Book shaped magazine unit - has flexible sheet cover with panels and formed enclosures

摘要

A book shaped cassette unit has an outer surface formed from a sheet of flexible material (2) that is bonded to two panels (4, 5) of cardboard that form the leaves of the unit. The edges of the flexible material are folded over the edges (6). The spine of the unit is formed by a separate strip of material (20). The folds are formed by creases (10, 11) in the flexible material. Bonded to the leaves are enclosure sections that stiffen the unit and form the storage volume. ADVANTAGE - Stable and simple construction.
