I have a question about a wire stitching machine. I have recently owned a historic “Universal” wire stitching machine from Gebr. Brehmer and it doesn’t staple. I took apart the stapling head, which is at the bottom of this machine, and it seems to me that the punch (i don’t know if it is a correct name, in german we say Durchtreiber) is bent. I never work with this machine, so I wanted to ask whether someone has worked with such a machine and knows what the punch should look like, has documentation for it or, even better, happens to have an “unnecessary” punch. I am thankful for every hint.
