Bradel Following Denninger

A few years ago, the Stichting Handboekbinden posted the availability in sheets of Johann Denninger's De Bradelbinding (The Bradel Binding), also here. The New Bookbinder (1996) had published what I consider an abridged version with some history of the structure and something about this Bradel ... Like the article, this book started off with a lot of "according to" history, before going into the step-by-step instructions for what ends up as a hybrid historical/old school Pappband/Edelpappband, the latter so called because of the corner and head/tail reinforcements in parchment or leather, something that was first described in the literature around 1905. I describe the history of the Pappband structure, including a review of the literature and step-by-step instructions for the Ur-form in a 3-post series starting here.

But, back to Denninger ... I rarely follow instructions from a manual when binding it, but decided to in this case. The text is in Dutch, but I could get the gist of most from the illustration and my German/English Denglish. For those parts I couldn't figure out, I took screen grabs from the PDF available at the link above, then using Google Lens to translate the image. Then copy and paste into a Word ... document.

Making the endsheet section: this is a fairly standard historical
endsheet consisting of a double-folio text-like paper to which a
"decorative" folio is adhered resulting in a "made" endsheet(the schutblad). A 
single waste-sheet is hooked around this. You'll 
see why in later steps. 

The signatures were then rough cut. The top edge will get ploughed later

A template ensures that all the sewing holes line up ...

I sewed on three untwisted and frayed out cords, so like tapes, but ...

With the sewing done, the endsheet section was narrowly tipped-on
the adjacent signature, then the spine was glued up nice and square.

After rounding and backing to 45° at the shoulder with my "kashtoir",
I lined the spine with muslin between the sewing stations.

Then, I used my fray shield to clean up and untwist ... the strands
of the cords so that they were nice and clean ...

Next, I applied paste along the spine edge of the waste-sheet
and to the cord, neatly fanning them out and smoothing with a
folder so they weren't lumpy ... (Read image from right to left) 

When dry ..., I ploughed the top edge. Then, I applied a nice rolled
endband, I made mine of leather, and line the spine from end to end. 
 A simple one on, two off hollow was also suggested as an option,
but I went with just a simple paper lining as this is a very small volume.

Denninger then suggested a "gebrochener Rücken", scroll down here, the quintessential
hallmark of this style, or this little piece that was the width of the spine +
2x the slope of the shoulder. I had only seen this in connection with the
"Danish millimeter" binding, but gave it a try.

The edges were pared, then the over-long piece was adhered only
at the shoulder. Then, the boards were attached to the waste-sheet
adjacent to the shoulder. Glue should only go just beyond the fanned-out cords.

In keeping with the style, I made dainty little leather corners/tips.

Then I added the head and tail leather edging, when dry, I reduced
by paring the leather, and then sanded carefully so the transition
would be almost imperceptible.

Important, I also tore off the waste sheet so that it was nicely feathered 
out, and then sanded it so that it was all smooth. That way, the fanned-out
cords don't show through under the pastedown.

The same was done with the corners. They will be "invisible" 
when the cover is viewed board-on, and almost invisible on
the turn-ins.

Here, head [and tail] after covering.
After covering and making the turn-ins, I trimmed out the verso
of the board, so it was all neat and tidy.

And the corners from the inside showing the turn-in.

Finally, the overall. I made the oil-marbled paper in 2019. It was my
introduction to marbling in 1984, and 2019 was the first time in over
30 years ... The title is a laser printed recessed label with an edge,
something I learned from Bill Minter when I worked for him a
l.o.n.g. time ago. I describe how to here.

All-in-all, an interesting exercise and fun excuse to get back into binding after an extended absence.

This also ties in well with something I'm working on regarding the evolution of the Pappband/Bradel into the Edelppband, and now this thing called a Sandgren Binding. Nomenclature is important, but gets VERY messy with multiple languages and "creation myths".
