What kind of binding style is “Bradel Allemand”?

German binding is a patched cover that uses different materials for the spine and flat parts of the cover.
In April 1984, we started planning and selling all 10 volumes of “Mamebon Set” at the bookbinding studio Libre. Among them, “Ozaki Hoya Kusho” (Volume 9) incorporates the technique of tsugi cover, which was unfamiliar until then. That’s “German style”.
In fact, at that time, this patch cover did not have its own name. When I was thinking of a new name, I heard that in France this style of tailoring is called “Bradel Allemand” (German-style binding), so I decided to name it “German style”.
The German binding has a separate spine and flat cover, so you can use not only fabric, paper, leather, but also wood, metal, porcelain, and acrylic for the cover, so you can enjoy a variety of bindings.

The cover that wraps around the back and the cover on the front and back are made of different materials, which is the German style.

This is a special type of binding where the cover is recessed inward from the spine of the main body and has a step.
It is a bookbinding that requires technology in the bookbinding process.

The front and back, and the separately tailored cover are pasted solidly.

The cover is attached by hand using a brush, being careful not to shift it. Technology is needed there as well.

The German binding is basically the same as the codex binding, so it opens firmly 180 degrees parallel to the throat. It is also an eye-catching binding.

In addition, the combination of materials for the part that wraps the back and the front and back cover will change the impression completely, so you can elaborate various designs.
I think that the German binding is a bookbinding style that can demonstrate its design.
