An apparatus for tying a wire around one or more objects, such as concrete reinforcing includes a wire feed roller configured to pass a wire around the objects to form a loop, a wire twister configured to twist the sides of the loop together, and a guiding surface arranged to deflect the wire as it is being twisted so that the ends of the wire finish pointing at least partially in the direction of the objects being tied.

Apparatus for tying wire around one or more objects

An apparatus for tying a wirearound one or more objects such as concrete reinforcing barsis disclosed. It comprises means for passing the wirein a loop around the bars and a rotatable headfor twisting the ends of the loop together. The headhas at least one gripping means such as a variable force clutchfor 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.
