Preform™

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. Continental 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

Preform - Out with the old 

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 Method

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:

Preform Effect of Splice Preforms_con_jpg 

Testing on the 2-Pulley Dynamic splice tester at the Continental ContiTech 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:

Preform - Less Downtime 

Continental 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.
