Folding Bellows Corners
By Karl Petersen

A recent radio news article on the Christian Science Monitor service noted that Nathan Kane, an MIT grad student, had recently won a prize for inventiveness for describing mathematically the optimum angles to fold bellows corners. This included the descriptions of several apparently new styles of corners, none of which were evident after considerable research into the patent office records or the ideas of accordions, cameras, etc.

I recall discussions on the design of pneumatic folds noting the various practical bellows corners folds, but none of these is technically elegant or truly simple. What have I missed??

What details have *you* seen that are out of the ordinary and, perhaps, of some specific advantage?

You can be sure I will communicate this with Nathan Kane (or you can cc: him) who enthusiastically welcomes news of old art in his research and development, and hopes that his developments will benefit us all.
