Thread Stitching / Open Thread Stitching

Thread stitching:

In the case of thread stitching, the signatures are folded and then sewn in layers into a booklet using bookbinders' twine. Finally, a layer of glue is applied to the spine and sealed with spine-binding tape.
For thread stitching for a K-BOOK it is important that at least one double-page fits contiguously onto a sheet. Thread stitching can therefore only be used up to a 22 x 31 cm format.

Special: Open thread stitching: Here the back of the book block remains open (no tape) and is glued only sparsely. The threads remain visible. This binding has a special charm and is often combined with the stiff soft cover type of binding.
