Splicekits

Preform™ patented splice technology improves splice strength and saves time.

There have been significant technical advancements in steel cord belt splicing in the past several years. ContiTech patented Preform™ splices provide improved splice efficiency, along with reduced splice time and improved performance. This means more dollars in your pocket.

Conventional splice methods

Conventional splice methods have been utilized for many years. When it is possible to obtain satisfactory performance, the many components involved create time-consuming splices. Splicing is an art, dependent on the experience and expertise of the Individual splicer.

Conventional splice methods involve the use of cements and rubber noodles. Cement drying time extends the overall splicing time, while providing the opportunity for increased contamination. The alternative laying of cord and noodle, further extends splice time, as constant chalk line checking, and adjustment to the noodle width is necessary to maintain cord alignment. Cord misalignment and contamination are critical factors in the resultant splice performance.

Preform™ splice methods

Preform™ splice technology from ContiTech. A conveyor belt revolution. Like the name implies, Preform™ is a pre-grooved form that that simplifies splicing by allowing you to "sandwich" the cables coming from either side between the formed rubber. Not only is the process of spacing made easier, but the belt itself is made stronger. Preform technology makes splicing simpler and less time-consuming.

  • 1. Lay the bottom Preform™ panel down.
  • 2. Lay in the stripped cords form the belt.
  • 3. Lay down the top Preform™ panel.

Preform™ splices utilize preformed, multi-grooved top and bottom cover panels, eliminating the need for cements and noodles. Cement drying times are eliminated, reducing the possibility of splice contamination from dust infiltration. Cord laying time is significantly reduced, and the correct cord spacing and alignment is virtually guaranteed. The result is a stronger splice, with improved performance and life.

The above cross-sectional view illustrates the Preform™ concept, and is not representative of an actual splice. This illustration shows how the top and bottom multi-groove panels encase each cord, eliminating the need for noodles and ensuring cord alignment. In an actual splice, cords would lead in from both belt ends, and the cord ends would not be wrapped as shown.

Improved performance

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. This one test shows the Preform™ splice to withstand 33% more load cycles, or a theoretical 33% longer service life, than the conventional splice. Static pull splice strength tests conducted at an independent laboratory showed the Preform™ splice to be at least 10% stronger than a conventional splice.

Savings

ContiTech Preform™ splices have been made successfully in many countries around the world. Savings of 16% to 25% were based on actual filed measurements, comparing one splice technique versus the other, on the same belt, at the same time. Reduced splicing time means more up time and increased productivity.
