Quality inspection system for blanks PLUSTER

Introducing the world’s first inspection system for blanks to be capable of testing clear cartons and unusually shaped media!

In addition to high processing throughput with high-speed media transport at up to 200 meters per minute, PLUSTER is designed to protect media from damage during transport, including defective products being stacked.

Webtech’s proprietary functionality for automatically identifying media shape underpins a totally automated system that extends from master registration to area setup and inspection. Multi-touch monitors designed for maximum operator ease of use keep things streamlined and reduce workload and hand movements.

Inspect one-touch and unusually shaped media that would be impossible to test with inspection systems for blanks that use transport-style inspection methods.
