This TAPPI technical information paper describes a practical method for evaluating whether corrugating rolls are parallel in a single facer. It explains required NCR paper materials, lockout/tagout safety precautions, setup and roll-jogging procedures, and how to compare flute-tip impressions from the operator and drive sides. The document also addresses microflute applications, roll wear, impression interpretation, and verification techniques for identifying out-of-parallel conditions.
Keywords: Corrugating rolls, corrugating machines, single facers, maintenance, alignment.
Application Scope: Intended for corrugated packaging manufacturing, single-facer maintenance, corrugator alignment checks, and technical personnel responsible for equipment operation and upkeep.
