The cracking problem could relate to the poor splice execution. The belt splicers used do not appear to be at all competent if your description of the splice is accurate. Cutting cables out of a splice is usually done because the cable lay up has been poorly executed. This in turn can be caused by using tie gum that is too thick. Once cables have been cut out of a splice you cannot just re-lay the splice as the balance may now be all wrong. Find someone who knows how to splice steel cord belt is your starting point

Perhaps insist on a stamped belt splice and XRAY image of the spilce as well as their QA/QC and certificates of test/quilifications etc. No payment until these are received.. ■

Dear Ravindral,

Depending on the type and direction of the edge zone (i.e area outside of the sidewall boudries) cracking, possible causes can be from the stresses resulting from your side guide rollers or from the stub return idlers. Note that I am assuming that this is a corrugated sidewall belt with sidewalls of 8 inches or higher.

The side guide roller can fold the belt edge, thereby causing cracking - normally on the bottom cover and edges.

The stub idlers can cause cracking as the belt bows - normally on the top cover. Good cross-belt stiffeners help to prevent this problem.

Very interesting..

I seem to recall mentioning to Don and Russ at Essar when I was there that you may have a lot of trouble with those pocket belts.

Why not ask them for a copy of my report.

(And please give them my regards)
