This patent presents methods and apparatus for utilising a plurality of automatic screw- feed machines to feed a single outlet.

In one preferred embodiment the present invention comprises an arrangement of automatic screw-feed machines whereby each automatic screw-feeding machine delivers a different sized fastener to a manifold. The manifold includes a plurality of entrance ports connected to a common internal axial flow path. A single outlet port from the manifold is connected to a single delivery tube which feeds one of the fasteners from one of the screw-feed machines to a tool for applying the fastener. The entrance ports of the manifold are positioned at an angle to the axial centreline to provide re-orientation of the fastener position from the tube feeding the fastener to the manifold to the axial flow path within the manifold. The apparatus delivers one fastener at a time, whereby it is delivered to the remote location before another fastener is output from one of the screw feeding machines. Controls are also provided to change from one screw-feed machine to another.
