Why is there inadequate rigidity in the new belts in the first place?

These flexible sidewall belts seem to give you persistent headaches. I would recommend, as before, that you summon the services of the local representative of a reputable manufacturer. Few, if any, members of these forums are likely to have carefully "ripped the chords asunder" let alone tried to put them together to meet the original specification. Would it be worth the effort and expense. According to recent past posts your maintenance staff whinge about changing bearings. I cannot imagine what they would do when asked to do what you propose.

Re: Reusing Of Cross Rigidity Plies

Dear Mr.John Gateley,

As far as I know, there are no standards defined for steep angle belts , particularly for their cross rigidity. There are no measures during inspection prior to delivery or to predict their useful residual life in a normal operated steep angle conveyor. Such questions I have asked earlier. But did not get reply. I was given a comment by one of the members as " The belt manufacturers will not reveal such details as they could be their technical secrets". But as an end user, I should know the standards for this unique quality of steep angle belt. I am not asking their manufacturing details.

Even for same rating and specification, what kind of cross rigidity plies and their MOC ( Material of Construction ) is not well defined. Few manufacturers recommond fabrics and others metallic. Again each category, there are different materials. Every thing is related to cost.

Hence I am asking such questions. I have solved the problems araising out of bearings.

Thanks a lot for your concern and kind regards,

Reusing Of Cross Rigidity Plies

Dear Mr. Ganesh:

The best answer is that the appropriate splicing materials (for any belt) are always new and fresh materials.

That being said, to separate the cross rigid material will cause many issues; including, but not limited to damaging the material, the need to adequately buff the material for re-use, as well as the extra labor required to remove and prepare the cross rigid material without damaging it.

We have respliced many of these types of belts after other companies have used all sorts of materials for cross rigidity and it never works. The tremendous forces on these types of belts require the proper splicing methods and materials. The perceived cost "savings" will actually not be there when you have to shut down the system again to resplice or worse, if there is a catastrophic failure.
