LS 375

Low cost web inspection system.
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.
