Abstract
The present invention proposes a device for control of the presence of conductive bodies or materials in bales for processing in bale-breaker machines equipped with rotating members for the take-off of fibre locks from the bales disposed in a row and also equipped with pressure elements resting on the upper surface of the bales being processed. The device comprises conductance sensors associated with the pressure elements and sensitive to the conductance existing between said elements and forming part of an electric circuit adapted to cause the machine to be acted upon in such a way as to prevent damage to the rotating take-off members when the conductance between any of two contiguous pressure elements exceeds a pre-set value. The result of the machine being acted upon may be the halting of the rotating take-off members and/or a raising of such members and possibly a simultaneous cut-out of the machine.
