  • Method and apparatus for forming a tube
    Patent number: 4753098
    Abstract: A method and apparatus for forming tubes, rods and the like into a serpentine configuration. A plurality of guide rails are mounted on a supporting surface and carriage bars are slideable on the guide rails. A lazy tong linkage having bend forming members mounted thereon is slideably mounted on the carriage bars. A lazy tong linkage assembly is disposed on each side of a center line and expander mechanisms are provided for forcing the two spaced lazy tong linkages apart. Drive means connected to the carriage bars drives the lazy tong linkage to a collapsed position and this movement causes the bend forming members to form a straight tube or rod into a serpentine configuration.
