Nachdem ein letztes Druckprodukt einer Auflage den Klebebinder verlassen hat, erfolgt die Umstellung auf das nächste Druckprodukt. Dazu werden im Stillstand der Transportvorrichtung des Klebebinders sowohl auf die Formate (Höhe, Breite, Dicke) der nächsten Druckprodukte bezogene als auch formatunabhängige Stellgrößen in den Bearbeitungsstationen des Klebebinders verändert. Zudem können auch Führungen und Fördermittel der Transportvorrichtung auf die neuen Abmessungen der Druckprodukte eingestellt werden.After a last printed product of a run has left the perfect binder, the changeover to the next printed product takes place. For this purpose, both the formats (height, width, thickness) of the next printed products as well as format-independent manipulated variables in the processing stations of the perfect binder are changed at standstill of the transport device of Klebebinders. In addition, guides and conveying means of the transport device can be adjusted to the new dimensions of the printed products.

Eine solche Bauform führt zu einer kostengünstigeren Lösung, bei der eine Anpassung und/oder Optimierung des Transportkanals durch Austausch einzelner Blattfedern erfolgen kann.In a further embodiment of the invention, the individually spring-loaded pressure elements are designed as leaf springs. Such a design leads to a more cost-effective solution, in which an adaptation and / or optimization of the transport channel can be done by replacing individual leaf springs.
In einer weiteren Ausgestaltung der Erfindung ist oberhalb des Kanalbodens eine etwa parallel zur feststehenden Kanalwand ausgerichtete und von dieser beabstandeten Stabilisierleiste für die Buchblocks angeordnet. Eine solche Stabilisierleiste kann vorteilhaft ein seitliches Wegrutschen des Buchblocks im unteren Bereich des Transportkanals verhindern.In a further embodiment of the invention, an approximately parallel to the fixed channel wall aligned and spaced therefrom stabilizing strip for the book block is arranged above the channel bottom. Such a stabilizer bar can advantageously prevent a lateral slipping of the book block in the lower region of the transport channel.
In einer weiteren Ausgestaltung der Erfindung weist die Stabilisierleiste eine zur feststehenden Kanalwand ausgerichtete Fläche auf, welche in einem spitzen Winkel zum Kanalboden angeordnet ist. Eine solche Bauform der Stabilisierleiste kann ein seitliches Wegrutschen des Buchblocks noch sicherer verhindern.In a further embodiment of the invention, the stabilizer bar has a surface which is aligned with the stationary channel wall and which is at an acute angle is arranged to the channel bottom. Such a design of the stabilizer bar can still prevent laterally slipping of the book block.
