An apparatus and method are disclosed for forming a loop of flexible binding about objects positioned seriatim in an object receiving station. The apparatus includes a chain loop driven around the object receiving station. While a previously bound first object is in the receiving station, the chain is driven in one direction to move carrier rollers on the chain so as to pull the trailing portion of a binding through a major portion of the locus of a closed path around the receiving station while the lead end of the binding is held adjacent the receiving station. Spaced portions of the binding are guided from the interior of the path around the receiving station to maintain the binding in the configuration spaced outwardly of the receiving station. Subsequently, the first bound object is removed from the receiving station and a second object is positioned therein. The guiding of the interior of the binding around the receiving station is terminated so as to permit the binding to contact the second object while further pulling the trailing portion of the binding to complete the closed path and then form a tensioned loop about the second object.

Method and apparatus for pre-draping an object receiving station with

A gritless seal, a method for making the seal, and a method for forming a joint with the seal between overlapped ligature segments is provided. The inner gripping layer is brittle and has a hardness greater than that of the outer, ductile layer. In forming the joint, the seal is disposed about the overlapped ligature segments and is folded, squeezed, and/or crimped about the segments under pressure sufficient to deform the outer, ductile layer and produce fracture cracks in the inner gripping layer which present sharp edges to engage and hold the surfaces of the overlapping ligature segments. The interior of the sheet steel seal is case hardened by known cyaniding techniques.
