To Skive Or Not To Skive: Things To Know Before Splicing ...

Aug 06, 2008  Stronger Splices. When a belt is skived, the top rubber layer from the belt is removed, placing the top and bottom plates of each fastener closer together, which ensures the teeth are properly engaged into the carcass. This improves the belt splice strength. For all of the above reasons, skiving is highly recommended when splicing your belt.

Splice Can Make The Difference - Dorner Conveyors

The v-guide splice under the belt is a very common failure point. The majority of suppliers utilize a skive splice for the v-guide, which is not ideal, but will typically work. Other suppliers choose to eliminate the v-guide in the splice area altogether, which usually causes inconsistent belt tracking as the splice goes over the end rollers.

The result can be a big pressure difference between the middle and the edges of the conveyor belt and maybe a bad splice. Consequently, if you want to vulcanize very wide belts, you need to calculate a progressive vulcanizing tool (thicker in the center and thinner on the corners) or you need a press with a “water bag” as pressure system.
