There is described a sheet inspection system for a sheet-fed recto-verso printing press of the type comprising two printing cylinders () for carrying out simultaneous recto-verso printing of the sheets, said sheet inspection system comprising at least a first inspection device () for taking an image of a first side of the printed sheets. The first inspection device () comprises a first line image sensor () for performing line-scanning image acquisition of the first side of the printed sheets, and the first inspection device () is disposed in such a way that the first line image sensor visually acquires an image of a printed sheet while the said printed sheet is still adhering onto the surface of a first one () of the two printing cylinders () of the printing press and immediately before the said printed sheet is transferred to a chain gripper system () of the printing press. Also described is a printing press equipped with the inspection system.

Inspection system for a sheet-fed recto-verso printing press

There is described a sheet inspection system for a sheet-fed recto-verso printing press of the type comprising two printing cylinders () for carrying out simultaneous recto-verso printing of the sheets, said sheet inspection system comprising at least one inspection device () for taking an image of one side of the printed sheets. The sheet inspection system comprises first and second transfer cylinders () interposed between a first () of the two printing cylinders () and a chain gripper system () of the printing press, printed sheets being transferred successively from the first printing cylinder () to the first transfer cylinder (), to the second transfer cylinder (), and to the chain gripper system (). The inspection device () comprises a line image sensor () for performing line-scanning image acquisition of the one side of the printed sheets, this line image sensor () visually acquiring an image of a printed sheet while the printed sheet is being transported on the first or second transfer cylinder ().

The present invention relates to a device for placing and removing a doctor blade in a printing screen cylinder mounted on a printing machine having a support mounted on the frame of the machine in the continuation of the cylinder, and a track mounted on the support and designed to allow a slider to move parallel only to the axis of the cylinder between a first limit position situated outside of the cylinder and a second limit position situated inside the cylinder facing the working position of the doctor blade.

Disclosed is a clamping device () for fastening a plate () to the periphery of a cylinder (). Said clamping device () comprises a first clamping element (), a pivotally mounted second clamping element (), a spring part (), and a bracing element that is embodied as a pivotable spindle () and is movable between a clamping position in which the bracing element maintains the plate in a clamped state between the clamping elements and a released position in which the clamping elements release the plate. The spindle () is mounted in a groove so as to be displaceable, is fixed in an intermediate space between the spring part () and the second clamping element (), and is pressed against the second clamping element by means of the spring part in the clamping position.
