Failure modes to watch for
Every guide in the BHS Corrugated BHS Modular library lists the candidate root causes its procedure rules out. These are the distinct failure modes we've documented so far, a useful starting point if you don't yet know which specific alarm or symptom you're chasing.
Corrugating roll nip pressure set too high for the medium weight
Corrugating rolls worn or damaged, reducing effective flute height
Medium paper entering the single facer below the minimum temperature for forming
Starch application rate too high causing the medium to soften and crush
Starch viscosity out of specification, too thin for adequate coverage or too thick to gel
Double backer heat plates below the gel temperature for the starch formulation
Starch application rate insufficient for the liner surface porosity
Starch gel point temperature shifted from a formulation or water quality change

How to reduce flute crush at the single facer on a BHS Modular Corrugator
Flute crush at the single facer is caused by excessive nip pressure or dull corrugating rolls. Check nip load settings, corrugating roll surface condition, and paper temperature before adjusting.
How to diagnose glue bond failure on a BHS Modular Corrugator
Poor glue bond shows as low pin adhesion scores and delamination under flex. Check starch viscosity, gel temperature, and double backer heat before adjusting application rate.
How to reduce warp in corrugated board from a BHS Modular Corrugator
Board warp is caused by a moisture differential between the two liner facings. Check the moisture profiles of both liners, the double backer heat setting, and starch gel point consistency.
