  • what happened to Rolamite?

    Remember Rolamite? http://www.rexresearch.com/wilkes/1wilkes.htm describes this invention. It seemed to have great promise, but few of its proposed applications made it to the marketplace.

    Has anybody ever incorporated Rolamite into a device?

    Bad things happen when the ribbon breaks. It overcomes a problem seldom seen. Bad things happen when the ribbon stretches. Compound bearings are well understood and available. Did I mention bad things happen with that ribbon? Imagine what would happen if somebody put a penny or FOD of any kind on the ribbon, frinstance. Probably why D9 Cats use segmented tracks instead of ribbon.

      that ribbon experiences a lot of bending when it is moved back and forth, especially the model with the polygons instead of spheres/cylinders. Are ball bearings really that bad!?!

        Several uses, primarily in switching, exist and multiple patents have been taken out (for example: Rolamite sensor: United States Patent 5178264 http://www.freepatentsonline.com/5178264.html). In fact there is an entire patent class for rolamite type switches (Electrical contacs - class 200, subclass 504).

        Don't know about other uses.
