Wide aperture wire tracking for baling machine

A guide track for a strap with which to bind a bale of bulk material. The guide track includes a convex portion and a restraining portion. Two lateral guide track halves are biased together. On their internal faces the guide track section halves have channels. The baling strap or baling wire is driven through the channels and guided around the material to be baled. The channels widen from a small diameter to a wide aperture at the receiving end of the guide track sections for receiving a lead end of a wire or strap that is propelled across a gap from a preceding guide track section.
