3.7.7 Pinch Wheel Setup
3.7.7.1 Pinch Wheel End Block Installation and/or Removal
The pinch wheel end block (Figure 3-47) must be installed at end of the rail (machine front side) for both
input and output buffer lanes. The purpose is to guide the position of the pinch wheel on the LM (linear
motion) rail between first lane and last lane.
Figure 3-47 Pinch Wheel End Block
To install the pinch wheel end block on LM rail:
1. Remove circlip (A).
2. Loosen all screws (B) and remove the shaft stopper block (C) from pinch wheel plate (D).
3. Insert the pinch wheel end block (E) into LM guide rail (F).

NOTE Do not remove the bearing stopper (G) to prevent the bearing from dropping out
(Figure 3-49).

4. Place the end block vertically (end block at the bottom surface (Figure 3-50).
5. Slide in LM guide (H) carefully and remove the bearing stopper (G).
Figure 3-50 Inserting the LM Guide
6. Install shaft stopper block (C) and tighten all screws (B) to assemble with the pinch wheel
plate (D).
7. Install circlip (A).
8. To remove pinch wheel end block from the LM guide rail, reverse all the steps above.
This setting is applicable for both input and output buffer lanes.

3.7.7.2 Pinch Wheel Gap Adjustment
To verify that the pinch wheel is exerting sufficient pressing force, manually insert a strip and verify that
the strip cannot easily move forward when held back by hand while the pinch wheel rollers are engaged
and in rotation.
Figure 3-51 Inserting a Strip
The gap between the pinch wheel should be adjusted so that the strip is not fully pressed down by the top
roller onto the bottom roller. If the adjustment is done correctly, the top roller will slip or rotate freely if
there is no obstruction to move the strip out to the buffer lane.
To fine-tune the strip in/out gap on pinch wheel (Figure 3-52):
1. Tighten screw (A) to determine pinch wheel contact with LM guide rail.
2. Tighten screw (B).
3. Adjust screw (C) to define the strip in/out gap.
4. Adjust screw (D) to increase or decrease the gap in between top roller and bottom roller,
until all strips are able to move forward or backward by hand with minimum force when the
wheels are engaged.
