One-Part Hard Cover with Round Spine without Burned-In Joint

Bild

The cover of the Kösel Fullflex FD 401 consists of a cover which is glued onto one piece of cardboard and folded in on all four sides. The thickness of the wrap is determined by the cover material and is therefore thinner than the integral cover. The book block can be enclosed without a burned-in joint attached to the cover.

The 280 g/m2 used is soft and flexible.For larger and heavier books stiffer cardboard stock can be used. A combination of suitable cover material and cardboard stock can therefore be produced for any type of book.
The complete manufacturing process for Kösel's Fullflex FD 401 is done in-house which ensures short production times.
