For a time, I worked as a doffer in an LA (Lower-Alabama) "cotton" mill...huge bales of cotton came in one one and massive rolls of heavy-duty cloth came out the other. If you search Google images for "doffer", you will see in those child-labor photos much of the very same equipment I used during the very early '80s (that is
1980s!) . What an unbelievably LOUD place...particularly the weaving room where the above thread shuttles were used!
Even then, the equipment was ancient - as were the buildings. The wooden floors in those buildings shook with the seemingly synchronized slamming back-n-forth of all those weaving machines' shuttles. Imagine a hundred or so of these machines pounding incessantly away at your sanity your entire shift...no escaping it, not even on your "break".
One night a few years after the mill had shut down, a careless copper scavenger's torch got away from him and those floors - soaked with almost a century of machine oil and grease - went up faster than any fat lighter wood I have ever seen! The huge mill burned to the ground in minutes; only random brick walls remained standing.
Sorry, did not mean to ramble nor hijack your thread. Yes, weaving loom shuttles for the weft threads. Brings back memories...if you couldn't tell.
Respectfully,
