Lamination bond strength is set by nip pressure, adhesive coat weight and cure — and nip pressure is rarely uniform across a wide web once rollers have worn or deflected. The defect this produces, delamination, does not appear at the machine. It appears later, sometimes weeks later, in a converted product at a customer's site, which makes it one of the most expensive quality failures in the plant.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

Product ships. Edge delamination and tunnelling show up downstream, and because the roll was inspected and passed, the investigation starts with the customer's handling rather than the nip profile. By the time the cause is found, several weeks of production have shipped with the same latent defect.
Quarterly nip-profile measurement across the full width, with bond testing on every job. Any new substrate or adhesive combination justifies a check before the run rather than a bond test afterwards.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
