the stroke is

correct, but the position is incorrect, 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.
