  • End-forming of corrugated metal foil wrap tubing
    Patent number: 6705148
    Abstract: A method and apparatus for forming the free end of a length of metal foil wrap corrugated tubing, in which a free end of the tubing is first crimped against a mandrel, then folded to extend radially inwardly, then folded further to extend axially inwardly within the inside diameter of the tubing end, and then compacted axially to bring the corrugations into facing abutment with each other and tighten the formed end of the tubing against unwrapping of the metal foil. The crimping operation involves closure of a plurality of jaws around the free end of the tubing and deforming the tubing end against a tapering surface on an internal mandrel. The tubing is then gripped between jaws that form a radially indented channel in the periphery of the tubing, both to enhance the clamping action of the jaws and to isolate the formed end of the tubing from the remainder of the tubing.
