| 1. A device for closing valved bags, having a projecting valve, for containing powder or granular materials, suitable for
installation within a belt, roller or similar line for conveying bags, comprising:
at least one sealing head; and
a conveyor means for feeding the bags to the sealing head,
wherein the sealing head presents drive means causing the sealing head to advance, during the sealing process, at the same
speed and direction as the conveyor means and to simultaneously move the sealing head in a direction perpendicular to the
direction of the conveyor means to enable the sealing head to seal the projecting valve of the bag while the conveyor means
is moving,
wherein the drive means comprise a guide on which the sealing head is slidable, and
wherein the guide is inclined to a resting surface of the conveyor belt.
