Stand der TechnikState of the art

Insbesondere der Einbau resp. das Auswechseln eines Verformungswerkzeuges in einer Verformungsvorrichtung bedarf eines respektablen Zeitaufwandes.Set-up times account for a relatively high proportion of production time for hardcover books. Even setting up a hanger is affected. In particular, the installation resp. the replacement of a deformation tool in a deformation device requires a respectable amount of time.

The deformation saddle 5 has two laterally downwardly directed saddle blades 9, 10, which lift the Buchdeckerücken 2 in the deformation of the flat lying position, so that it receives a curve through which hinged to the Buchdeckerücken 2 book cover 11, 12 of the book cover 3 are pulled inward from the initial positioning. To support the deformation, the folding form strips or folding rails 7, 8 can be designed to be heatable. The saddle blades 9, 10 of the deformation saddle 5 are adjustable resp. made adjustable, so that the latter can be used for each book thickness or book cover. For this purpose, the saddle leaves 9, 10 each have a variable rounded resp. curved surface that give a regular shape of Buchdeckerückens 2 when rounding. For this purpose, the saddle blades 9, 10 are formed pivotable about an axis extending parallel to the extension of a book block back or Buchdeckerückens 2 axis, said pivot axis is preferably located above a book block intended for a book or the book cover stretched out. The saddle blades 9, 10 form a closed, largely smooth surface at least during the deformation, so that no marks can be formed on the book cover back 2 when deformed. The folds or hinges of a book cover 3 forming, downwardly directed ends of the saddle blades 9,10 are jointly-about in the horizontal direction-against each other and movable from each driven, so that the deformation saddle 5, as in Fig. 2 shown for maximum book thickness at maximum rounding or as in Fig. 1 recognizable, set for a minimum book thickness with minimal rounding of the book cover back 2 or. can be adjusted.
