Surface inspection system
drello
For hole and crack detection on running non-transparent material webs
like aluminium foils, packaging foils or paper webs.
Applications
* Final control during foils or paper production and during processing of all non transparent web materials.
* Detection of faulty areas before processing, for example on printing machine.
* Quality assurance on rewinders and making up machines.
Product explanation
An infra-red light barrier scans the material web non-contact and over the full size (holohedral). By this faulty spots, as holes and cracks larger than 4 mm, are detected. In case a faulty spot is detected, a separate control unit gives an optical and accoustic alarm signal.
Moreover three alarm- active floating alternating contacts are available for assignment up to customer's choice (machine stop, etc.)
Due to the easy installation, connection and handling of the system, a problem-free application for most different processes and also on various machine types is possible. The system is not suitable for transparent material webs.
