There is provided a system for handling and creasing cardboard, as well as sub-systems of said system. Other embodiments are also disclosed.

Cardboard-handling system and method

A cardboard-handling system with a rule-die associated to a first drum and a counter die associated to a second drum for pre-treating cardboards. A cardboard-alignmentor on a first side of the rule-die and counter-die aligns and conveys a cardboard together with one or more synchronized-cardboard transferors toward a side-gripper conveyor. The side-gripper conveyor transfers the cardboard toward and through the rule-die and counter-die drums for pre-treatment of the cardboard. Next the side-gripper conveyor conveys the cardboard toward and through a laser-treatment module to be further pre-treated. The side gripper conveyor movement is synchronized with a laser-treatment module for which a base with a plurality of protruding elements has moving capabilities and is synchronized with the side-gripper conveyor (via a timing belt for example).

A device for storing, transporting and feeding a roll-forming web of printing material for a machine for processing the material. The device has a housing that surrounds and includes a receptacle for the roll. The housing is manipulatable in a manner analogous to a pallet, and is disposed for receiving and surrounding the roll, from which the web of printing material is unwindable.

Apparatus for storing, transporting and delivering roll-formed flat printing material for a machine processing such material

Method for form-processing paper in a printing press by at least one processing tool and a computer includes converting digital data representing desired processing geometries into signals in the computer, and controlling the at least one processing tool with the signals so as to obtain the processing geometries: and apparatus for performing the method.

Apparatus for form-processing paper in a printing press

A circuit arrangement for a reversible image build-up of a surface matrix of a printing form for a printing machine, wherein the surface matrix has regions which are activatable and de-activatable by repeated triggering, includes a respective electrical circuit operatively associated with every region of the surface matrix activatable and de-activatable by the repeated triggering, at least one threshold value switch connected in each of the electrical circuits and having a switching state variable by the triggering for respectively activating and de-activating the region operatively associated therewith.

Method for applying spacing material to a sheet printed by a printing press includes providing spacing material which is solid at least at ambient temperature, spotwise applying individual spacing material particles formed from the spacing material onto a surface of the sheet, and fixing the applied spacing material particles to the sheet; and a printing-press device for performing the method.

Method for applying spacing material to a printed sheet of paper, and a

Ink-jet device for producing an image on a recording medium includes a droplet-producing device for ejecting droplets along a trajectory, and a droplet-controlling device for controlling the trajectory of the droplets, the droplet-controlling device being formed as a deflection surface, the deflection surface being disposed so that respective droplets impact thereon and rebound to continue the flight thereof, the respective droplets being splittable into at least two subdroplets as a function of selected parameters, and ink-jet process.

Ink-jet device and method of operation thereof

Apparatus for protecting the surface of freshly printed sheets which are deposited upon one another to form a sheet pile includes an applicator for applying to the respective sheets a separating-agent layer formed of solid particles of separating agent, the layer of separating agent being formed of a mixture including at least one degradable separating agent substance, an aqueous vehicle liquid, and at least one mixture component which degrades the separating agent substance upon simultaneous contact with the separating agent substance and the vehicle liquid.

Apparatus for protecting the surface of freshly printed sheets

Piezoelectric actuator having at least one piezoelectric element assigned to an electrode for applying a control voltage includes a hollow body having a volume filled with an incompressible liquid, an elastic membrane closing an opening formed in the hollow body, and a device for controlling the piezoelectric element so as to vary the volume of the hollow body during a deformation of the elastic membrane caused by the incompressible liquid.

Piezoelectric actuator

An adjusting device for providing a zonewise adjustment of the ink gap with respect to the ink-fountain roller in a printing press is manually adjustable via a respective adjusting screw, and has an additional device for performing a coarse adjustment in a relatively short period of time. A plurality of such devices can be disposed side by side along the ink-fountain roller for providing numerous ink zones along the ink-fountain roller to thereby substantially reduce adjustment time for setting up an ink profile.

Device for adjusting the supply of ink in the various ink zones of a

A printing machine for performing flat-bed printing having a printing form with hydrophobic and hydrophilic area thereon corresponding to an image to be printed, and a device for electrochemically converting, respective areas thereof for producing a printing copy from the hydrophobic into the hydrophilic state by means of a current-conduction arrangement, including a fluid applicator for applying a hydrophobic fluid full-surface to a surface of the printing form, and a control device for controlling the current-conduction arrangement for forming appropriate current paths and for electrochemically removing the hydrophobic fluid area-by-area in accordance with the hydrophilic areas required for the image to be printed; and a method of operation thereof.
