Problems on this page:

Labels misaligned or skewed Labels not dispensing or web break Poor adhesion or lifting edges

Labels misaligned or skewed

Hits OEE: Quality

Symptoms: Labels crooked or in the wrong position, wrinkles, rejects.

Container speed mismatch

Match belt and roller speed to the product; sync the applicator.

Worn application rollers or brushes

Replace worn rollers and pads; check pressure.

Trigger sensor position off

Re-position the product sensor and apply point.

Prevention: Speed sync checks, roller maintenance, sensor calibration.

Labels not dispensing or web break

Hits OEE: Availability

Symptoms: No label applied, the web snaps, machine stops on a label fault.

Web tension wrong or liner break

Set tension; re-thread; check the peel edge for nicks.

Label gap sensor not reading

Calibrate the gap or contrast sensor.

Empty roll or splice fault

Reload; manage splices to avoid stops.

Prevention: Tension setup, sensor calibration, roll and splice management.

Poor adhesion or lifting edges

Hits OEE: Quality

Symptoms: Labels lift, corners curl, or fall off after packing.

Surface dirty, wet or cold

Clean and dry the surface; control container temperature.

Wrong adhesive for the substrate

Match adhesive to surface and temperature.

Low application pressure

Increase wipe-down pressure and brush contact.

Prevention: Surface prep, correct adhesive selection, wipe-down setup.

Stop the same fault coming back

Recurring labelling machine stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: EU-built, so your production data stays in EU jurisdiction, with computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
