The A-I models represent the evolution of the conveyors model 9 towards the unification of a single solution suitable for all types of chip.
The A-I conveyors integrate the mode of operation forwards (hinged conveyors) with the mode of operation backwards (dredging conveyors). Thanks to a special construction technique, the two directions coexist allowing the machine to work alternatively both forwards and backwards. Thus, the operator is free to choose the most suitable mode of operation for the chip he is producing.
