| Characteristic |  | Possible problem |  | Solution |
 |  |  |  |  |
| Splice fails (rupture of reinforcement) |  | Belt tension too high |  | Modify conveyor to reduce the belt tension (e.g. increase speed, reduce running resistance, increase friction between drive pulley and belt) |
|  |
|  |
|
| Splice fails (separation between splice steps) |  | Old or wrong splicing material |  | Resplice belt with correct splicing material, do not exceed maximum storage time |
|  |
|  |
|
 |  | Rubber solution not evaporated sufficiently |  | Resplice belt, let rubber solution evaporate well |
|  |
|  |
|
 |  | Ambient conditions during splicing too humid |  | Resplice belt, provide rain protection, heat belt ends (max. 80°C) before final assembly |
|  |
|  |
|
| Splice opens in belt centre |  | Compression of belt centre in transition area |  | Increase transition length, elevate the pulley 1/3 of the trough depth, increase pretension |
|  |
|  |
|
| Splice opens or break at belt edge |  | Tension at the belt edge to high |  | Increase transition length, elevate the pulley 1/3 of the trough depth, reduce pretension |
|  |
|  |
|
| Splice opens or breaks at the bottom side |  | Compression on the bottom side |  | Increase pulley diameter |
|  |
|  |
|
| Fasteners pulling out |  | Wrong type of fastener or fasteners not tight |  | Refasten belt with right fastener, retighten new fasteners after a few hours run |
|  |
|  |
|
 |  | Tension to high |  | Change type of fastener, decrease belt tension |
|  |
|  |
|
| Transverse breaks in the belt right behind fasteners |  | Fastener plates too long for pulley diameter |  | Use smaller, shorter fasteners |
|  |
|  |
|
 |  | Fasteners too big |  | Increase pulley diameter |
|  |
|  |
|
| Cover strip separates from splice |  | Pressure during splice too low |  | Replace cover strip, increase pressure of vulcanizing press |
|  |
|  |
|
 |  | Cover strip to thin |  | Replace cover strip by thicker type |
|  |
|  |
|
 |  | Joint sections of rubber covers cut too steep |  | Replace cover strip, cut cover less steep |
|  |
|  |
|
 |  | Joint sections not ground |  | Replace cover strip, grind/roughen joint section |
|  |
|  |
|
 |  | Uneven transition allowed belt cleaner to rip off cover strip |  | Adjust belt cleaner, smoothen transition in splice section |
