Bottle Labeler Jams After a Format Change

Verify the complete format setup—guides, feed screw, starwheels, centering bells, bottle plates, applicator height and saved recipe. Mixed parts or one skipped reference point can create a jam downstream.

Lock out the machine before reaching into cutters, feed screws, starwheels, vacuum drums, driven rollers or hot-melt systems. Follow adhesive and shrink-tunnel burn precautions.

Locate the fault

• Bottles contact the infeed screw or starwheel
• Labels crease where containers rotate
• Jams begin only with the new bottle
• The labeler runs in manual mode but not at production speed

Inspection sequence

1. Compare installed parts with the signed format bill of materials
2. Slow-cycle an approved empty bottle through every transfer under the manufacturer procedure
3. Verify all mechanical reference scales and applicator height
4. Confirm recipe name, revision and critical position values
5. Measure representative production bottles against the approved sample
6. Increase speed gradually while noting the first loss of control

Corrective work

• Install the complete correct format kit
• Reset height, guides and centering with the specified gauges
• Load and verify the controlled recipe
• Correct bottle-quality variation or formally qualify a revised format setup

Operating records and follow-up

• Store format kits as complete sets
• Use a two-person changeover verification for critical points
• Keep master bottles
• Lock recipes by access level
• Record the first jam point instead of only clearing the pile-up
