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 angle of abutment of the wire with respect to the wire receiving surface is made adjustable. As the front end portion of the wire is bent while abutting against the wire receiving surface, the remaining portion of the wire is also bent; that is, the wire is continuously bent, thus forming a wire loop. 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.

Abstract: Apparatus for wire wrapping or tying is disclosed, wherein an inner sleeve is telescopically positioned within an outer sleeve, each of which is provided with a handle for imparting relative rotational movement. The wire tie apparatus is adapted to receive wire which is wrapped an object to be tied. The wire passes through the outer sleeve then through the inner sleeve.
