ARC’s knurled roller works together with the upper feed roller to pull the corrugated sheet into the print section. The lower Knurled Roller must have a consistent pattern that is free of rust, wear, dried ink and other imperfections. When this is combined with your feed roll it delivers the best results.
Knurled Rollers in steel or other coatings are also available with a variety of patterns such as Diamond Pattern and Horizontal Groove to suit your needs
