Today we are replacing one of our bucket conveyers at work. This is basically a long rubber belt that has buckets bolted to it to move product. One of the parts we need to assmble this is a belt fastener, so we were checking our physical inventory to ensure we had enough and that they were the correct type. Now some of our inventory has sat on our shelves for a long time, this is one of those items. We opened the box and there was some product promotion literature in the top bearing the tag line: "CAUTION! Are you trying to join today's belting with yesterday's fastener?" With a bit of further examination the copyright date was 1977. It may be just a touch out of date.
