WIR REV Inspection Rewinder

The WIR REV print inspection rewinding machine is used extensively for the inspection and editing of printed substrates before onward lamination. The competitive environment of recent times has made this process an absolute must to keep converting wastages low.

The WIR REV runs in the forward or reverse direction, enabling the user to spot and bring back the defect to the splicing zone with precision, irrespective of individual response times. The full speed reversibility further boosts productivity by allowing the defect free reel to be restored to its original direction at full speed without unloading and re-loading.

As an alternate to manual inspection through a stroboscope, the inspection process can take the form of an automated response to the feedback from a 100% defect detection system.
