Also at the Berlin Tech Museum was a punch tape driven embroidery machine. The Tech Museum has a ton of industrial textile equipment as part of their permanent collection. The machines are completely mechincal, as far as I can tell no electricity is required.
Sadly I couln’t read the German placquard explaining more about it, and couldn’t find much info online. I got a snapshot of the name plate so I’d at least know what it was called.
If anyone knows more about these machines I’d love to hear it.
