Pulp

Pulp is the raw material for paper products, prepared by separating out cellulose fibers from wood or fiber crops. It is used to form a web structure which is bleached to create paper.

Because paper is formed from this web of pulp, accurate surface monitoring at the pulp machine stage ensures early detection and classification of any imperfections that might affect later processing.

Pulp is the basic building block of paper and is key to the production of all paper products, from paper sheets to car and cardboard products.

AMETEK Surface Vision has decades of experience in providing accurate web inspection systems to the pulp and paper industry. We have more paper industry customers worldwide than anyone else, all relying on our trusted solutions to safeguard their product quality and yield.

BENEFITS OF COLOR CAMERA INSPECTION SYSTEMS FOR PULP CONTAMINANT DETECTION
Color cameras have previously had a limited presence in automated surface inspection for the pulp industry. Existing installations have proven that inspection systems using monochromatic cameras are fully capable of detecting contamination in the pulp. However, there are some limitations to these cameras when it comes to distinguishing certain contaminants – for example, dark spots and color plastic. Read More >

Applications +
- Coater
  
  Paper can be coated to introduce or enhance properties such as surface gloss, ink absorbency and water resistance. High-precision monitoring can ensure uniform coating across a smooth surface.

- Extruder
  
  Extrusion coating involves molten synthetic resin being used to cover a moving paper web. Monitoring ensures a smooth, uniform coating and detects any hot resin damage to the paper.

- Folder
  
  Folding machines are used for making paper products, for example envelopes, and also as part of printing processes. Surface creases and other imperfections can be formed, and so monitoring is important.

- Paper Machine
  
  Pulp is squeezed through a series of rollers to remove water, then pressed and rolled further for a smooth finish, Surface inspection helps to ensure consistent paper quality.

- Printing
  
  Mass printing for newsprint and magazines is a high-speed rolling process that depends upon smooth, defect-free surfaces to ensure a legible product. This requires a fast, automated inspection solution.

- Rewinder
  
  Once the master roll is unwound and slit, it is then rewound onto smaller cores of the desired size. Monitoring can verify surface condition and ensure web integrity.

- Sheeters
  
  Paper sheeters cut the paper roll to size for further use. Automated inspection can check for imperfections before the final product is used or packaged for dispatch to customers.

- Wrapping
  
  Automated wrapping increases production speeds, but requires a monitoring solution that operates in real-time. Surface defects can impair packaging integrity and result in a damaged or unappealing final product.

- Winder Slitter
  
  Winder slitters are used to cut large-diameter paper rolls into trimmed roll widths which meet customer requirements. This can be a hazardous area for manual surface inspection, so an automated solution is recommended.

- Pulp Dryer
  
  The chemical-based Kraft process produces a strong pulp mixture that is sprayed onto a moving mesh screen. Web and surface inspection will reveal any flaws at the drying stage of pulp production.
