Abstract: In a binding machine for binding bundles of elongate articles, a switchover device for switching between a one-loop mode and a two-loop mode is provided. The switchover device is moved fore and aft relative to the twisting head of the binding machine so as to place the switchover device into a first position and a second position. In the first position, a binding wire is guided through a guide way into first and second annular passages therein, thereby making two loops around the elongate articles. In the second position, the binding wire is guided through the guide way into only the first annular passage therein, thereby making a single loop around the elongate articles.

Abstract: In a chamfering machine wherein a round bar material is longitudinally conveyed in the lengthwise direction thereof and is brought into contact with a grind stone for chamfering to chamfer an end surface of the round bar material and the round bar material is laterally conveyed in a direction orthogonal to the lengthwise direction thereof, a chamfering area including a conveying device for longitudinally conveying the round bar material, the grind stone for chamfering and a laterally conveying device is generally upwardly sloped.
