I worked for a while in one of the biggest abattoirs in the world, mainly in the sheep-gutting area. The plant was a maze of conveyors like a model railway layout from hell, and the tripe went along a little line of its own against the wall and through curbing corridors from and to who knows where. They put about 20 cleaned tripes on every hook, and they formed a man-sized pear-shaped blob that wobbled as it trundled along. It was as if we we re butchering triffids.
