Thank you Mr.Gari Blenkhorn,

But there could be few basic rules for deciding the answers of these queries.

1. If the gap between the successive plies is say 0.8 mm, what could be the insulation compound to be applied?

2. If the top cover & bottom cover thickness is say , 5 and 3 mm, what could be the cover compounds thicknesses? How much more should be filled than 5 & 3 mm ?

3. Before few years, I read in the manuals that the gap between leading & trailing plies was virtually nil. Almost touching each other. But now gap is recommended.

4. In my vulcanizing machine, the thermometer was showing 145 deg centigrades. But it was doubtful that if the total platen was having uniform temperatures. Hence having higher temperature would ensure melting of compounds fully. So I need the higher temperature for at least HR & M24 grade belts.

5. Edge bars are recommended at the edges. But why not old conveyor strips? This is particularly helpful when I join old belts or old & new belts.

There could be logical answers for all which I am requesting.

Thanks & regards, ■

Dear Mr.Graham Spriggs,

Cold vulcanizing method is not applicable for HR belts, as far as I know.

Dear Experts,

Cold vulcanizing joints may not give sufficient warning before their failure compared to that of hot vulcanizing joints.

Thinking further, conveyor belts are manufactured on hot vulcanizing method only.



I wish that they would be manufactured on cold vulcanizing method in near future.

Imagine the power & water saving on thousands and thousands of belt manufacturing across the globe and the other environmental benefits if they are switched over to cold vulcanizing methods! Sc 4000 are environment friendly.

Your comments please.

Thanks & regards, ■
