ABSTRACT:
A method and apparatus for removing collars from compressed gas cylinders by applying a lateral force on first opposite sides of the collar, the force having a magnitude sufficient to collapse the side walls of the collar, in the direction of the applied force and to elongate the side walls of the collar in a direction perpendicular to the direction of the applied force and repeating the above step on second opposite sides of the collar displaced by approximately 90.degree. from the first sides, the second step freeing the collar from the cylinder neck allowing its easy removal.
