Roll alignment using modern measurement service PARALIGN
In paper and converting plants, roll parallelism and geometrical alignment
to the reference line are very important to ensure product quality and machine availability.
Non-parallel rolls cause a transversal force leading to asymmetrical tension of web. This leads to tears, wrinkling, and frequent wire replacements.
Traditionally, theodolites were mainly used for measuring roll parallelism. However, optical systems quickly reach their limits in industrial environments, as a line of sight to the objects to be easured is required at all times.
PARALIGN is a innovative measuring device using aerospace technology to align rolls in web-conveying plants such as paper mills, converting and packaging machines.Download the case study
