Richard Hough to unveil new roll covering technology

Richard Hough Limited manufacture a specialist range of rollers for the finishing and processing of paper, textiles and metals. Applications include paper supercalendering, textile calendering and squeezing, embossing and sheet metals.

Richard Hough Ltd. (RHL) has collaborated with Just Rollers plc, a supplier in elastomer roll coverings, to develop the new Resilio system. Trials identified substantial performance benefits over the existing systems in the market:

• Typically 40% better expression on knitted goods.
• Typically 18% better expression on wovens.

Cost savings are equally significant, potentially reaching as much as 50,000 euros per year depending on the applications, according to the company. The Resilio roll will be officially launched at the ITM 2009 textile machinery exhibition, to be held in Istanbul, Turkey from June 6 to 10.

Richard Hough Limited have recently introduced a high performance polyamide textile calender roll cover to their range.  Roll edge marking and web defects due to roll surface marking have been virtually eliminated, meaning greatly reduced quality defects and significant savings in production costs.

Syncast™ is a uniquely elastic, thermoplastic polymer that has been specially developed for textile calender rolls. Syncast™ roll covers are centrifugally cast at high speed (2000m/min), ensuring the expulsion of all air bubbles and impurities from the cover. Internal stresses are minimised as Syncast™ is cast at temperatures below the melting point of the polymer. Optimum molecule length gives the Syncast™ roll cover excellent elasticity and mark recovery, with minimum shape distortion. Syncast™ roll covers are fully annealed and ultrasonically checked, guaranteeing optimum quality and performance.
