Abstract: A device with automatic feeder, for driving ribbon-mounted screws comprising a guide in front of which a box-like body is mounted so that it can slide longitudinally; moreover the body has a shallow seat for the sliding of the ribbon which is connected to a longitudinal hole for positioning the first screw and for the longitudinal sliding of the shank of the screwing tool and can be closed, in an upward region, by a sort of lid which is pivoted to the body and can be locked by means of a sliding bolt in the seat covering position; the seat is crossed by a lower tooth for retaining the first screw which is associated with a lever system; and a spring latch is mounted in the lid and is actuated so as to oscillate.
