As its name suggests, an inspection slitter rewinder (ISR) machine does many things - although not necessarily in the expected order. ISR machines made by Oakville, Ontario-based KOR Engineering Inc. are specifically designed to slit, laser perforate and inspect a wide range of pressure-sensitive labels, flexible packaging and shrink sleeves.

When designing a complex machine, engineers have two options. They can get all parts of the system—controller, drives, motors, I/O and human-machine interface (HMI)—from a single vendor. Or, they can pick and choose devices from mul-tiple suppliers.
