Web Inspection for Tissue Mills

Web Inspection Solutions to Tissue Mills

Procemex Web Inspection System provides you continuous detection of all paper defects plus a seamless
integration to OnePlatform System. Procemex develops and manufactures their own Matrix Smart Camera and
LED lights specifically for the pulp and paper industry.

High Quality Photographic Imaging

  • Matrix Smart Camera provides superior image quality with high speed machines
  • Smart Camera auto shutter provides even exposure and illumination over multiple grades and shades of color, which enables fully automated grade settings
  • Industry leading camera sensor light sensitivity and image bit depth
  • Up to 700 MHz real time data processing inside the camera which is over 5 times faster standard Gig-E Data Protocol solutions

General System Features

  • Reel number and paper grade imported and displayed
  • Hide and unhide defect classes on scrolling defect map
  • Possible to zoom in or zoom out defect map to cover several paper reels at the same time
  • Planned customer roll set can be overlaid on the defect map and defect density by roll can be highlighted by color
  • Repeat defect alarms based on 100+ machine elements such as fabric length or roll diameter
  • Defect trends and reports by user defined time period
  • Formation measurement
  • TAPPI/ISO – dirt count capable

Powerful LED Strobe Lighting

  • Smart Camera pulses LED strobe only during image exposure; reducing heat generation due to decreased illumination time which significantly extends the life of the LED
  • Strobing provides powerful illumination peak to stop the web movement, eliminate blur and produce photographic image quality
  • Any LED segment can be changed at any time without creating a degradation in detection performance and the overall capabilities of the system

HD Pinhole Cleaning Concept

Web Inspection is typically located at the end of tissue machine in dusty environment. Unique patented pinhole camera beam or separate pinhole camera housing keep cameras clean.

Different Detection Geometries

The Smart Camera can make several independent measurements by pulsing different LED light profiles to flash
sequentially for alternating inspection.

Utilizing Procemex carbon fiber beams guarantees evenness of illumination and a long-term alignment of cameras and lights. In case there is not enough space or if a lower price option is preferred, it is also possible to use separate
cameras and lights for the same purpose. This leads to more uneven illumination and extra maintenance/alignment work on cameras and lights is necessary over the lifetime of the system.

Alternating Light Web Inspection


  • Matrix camera imaging provides higher quality images to the classification engine and increases accuracy over antiquated line-scan technology
  • Procemex utilizes a floating defect filter to reliable separate defects in the sheet from floating dust and debris in the area
  • Smart Camera enables direct pre-classification in the camera and real-time outputs are available for external use
  • Post-classification beyond single inspection frame measurement utilizing all data available for the most accurate classification
  • Advanced Classification utilizing the VisionAppster Platform for developing and acquiring tailored traditional and neural network classification algorithms

Automatic Target Control | ATC

A marker located at the end of the tissue machine puts an ink code with the MD position information on the edge of the sheet. A reader on the winder reads the code and synchronizes the defect map with the actual current position and enables an automatic stop or crawl function to react on customer defined defects.

  • Automatic reel and defect map loading
  • Customer roll set position can be overlaid
  • Selected slow down or stop targets indicated on defect map
