Abstract
In the manufacture of a book, the book consisting of a cover and an inner book, the book cover is permanently shaped by the formation of folds in the articulation region thereof prior to being joined to the inner book. In the course of forming the folds in the cover, the covering material thereof is caused to undergo plastic flow and to be shaped so that beneficial stresses are created in the fold defining regions. The back of the cover may also be permanently shaped substantially simultaneously with the formation of the folds.
Claims20
In a process for the manufacture of a book, the book consisting of an inner book which is cased into a book cover, the inner book having a spine region and the book cover including spaced cover boards with facing oppositely disposed side surfaces and a back insert located between and displaced from said side surfaces, the book cover also including a deformable covering material which extends over the cover boards and back insert, the covering material being provided with folds which define articulation regions in registration with the spaces between the cover boards and back insert, the improvement comprising:
- forming inherently stable folds in the covering material under the action of heat before casing-in of the inner book into the book cover.
In apparatus for the manufacture of a book, the apparatus including a casing-in station for mating book covers with previously formed inner books, the book covers being comprised of spacially displaced cover boards and a back insert disposed therebetween and spaced therefrom, the spacing between the back insert and the cover boards defining a pair of generally parallel gaps, said gaps being bridged by a deformable covering material which extends over the back insert and at least partly over the cover boards, the cover boards having respective facing side surfaces which define first sides of the gaps, the covers being premanufactured in flat form whereby the faces of the cover boards which are contacted by the covering material define a plane, the improvement comprising:
- apparatus for forming folds in the covering material of a flat book cover where the covering material bridges the back insert defined gaps, said fold-forming apparatus being installed in the in-feed region through which the covers are delivered to the casing-in station, said fold-forming apparatus including movable heated fold-shaping rails and means for causing said rails to move in a direction generally transverse to the plane defined by a flat book cover in which the folds are to be produced, said fold-shaping rails bending the covering material around the edges of the facing side surfaces of the cover boards whereby the covering material is permanently deformed and the covers are thus provided with stable folds prior to being mated with inner books;
- means for delivering flat book covers to said fold-forming apparatus;
- and
- means for transporting shaped book covers from said fold-forming apparatus to said casing-in station.
