Our WIS1000-system detects and classifies low contrast defects in plastics, paper, film, foil, non-woven materials, and many other substrates, produced at high speed.

It provides a total quality solution for most web produced materials.

​

Advanced line scan cameras capture high resolution images of the moving web. The cameras and lightsources are mounted at specific angles to maximise the contrast of possible defects in the material: gels, contaminants, holes, bubbles, stains, coating inconsistencies, streaks, …

These defects will be classified on type and size. The defect images with detailed information are displayed and stored in a roll data base for verification and process optimization. Summary reports and trend charts are generated and can be converted to  common used formats.

Key advantages:

​

• high performance

• reliable and fast defect classification

• easy to install and operate

​

​

Main features:

 

• inspected web width range from 10 mm to 10 m

• web speeds up to 1000 m/min

• up to 4 webs can be defined and separately reported

• automatic gain control, flat field correction, automatic edge tracking and opacity      control on all webs

• detection and classification of defects as small as 5 micron (dependent upon # of cameras and web width to be inspected)

• classification based on contrast, shape, model recognition, width, length, surface and density measurements

• supports up to 32 user definable defect categories

• operates in transmission, reflection or any combination of any angles

• real time or distance delayed alarm outputs triggered on discrete defects or density exceedings (sheeter applications, tab throwers, spray markers)

• OPC-connectivity (UA)
