Abstract: 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.

Abstract: An apparatus for imprinting a sheet web includes two cylinders that rotate with a circumferential speed that corresponds to the speed of the web and which support the web over a specified angle region. Contactless printing heads are arranged side by side and at a distance to the circumferential surface of the associated cylinder and positioned transverse to the rotational direction of the associated cylinder. The printing heads each have a face oriented tangential to the associated cylinder and a center line that is essentially radial to the circumferential surface of the associated cylinder. A guiding device includes first and second guide devices associated with the respective cylinders to guide the web. Each guide device includes at least one pressure roller that fits against the surface of the associated cylinder and an element arranged to pull the web tangentially from the circumferential surface of the associated cylinder along a tangential path section.

Abstract: 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.
