Preventive + Maintenance = Quality

What wears out?

Knives are the parts that wear out the most in slitting systems, according to everyone who spoke with packagePRINTING. But these aren’t the only parts that need to be addressed.

Knives wear at varying intervals, with the top blade needing to be replaced before the lower knives. The interval, according to Smith, depends on the material being slit and the speed and percent of running time of operation. “This could be as short as one day or as long as one month,” he says. “The bottom slitter blades also need to be replaced on a routine basis, which is always much longer. This would typically be every three months to yearly.”
