An apparatus for producing book blocks includes a station to dispense a sheet web that moves in longitudinal direction and can be imprinted. A printing station has two cylinders that rotate with a circumferential speed corresponding to the movement speed of the web and function to support in a contacting manner the web with their circumferential surfaces over a specified angle. Contactless printing heads are assigned to each cylinder, arranged at a distance to the circumferential surface of the associated cylinder, and positioned side by side and at least essentially transverse to the circumferential and rotational direction of the associated cylinder. The printing head faces are oriented substantially tangential to the associated cylinder and the center lines of the printing heads are oriented to project substantially radially to the circumferential surface of the associated cylinder. The web is guided so that when it rests on one cylinder, one side of the web is imprinted and when it rests on the other cylinder, the other side of the web is imprinted. A desired web tension is created in the printing station. A cutting station is arranged downstream of the printing station to cut the printed web in longitudinal and transverse directions to form sheets having a predetermined height and width. An overlapping station arranges the cut sheets into an overlapping formation. A station collects the sheets to produce stacks that form book blocks.

Apparatus and method for producing book blocks

A support for a material web for use with a longitudinal cutting device for cutting the material web, includes a support shaft having an axis of rotation. At least one bearing mechanism positions the at least one support shaft, wherein the at least one bearing mechanism has an axis of rotation outside of the axis of rotation of the support shaft.
