Paper Specialty

Specialty papers possess specific characteristics and properties designed for a specific end use. This type of paper often requires closer monitoring for quality control than ‘standard’ paper.

Paper designed for specific applications often requires special chemical coatings. This process benefits from surface inspection systems which detect imperfections at an early stage, protecting quality and increasing yield.

Specialty paper is a profitable segment for the industry, and encompasses applications such as currency notes, decorations, coffee filters, colored paper and carbonless copy paper.

With deep applications knowledge and extensive experience in the paper industry, AMETEK Surface Vision is the ideal choice for your web inspection system. Our customized, tailor-made-solution approach offers the best results for the unique installations dealing with specialty paper processes.

SURFACE INSPECTION SOLUTIONS FOR METALLIZED PAPER
Metallized paper is produced by coating paper with a thin layer of vaporized aluminum, giving it a finish that adds decorative and protective properties to the product. It is primarily used in packaging, for example in labels, inner liners, gift wrap and other consumer product applications. 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.

- 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.
  
  Keep Reading
- 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.

- 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.

- Winder
  
  Winders convert machine-width paper rolls into finished roll sets for converting or shipping. Paper from a parent reel is rewound onto a core and slit or trimmed as required.

- 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.
