Slip-Torque® conveyor technology was pioneered by Shuttleworth in 1972 and has evolved through over thirty years of practical application in numerous industries. It is based on polished stainless steel shafts individually powered by flexible belts on a line shaft or by a continuous chain. These stainless steel shafts are covered with segmented, loose-fit rollers, which become the conveyor surface.
It is the weight of the product being conveyed combined with the coefficient of friction between the shafts and the inside diameter of the rollers that provides the driving force. As the weight of the product increases, there is a corresponding increase in the driving force supplied. As products stop, the segmented rollers beneath them also stop, creating very low backpressure accumulation and reducing product damage.
