Product range highlights:

Resilio Squeezing Rollers

RHL has collaborated with Just Rollers plc, to develop its revolutionary new Resilio roll covering technology for fabric dewatering applications. Dramatic improvements in water expression and major cost and energy savings in drying can be achieved with Resilio rolls. Extensive trials have identified substantial performance benefits over the existing market-leading elastomer roll cover - typically 40% better expression on knitted goods and 18% better expression on wovens.

RHL has applied for a patent for the new Resilio roll, which utilises a specially-developed dual-layer cover technology. The secret is in the integration of the squeezing power of a hard rubber sub-layer with a revolutionary profile-hugging softer rubber top layer, devised by RHL.

Syncast Polyamide Rollers

RHL's Syncast calender rolls have rapidly become the world's market leading polyamide calender rolls. Syncast polyamide calender rolls are a state of the art solution for many textile calendering and embossing applications. Excellent resistance to surface damage ensures minimum maintenance and a very long service life. Syncast can be supplied as a complete roll or the Syncast sleeve can be supplied to a customer's required specification. Syncast rolls can be produced with a face length of up to seven metres and diameter of up to a metre with either parallel or crowned profiles. Syncast sleeves are spun cast on industry leading equipment, fully annealed and ultrasonically checked, guaranteeing optimum quality and performance.

Cotton Calender Rolls

RHL's Cop Cotton calender rolls are produced to the highest quality and are specified by the world's leading calender manufacturers. The company's industry leading 3,500 tonne hydraulic presses ensure the maximum cotton roll density which guarantees the highest calendering performance and roll service life. RHL cotton rolls achieve the optimum surface finish on woven and knitted, natural and synthetic fabrics.
