Preventive + Maintenance = Quality

Brian Ivens, Arpeco (www.arpeco.com), offers, “The components that most often need replacing are the slitting knives, but I am sure that this is self-evident. After that, items related to the web transport are next, specifically nip rollers and nip roll gears.” Nip rollers, he says, wear depending on material type and width, and nip roll gears can be damaged during frequent, high-speed stops and starts, as well as during material wrapups. He adds, that in older machines, other parts such as brake and clutch friction discs and pads wear out. In general though, Ivens suggests that when it comes to maintenance, “converters should consider all areas of the machine that can affect web transport and processing accuracy.”
