Bi-directional Inspection Machine

ServoTech B 400 HS

Inspect-Reinspect-Slit-Rewind

The B400HS Label Inspection Slitter-rewinder was launched at the LabelExpo India 2016 show. This machine has been designed for critical inspection requirements, particularly in the Pharmaceutical sector. This machine offers fail-safe inspection of printed label rolls through its Re-inspection Mode. When a defective label is captured by the Inspection camera the machine brings the label to a splice table where the operator confirms the defect and replaces the defective label. When the machine is re-started, the replaced label is re-inspected by the Camera to confirm that it is defect free. This mode of operation offers fail-safe defect detection.

The machine is also capable of on-line slitting and rewinding during inspection and has a top conversion speed of 300 meters per minute. The slitting system is fast to set-up and is precise and offers fine slitting quality for a variety of label stock substrates.
