Forming and Press Section Web Monitoring & Web Inspection

Home / Web Monitoring / Forming and Press Section Web Monitoring & Web Inspection

One-profile measurement geometry for monitoring web breaks, detecting and classifying  surface defects and inspecting fabrics

Procemex wet end pinhole frame technology carries several international patents and enables to locate a full width inspection frame at critical forming section and press section positions.

Typical positions are forming table,  former/press transfer, under pick-up felt and exit press section. Also difficult environments can be found around size press.


The unique benefit is that cameras and lights stay clean under harsh wet end locations. The pinhole camera cleaning solution and light cleaning solution has been perfected since first installation in Finland in pick-up position in 2013.  

Superior Tool for finding Root Causes of Web Breaks

With the traditional web monitoring cameras located on the sides of the paper web in the press section, you can view only those defects, that are located close to the paper edges. Should the defect be in the middle of the web, the web monitoring cameras aren’t your best tools for finding the defect. And even if the defect was located close to the paper web edges, the traditional web monitoring cameras many times are too dirty to provide sharp enough images that would help you.

This is why pick-up web inspection is a game-changer. A web inspection frame located in the paper machine’s pick-up point captures the defect images sharply and from the entire width of the paper web.

  2. Web break caused by insect, defect image from press section.
