Estimate Adhesive Pattern Timing
This calculator converts line motion into timing. That matters because adhesive application problems are often caused by timing that no longer matches actual conveyor speed or product spacing.
Instead of guessing at milliseconds directly, start with distance first, then convert it into time. That is usually the cleaner way to think about adhesive placement in real machines.
Gun ON Time = Bead Length ÷ Line Speed
Gun OFF Time = Non-Bead Distance ÷ Line Speed

If the timing looks right but the bead still looks wrong, the next step is troubleshooting process conditions and hardware.

How to use this calculator in real applications
On real equipment, timing values are often entered in milliseconds, but the underlying process problem is usually a distance problem. If line speed changes or product spacing changes, the old timing value may no longer place the bead correctly.
That is why it is often better to start with speed and distance first, then convert those into an expected timing window.
Common uses for this calculator
- Estimating initial gun on-time for a new adhesive pattern
- Checking whether a line speed increase changed bead location
- Reviewing off-time between product patterns
- Comparing placement timing across different product sizes
- Giving controls or maintenance a cleaner timing starting point
Common mistakes in timing setup
- Thinking only in milliseconds instead of distance and speed
- Changing temperature when the real issue is trigger timing
- Ignoring the gap between products
- Not checking whether line speed actually changed
- Assuming the gun response is instant with no delay
This calculator gives a timing starting point. Actual application timing may still need adjustment for trigger delay, pneumatic response, product tracking, sensor position, and real machine behavior.
