FR 600

Brochure with Sprung Spine Technology

The sprung spine technology is generally only known in hardbacks. A similar effect can be achieved with the FR 600 binding method. The folded-in parts of the cover flaps extend almost up to the spine of the book block. The flaps are glued along a small area about 10 mm from the spine of the book block.

The gauzed or spine-glued block is only held by the special cover at the sides. Like all Kösel FR bindings the spine therefore remains free. The good opening behaviour due to the free spine is further enhanced by the long flaps that extend almost up to the spine of the book block.
