A clamping device for thin flexible printing plates where the device has a plurality of first narrow width plate clamps for clamping the leading edge of a plate, a plurality of second narrow width plate clamps for clamping the trailing edge of the plate, and where the first and second clamps form cooperating pairs of clamps arranged in side-by-side longitudinal assembly in a small shallow axially extending groove on the surface of a plate cylinder of a rotary printing machine. Compression springs are positioned between the clamps of each pair of clamps and a leaf spring blade is held in place on each one of the second clamps by one of the compression springs. A longitudinally extending shaft is provided for each of the plurality of first clamps and of second clamps for opening and closing all of the clamps simultaneously.

A mechanism for loading and unloading the design cylinder in a rotogravure press unit including support bearings mounted in a pivotally supported housing in the side frames of the unit so as to be self aligning with the shaft of the design cylinder for freely supporting therebetween the design cylinder. A pair of supporting members having bifurcated heads for cradling therebetween the design cylinder, are pivotally secured to a pair of cranks mounted for pivotal movement adjacent the inside surfaces of the side frames. Pivotal movement of the support arms and cranks is controlled by a mechanism for pivoting the support arms away from the press unit thereby lifting the design cylinder off its bearing and swinging it away from the press.

A newspaper-printing machine folder has two pairs of nipping rollers and one pair of folding rolls. The rollers of each pair are held against one another under the pressure force of a spring or the like elastic means. The setting of the position of the rollers is adjustable according to the thickness of the product to be folded. Additional pressure force balancing devices are provided on the rollers. Sensing elements are arranged for detecting of differences of the roller pressure, controlling the motive power-operated adjusting devices for resetting the roller position to the originally set force.

An ink fountain for a rotogravure press which is pivotally mounted and can be tilted down away from the printing cylinder for cleaning the fountain pan or changing the cylinder. A cover system for enclosing the cylinder when the pan is in its operative position and which will automatically cam off or lift away from the cylinder as the pan is lowered away from it. The cover system is hinged to the pan and can be swung away from the pan so as to uncover the pan and cylinder for easy cleaning and replacement.
