ABSTRACT:
The invention relates to a binding tool for twisting the free ends of a binding wire, particularly for holding together metal reinforcing rods at their crossover points. The tool has a feed device for the binding wire, at least one pair of wire guides which can be opened and closed like pincers and which form, in the closed state, a U-shaped wire guide path, in use, around an assembly to be bound, shears for cutting the advanced wire to length and a twisting head which can be driven and which has wire passages to receive the ends of the wire to be twisted, the wire feed path extending, when the twisting head is in the position of rest, through one wire passage therein and, via the U-shaped wire guide path into the other wire passage in the twisting head. The twisting head is disposed in the space between the wire guides of the or each pair and the wire passages in the twisting head are formed in components which can be swung inwards about bearing pins.
