That is a very vague and general question. Multi-ply or what? All splices should be done as per the belt manufacturers recommendation.

Is this a butt joint splice or a finger jointed splice?

I would never do a butt jointed splice without a bias. A bias give much greater length for the strength of the splice. The greater the bias the stronger the splice. The longer the tie fabric will be.

But this would all depend on the application and the splice should never be done without the belt manufacturer's recommendations being followed. ■

Dear Mister Ganesh,

I have found right now your request and want to inform you as follows:

For steep angle belts - cross rigid belts - you should make the endless joint rectangular.

Please have therefore also a look on our website.

If you are interested into our brochure for Belt conveyor technology please let us know your exact address.

With kind regards

As I know, there are two principle reasons for the bias splice pattern:

1. As Gary has noted, the longer splice overlapping ply shear length and therefore higher splice strength rating. However, longer length means longer and costlier splice vulcanizer. There are other ways to achieve higher splice strength ratings.

2. Splice leading edge enters the pulley at an point rather than a line across the belt width, thereby reducing the impact of the splice joint and consequential stress on belt, drive system, and pulley assemblies. This is a bigger problem with multiple driven pulleys and normal troughed belts.

3. Some are now practicing high strength steel cord belt splices with rectangular configuration to reduce the physical size of the vulcanizer.

There may be other good reasons as known by others yet to be publish. ■
