Static pull splice strength tests conducted at an independent laboratory showed the Preform splice to be at least 10% stronger than a conventional splice. This one test shows that the Preform splice is able to withstand 33% more load cycles, which, in theory, equates to an increase in service life of 33% when compared with the conventional splice. Testing on the 2-pulley dynamic splice tester at the Continental technical center in Marysville, Ohio, shows the results of two identical belts, one spliced using Preform, and one spliced using conventional splicing methods. In an actual splice, cords would lead in from both ends of the belt, and the cord ends would not be wrapped as shown. ![]() This illustration shows how the top and bottom multi-groove panels encase each cord, eliminating the need for noodles and ensuring cord alignment. The above cross-sectional view illustrates the Preform concept and is not representative of an actual splice. The result is a stronger splice, with improved performance and a longer service life. Cord laying time is significantly reduced, and the correct cord spacing and alignment is virtually guaranteed. Cement drying times are eliminated, which reduces the possibility of splice contamination as a result of dust infiltration. Preform splices utilize preformed, multi-grooved top and bottom cover panels, which eliminates the need for cements and noodles. Position the stripped cords forming the belt.Position the bottom Preform panel on the bottom.Preform technology makes splicing simpler and less time-consuming. Not only is the process of spacing made easier, but the belt itself is made stronger. As the name implies, Preform is a pre-grooved form that simplifies splicing by allowing you to "sandwich" the cables coming from either side between the formed rubber. Preform splice technology from Continental. Cord misalignment and contamination are critical factors for the performance of the resulting splice. The alternative – the laying of cord and noodle, further extends splice time, as constant checking of the chalk line and adjustments to the noodle width are necessary to maintain cord alignment. Cement drying time extends the overall splicing time, thereby increasing the risk of contamination. Conventional splice methodsĬonventional splice methods involve the use of cements and rubber noodles. Continental’s Preform splices provide improved splice efficiency, along with reduced splice time and improved performance. There have been significant technical advancements in steel cord belt splicing over the past few years. Preform splice technology improves splice strength and saves time. ![]()
