The cam may include a body having an outer surface at a substantially constant diameter extending between a first end and a second end, a first path helically disposed inward from the outer surface, around the body in a first direction, wherein a first end of the first path is proximate the first end of the body, and a second path helically disposed inward from the outer surface, around the body in a second direction, wherein a first end of the second path is proximate the second end of the body.
Abstract: A method and apparatus described to stabilize and secure individual component items in an array during gas flushing and packaging, without obstructing or preventing the free flow of the gas-flush throughout the component. In accordance with the present invention, when the array has been composed, it is over-wrapped with a loop of thin, inexpensive, gas-permeable film applied under pressure or shrunk around the array, leaving two opposite faces of the array free of the over-wrapping loop.
