Function
Flexible link between the motor and the machine which allows to transmit high power.
Each time you have beatings or horizontal movements of the belts, the banded belts VECOBAND cancell the twisting and avoid the shocks between the belts which
results in a lost of power and reduction of the life time (cruder, agitator, compressors,... )
In some of transmissions, the banded belts are also used for agricultural machines mainly to realize the clutch.
Conception
The banded belts VECOBAND are made of endless V.belts joined on their high base with a reinforced band. They are made of :
• synthetic rubbers which guarantee a constant hardness
• polyester cord with controlled elasticity and high capacity of traction
• single wrapping (for A and B sections) and double wrapping (for 3V, 5V and SPC sections) impregnated with polychloropren compound which resists heat, oil, abrasion and ozone.
Production range
• Narrow section belts :
3 V J (=9 J) : from 1 to 20 meters, 40 belts per band 5 V J (=15 J) : from 2,1 to 20 meters, 23 belts per band SPCJ : from 2,3 to 20 meters, 16 belts per band
• Classic sections belts :
A J : from 1,3 to 20 meters, 26 belts per band B J : from 2,1 to 20 meters, 22 belts per band The minimal quantity are following the sections and the lengths.

Lengths
• The belts are always specified by their effective length (ISO 8419 for 5V and 3V sections). This length corresponds to the external diameter of the measural pulleys.
• By construction this length is the same as the length of the cord.
• This length like the external diameter of pulleys can be used to do the calculation of your transmission (speed ratio,...). It is the same as the pitch length used usually.
• So, it is not use to calculate the pitch length, neither internal and external lengths : the effective length is enough to specify the belts.
