Snugger Clamp
Setting
(Parallelism)
The adjustable snugger plate, rear rail guide and fixed snugger plate are all
interchangeable with similar units to facilitate differences in board thicknesses
(0.8mm, 1.0mm and 1.6mm).
The following checks and adjustment settings for the snugger clamp is applica-
ble to all three size configurations.
The procedure for setting up snugger parallelism is as follows:
1. Using a 0.10mm feeler gauge check that the gap between the fixed snugger
plate and transport belt guide is set between 0.10mm - 0.15mm. Ensure
that parallelism is achieved along the full length of the snugger plate.
2. If adjustment is necessary. Slacken fixed snugger plate securing screws (3
in number) and adjust.
3. Using a vernier gauge measure the distance between the fixed snugger
plate and rear rail guide, gently move the rear rail forward until a gap of
250mm ±0.1mm is achieved. Ensure that parallelism is maintained along
the full length.
4. If adjustment is necessary. Slacken rear rail guide securing screws (3 in
number) and adjust.
5. Ensure that parallelism is achieved along the rear rail guide and adjustable
snugger plate. This is achieved by using a vernier gauge and checking that
the rear rail guide/adjustable snugger plate is the same distance to the front
snugger plate. Adjust the two stop mount bolts to move the snugger plate
if required.

Snugger Clamp
Setting (Height)
The procedure for setting up the snugger height is as follows:
1. Before setting snugger height, check the rail to table height (Rising Table
Chapter).
2. Place a straight edge on the top surface of the rear rail guide (Position A1
on figure below refers). Using a depth gauge indicator measure the distance
from the top of the rising table to the top of the rear rail guide.
3. Carry out same operation at Position A2.
4. Check that the dimensions in Steps 2 and 3 are the same (to within 0.2mm).
If necessary adjust by slackening snugger support bracket securing screws.
Do not fully re-tighten screws at this point.
5. Carry out identical checks at other end of adjustable snugger plate (Position
B1 and B2). On completion of check/adjustments fully re-tighten bracket
securing screws.
NOTE
If adjustments are made ensure that a gap of 250mm is maintained as laid
out in Parallelism setting up.
6. On completion of setting up ensure that the board is free to move along the
transport rail without jamming.
7. Pneumatically operate the snugger clamp with a board fitted. Ensure that
the board is gripped evenly along its entire length.

Home Position Rail
Width Check
1. In Diagnostics, select Rail System and Select Module.
2. Select Home Rail Width and Run Diagnost.
3. Select Adjust and set board width to 250mm.
4. Select Drive Rail to Board Width.
5. Select Run Diagnost.
6. Check that the board clamp width is between 250.35mm - 250.55mm.
7. Check that the mid rail width is between 250.35mm - 250.65mm.
8. Check that the rail end green insert width is between 250.35mm -
250.85mm.
NOTE
If any of the rail widths are out of tolerance do not adjust the rails, adjust the
position of the rail home position sensor and recheck.
9. Using a suitable test board, with the rail width programmed to the board size,
select Cycle Board on Belts.
10.Select Run and ensure the board runs through the entire length of the rail
system for 10 complete cycles, without jamming or excessive clicking of the
board edges.
NOTE
If any jamming occurs investigate the position of the board/snugger clamps, mid
rails and the green inserts at the rail ends before repeating the check.
