Abstract: A binding wire guide mechanism in a binding machine has a bend guide member which is provided at the outlet of a straight guide member. The bend guide member has a wire receiving surface which receives a wire fed through the straight guide member in such a manner that the wire abuts obliquely against the surface.

The bend guide member is short, providing a free space at the front. Therefore, the wire can be positively wound around the articles with ease, which contributes to an improvement of the operating performance of the binding machine.
