Holding air current

In processes for screwdriving in an upward direction, the screws have to be positioned and held in place so that they do not drop down. This can be accomplished in different ways. One is fixing by means of a holding air current. An air current is blown through nozzles, positioned between screwdriving head and nose piece, directly onto the screwdriving head. The screw which has been fed into position is held in place by this air current until the screwdriving tool has reached the screw.
