ABSTRACT:
A continuous strip of bundle tie material comprises a flat strip of thermoplastic having a generally channel shaped cross section. The upper surfaces of the sidewalls are provided with relatively fine ratchet teeth and the web of the strip has openings therein at regularly spaced intervals. In use, a section of the strip is passed around a bundle and one end is folded along the axis of the strip so that the fine ratchet teeth are directed outwardly and in opposite directions. The leading end is passed through an opening which is adjacent to the trailing end. The web material which is between the openings at the leading end forms coarse ratchet teeth for cooperation with the opening and the fine ratchet teeth cooperate with the opposed side edges of the opening. The fine ratchet teeth provide a fine or delicate adjustment so that the tie can be tightened on the bundle to the precise degree desired. The coarse ratchet teeth provide a safety feature to prevent removal of the tie from the bundle if the tie is subjected to extraordinary load conditions.
