Bundling of objects using a harnessing device with a locking head and a strap with teeth having a surface with a profile that is controlled by stretching so that if the teeth have an initial profile formed by rectilinear segments, the stretching converts the rectilinear segments to, for example, curved segments. The locking head contains a pawl or tang that engages the teeth of the strap by wedging. One or more wedging teeth are desirably located on the locking tang as well. A further tooth to promote locking is desirably included in the locking head. The strap is advantageously molded of stretch reorientable material which is subsequently stretched to control the profile of the teeth which are engaged by the locking tang and head. The teeth are spaced on the strap to permit use of the teeth near the head for the harnessing of small bundles. The pawl is provided with specified pivot points for both the insertion and loading of the strap in the head. |
