A yarnless broached finish runs a little differently in the initial process than with a sewn finish. When yarnless broached the hangovers are not bound with thread. Just before glueing the hangovers, a small part of the back is milled. This creates a certain relief in the back of the book where the glue must run between it. That’s how the hangovers get attached to the cover. After fixing the cover, the products go the same way as the sewn or the PUR products. To the cutter that cuts the books clean.
