An apparatus for tying a wire 46; 52 around one or more objects such as concrete reinforcing bars 2 is disclosed. It comprises means for passing the wire 46; 52 in a loop around the bars and a rotatable head 4 for twisting the ends of the loop together. The head 4 has at least one gripping means such as a variable force clutch 32 for gripping the wire, the gripping means being adapted to provide a variable gripping force so as to apply a predetermined tension to the wire during at least a first phase of twisting. Also disclosed is pre-feeding the wire between tying operations; conditioning the surface of the wire; and using the electrical conductivity of the reinforcing bars to verify that the bars are present before tying.
