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. Our
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 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 mis-alignment and contamination are critical factors in the resultant
splice performance.

This illustration shows how the top and bottom multi-groove panels encase each cord, eliminating the need for
noodles and ensuring cord alignment.
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.
Improved Performance
Testing on the 2-Pulley Dynamic splice tester at our 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 splices have been made successfully in many countries
around the world. Savings of 16% to 25% were based on actual field
measurements, comparing one splice technique versus the other, on
the same belt, at the same time. Reduced splicing time, means more
uptime and increased productivity.
