Paper Machine

Paper machines operate through a continuous process that takes rough, wet pulp at one end and outputs smooth, dry paper at the other. The paper is fed through in a continuous web, which may need to be monitored for tears and breaks.

Paper machines generally have four sections. The forming section is where the wet web of fibers is created, while the press section uses high-pressure rollers to remove water. The drying section uses steam-heated drying cylinders, and is followed by the calender section where the dried paper is smoothed under high pressure. Some machine also use a coating section.

As a continuous process with several stages, paper machines benefit from automated surface and web inspection systems. This helps alert operators to potential web breaks, and supports quality of the paper produced at the end of the process.
