At the forefront of non-contact drying technology


on 80 years of experience that originated in the textile business, the UK-based specialist provides custom-built solutions in the paper industry for the drying, cooling and non-contact web handling for a wide range of base papers, coated papers and sized paper grades. Says Spooner’s marketing specialist Lee Fairhurst: “All of our four basic technologies were devised and developed by Spooner. We do not produce these products as a standard piece of kit – a potential customer will normally come to us with an issue and we will provide them with a tailor-made solution based on our experience and technology.” Spooner’s equipment for paper


D


makers includes: • Machine glaze (MG) Hoods/


Yankee Hoods: Developed many decades ago by Spooner for


on’t expect off-the- shelf drying systems from Spooner Industries. Calling


machine glaze and tissue grades, this specialised equipment enhances the drying capacity of the MG/Yankee cylinder by using high-velocity air impingement on the reverse side of the sheet. The Spooner hoods are now available with high performance internal air systems and are capable of air temperatures of up to 600 deg C. • Air Turn: Developed to


provide non-contact turning of wet coated webs, the Spooner Air Turn (pictured) provides stable operation with no web


edge flutter or vibrations and is suitable for heavy or lightweight grades. A special design also is available for porous webs. • HPC Dryer: The HPC compact air flotation dryer doubles the airflow of a conventional air flotation dryer through a unique configuration of air flotation airbars supplemented by an equal number of hole impingement airbars. This increases performance by a proven 30 per cent or more whilst the high heat transfer potential, resulting in shorter


machine lengths, is particularly effective for drying applications where space is limited such as online coat drying on paper machines. Width capability is up to 10 metres. • ModuleDryer: By providing simultaneous non-contact turning and drying, performance within a particular space is maximised. The ModuleDyer combines the non-contact web turning capability of the Air Turn with the heat transfer capability of a high performance air flotation dryer. Says Fairhurst: “The strength


behind Spooner is the wealth of accumulated knowledge and expertise which ensures in-depth understanding. Problem solving for customers’ new or refit requirements is the operational norm, with tailored solutions designed and engineered always to provide optimum results.” More information from Spooner Industries Limited, Railway Road, Ilkley LS29 8JB, UK.

Heat-resistant dryer fabrics launched by Voith


Two new heat-resistant dryer fabrics have been launched by Voith. Pyrox and PyroxHigh are part of the CleanWeave family of dryer fabrics and were specifically designed for dryer sections with moderately high temperatures. Pyrox fabrics are made


from a blend of hydrolysis resistant PPS and abrasion resistant PET materials. Like the entire CleanWeave product family, Pyrox and PyroxHigh is produced from SynStron yarn,


a material developed by Voith that is especially suited for the challenging conditions of the dryer section. The proven weave structure of CleanWeave dryer fabrics is incorporated in Pyrox and PyroxHigh. It offers a low internal void volume and minimum yarn crossover points, ensuring reduced contamination within the fabric. The compact fabric structure simplifies cleaning of the surface to ensure


constant permeability. All CleanWeave products from


Voith have a stable, easy-to-clean fabric structure that is unique in the industry. This ensures that the fabric remains close to its original air permeability, maximizing drying and sheet


handling over its service life. More information at www.voith. com/paper.
