Adjusting Die Plates on Mechanical Time Clocks
New die plates on mechanical time clocks must be adjusted to ensure clear, centered print impressions.
Proper spacing prevents light prints, smearing, and uneven punch marks.
Die plate adjustment is a precision process that balances pressure across the print wheels.
Basic Die Plate Adjustment Procedure
| Step |
Action |
| 1 |
Back plate screws out two turns |
| 2 |
Cut narrow strip of paper |
| 3 |
Fold and slide behind plate between screws |
| 4 |
Avoid contact with print wheels |
| 5 |
Tighten screws and test print |
Fine-Tuning Print Quality
| Adjustment |
Result |
| Add paper shims |
Increases pressure |
| Remove paper shims |
Reduces pressure |
| Shift left or right |
Centers print |
Multiple test prints may be required. Small changes create noticeable differences in print clarity.
Why Adjustment Is Necessary
- Manufacturing tolerances vary
- Clock mechanisms wear differently
- Paper thickness affects pressure
Die plate alignment is both mechanical precision and practical tuning. Once set correctly, print quality remains stable for long periods.
FAQ
Do new die plates ever work without adjustment?
Rarely. Nearly all installations require spacing correction for optimal print quality.
Can improper adjustment damage the clock?
Yes. Excess pressure can wear print wheels and plates prematurely.
