A dowel transfer station in a dowel driving device which includes a dowel separating and conveying unit and a manually operated driving gun to which dowels are supplied through a hose line. The dowel transfer station is arranged between the dowel separating and conveying unit and the hose line conducted to the driving gun. The dowel transfer station includes a reciprocating dowel holder which receives a dowel emerging from the dowel separating and conveying unit and supplies the dowel to the opening of the hose line conducted to the driving gun. For eliminating dowels which do not have the appropriate size, the dowel holder has a bore for receiving a dowel, wherein the depth of the bore is adjustable and the inner end of the bore is connected to a compressed air line which can be switched on and off by a valve. The plane of the outer opening of the bore in the dowel holder is arranged at a slight distance from the plane of the opening of the hose line and/or the plane of the dowel outlet opening of the dowel separating and conveying unit.
A dowel transfer station in a dowel driving device for transferring dowels having a predetermined length from an outlet opening of a dowel separating and conveying unit to an opening of a hose line for supplying the dowels to a manually operated dowel driving gun, the dowel transfer station comprising a reciprocating dowel holder, the dowel holder having a first bore, the first bore having an adjustable depth, a first end of the bore defining an opening and a compressed air line being connected to a second end of the bore, the compressed air line comprising a valve for controlling supply of compressed air to the bore, the dowel holder being movable between a first end position in which the first bore is in alignment with the outlet opening of the dowel separating and conveying unit and a second end position in which the first bore is in alignment with the opening of the hose line, the outlet opening of the dowel separating and conveying unit being located in a first plane, the opening of the hose line being located in a second plane, and the opening of the first bore being located in a third plane, the planes extending parallel to each other and being arranged at distances from each other, wherein at least one of the distances between the third plane and the first plane and between the third plane and the second plane is small, such that the movement of the dowel holder between the first end position and the second end position is blocked when a dowel is introduced into the first bore which has a length which does not correspond to an adjusted depth of the first bore.
