Poetry in Motion... Vintage Spring Bending Machines
An amazing poetry of motion and sound... this all done long before computers and electronics took over. Each motion would be choreographed through a series of mechanical cams, gears and other linkages.
Of course, as one commenter pointed out, it does make for a long day for the operator.
I do believe these machines are more than half a century old, have been working near continuously for that long, and are ready keep pumping for another half century.
