A one-piece molded thermoplastic cable tie for forming a plurality of elongate objects into a bundle of generally circular cross-section and for compressively holding a pair of objects in engagement. The tie includes an elongate strap including elongate side rails joined by a thin web with the rails and web substantially symmetrical about a first plane intersecting the rails and web and also substantially symmetrical about a second plane normal to the first and intersecting only the web. A plurality of spaced teeth are disposed on one surface of the web. Cable Ties with various lengths are available from TotalFixings.co.uk in either Black or White Nylon.
This invention relates to bundling apparatus and
more specifically to a one-piece molded thermoplastic
cable tie for forming a plurality of objects into a bundle.
Commercially available one-piece plastic cable ties
have excellent performance characteristics when used
in moderate to warm temperature environments; how
ever, they have limitations when used in extreme low
temperature. This occurs because the strap becomes
increasingly brittle with decreasing temperature. Additionally, the presence of teeth on one surface of the
strap, as with any discontinuity, has a "notch effect" in
that the teeth tend to foster localized stress concentrations at their relatively sharp junctures with the web of
the strap when the strap is bent. While such ties can be
used at low temperature if handled carefully, severe
flexure or shock could result in strap breakage.
