Research notes

This is a yarn-feed and tension device (bracket, gun head, roller frame, feed rollers) for automated gun-tufting machines, meant to stop yarn tangling. Its background cites CN207313899U, a synchronous yarn feeder for a gun-tufting carpet machine, which shows a cluster of 2017–2020 patents on robot gun-tufting. It is included as an example of that cluster, not because it is important on its own. Verified Oct 2026 by web search only. patents.google.com and Espacenet could not be opened from the sandbox, so I did not read the document itself. The title and filing date come from Google Patents snippets. Research note (Oct 2026): found through search results; the patent document itself wasn't opened. The Patent drawings job fetches the document from Google Patents; if drawings appear on this record, the number is confirmed.
