bored plaques 9 inserted inside the metal net 8 where the upper plate 3 results partially overlapping over the following base plate 4 plates 3 and 4 thus coupled stay integral and form a single body even when wrapping on drums 5 the bores on the lower plate 4 are slotted to allow for a differential expansion between the plates 3 and 4 due to different thermal conditions in case of such realization of plates 2 elements 3 and 4 may be of different thickness and different material from each other allowing for both the ideal choice for the material in contact with the product to be transported and the choice of the total thickness necessary to convey sturdiness to the conveyor belt according to transport needs for this reason the conveyor belt object of this invention can be considerably sturdier than those according to prior art because this configuration with coupled plates 3 and 4 fixed to the net traction belt 8 allows to use considerable thickness without any difficulty in sliding on the return wheels 14 the close pitch of the load bearing rollers 13 gives sturdiness and reliability to the conveyor belt 1 absorbing possible impacts deriving for example by heavy weights hitting the conveyor belt 1 the resistance to mechanical stress of.
