A forming station for forming single sheets of over-wrapping material is arranged near the trajectory and includes a feeding device for feeding the sheets in a U-shape, synchronized with the first grippers. A first drum transports formed bags, rotates about a second axis and has grippers receiving the bags from a preceding station and releasing the bags from the first grippers with the U-shaped sheets in synchronization. A closing station includes a sealing gripper movable from a first position near the carousel, for picking the bag with the sheet the first gripper, to a second away position for closing the sheet and, lastly, to a third position near the carousel, for release of the enclosed bag to the second gripper.
