New Technology Improves Splice Strength

Preform conveyor belt splicing from Goodyear Engineered Products is claimed to cut mine operation downtime and createstronger splices. Goodyear says tests indicate the patented splice process offers up to 33% more dynamic life than conventional splices, which require the installation of individual rubber strips called noodles between each steel cord across the width of the belt. To keep the cords and noodles in position, rubber cement is applied before top and bottom rubber panels are put into place. Designed exclusively for Goodyear Flexsteel conveyor belts, Preform splice technology uses preformed, multigrooved, top-and-bottom panels that replace noodles, insulation gum panels and cement. Individual steel cords are properly spaced and aligned, requiring no cord cement which eliminates drying time. Static-pull splice strength tests conducted at an independent laboratory showed that Preform splices were 11% stronger than belts tested with conventional splices.
