A particular product finds application where security is important, such as in labels and security envelopes. This product requires a water-based adhesive to be applied to a high value stock before a laminate is applied to the adhesive. In some cases, the laminated product is re-passed through the adhesive station so that the laminated layer itself carries a layer of surface adhesive.
Previously, the adhesive was dried in a warm air oven but this sometimes caused problems when drying coloured adhesives, with “spotting” or reticulation, which created an uneven and visible adhesive pattern on the substrate. As a result it was necessary to slow down the line to around 20m/min.
In an effort to solve the problem, Smith & McLaurin contacted Heraeus, who supplied a portable infra-red module to allow tests to be carried out on site. These proved so successful that a 32.5 kW, system equipped with five carbon medium wave emitters was installed immediately before the existing warm air heaters. The emitters are individually controlled so that they can be switched on and off according to the coating weight.Iain McCourty, Engineering Manager at the Renfrewshire site, explains, “By using the infra-red heaters to direct an initial burst of energy at the wet adhesive we have been able to eliminate any “spotting”. This has meant that we have been able more than double line speed . It has also meant that we have been able to guarantee quality which has helped to consolidate our relationships with customers.”
Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China and Australia, is one of the technology- and market-leaders in the production of specialist light sources. In 2011, Heraeus Noblelight had an annual turnover of 103 Million € and employed 731 people worldwide. The organization develops, manufactures and markets infrared and ultraviolet emitters for applications in industrial manufacture, environmental protection, medicine and cosmetics, research, development and analytical measurement techniques.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
