The invention relates to a system for processing liquid and/or solid compounds, comprising a vessel () and a holding device () for the vessel (), the holding device () comprising a stop () against which the vessel () rests after being inserted into the holding device () and a supply unit () opposite the stop (), the supply unit () comprising a closing element (), which can be set to a first and a second position, wherein in the first position of the closing element () the vessel () can be inserted into the holding device () and in the second position of the closing element () the vessel () inserted into the holding device () is pressed against the stop () by the closing element ().

System for processing liquid and/or solid compounds

The invention relates to a device, stacked plate reactor and to a method for investigating chemical processes to be carried out simultaneously or almost at the same time on a large number of functional element variations of the process parameters.

Device and method for investigating chemical processes

A method is provided for controlling the subsequent treatment of a workpiece that has previously been manufactured in an additive manufacturing process and has had marks formed thereon during the additive manufacturing process. The marks are used to control the application or ablation of material in the subsequent treatment of the workpiece.

Method for providing codes on components during a 3D manufacturing process

A print bar for inkjet printing includes print heads disposed in a row, adjustment devices for adjusting the print heads relative to one another in which each of the adjustment devices includes at least one screw and at least one shaft for rotating the at least one screw, and a compensation coupling interconnecting the screw and the shaft. The compensation coupling includes a first coupling half and a second coupling half configured to fit together under elastic deformation. The first coupling half includes spring claws having a first pitch and the first coupling half is disposed on the shaft. The second coupling half including a toothing having a second pitch and the second coupling half is disposed on the screw. The first and second pitches differ from one another.

A device for adjusting print heads, in particular inkjet print heads of an inkjet printing machine, on a print bar includes motors disposed in a row and supported for joint movement. Every motor carries a motor gearwheel and every motor gearwheel is successively engageable with at least two respective adjustment gearwheels.

Print head adjustment device

A printing device includes an ink jet print head having individually controllable nozzles for jetting ink drops. An ink line connected to a chamber has a feed and/or return line for the print head. The print head, ink line and chamber move jointly relative to printing material. The ink line is part of a circulation ink supply system for the print head. A mass element associated with the chamber has a position and/or shape relative to the chamber changing as a function of the joint movement so that the chamber volume is a function of the position and/or shape of the mass element to compensate for pressure fluctuations and/or movements of the ink and avoid problems in the ink supply system for a print head in industrial, high-performance ink jet printing and in cooperation with circulation ink supply systems conveying large volumes of ink.

Device for printing ink onto printing material

A print bar for inkjet printing includes a crossbar carrier, a row of head mounts carried by the crossbar carrier, and print heads held by the head mounts. Every head mount has lateral guide profiles for linearly guiding the head mounts. The guide profiles of respective adjacent or neighboring head mounts engage in one another.

A mounting device for a print head and a printing system allows print heads to be easily changed and easily and reliably adjusted. The mounting device includes a rigid mount and a frame for receiving a print head. The frame is releasably fixed to the rigid mount and includes an adjustment device for adjusting the print head relative to the rigid mount. The adjustment device of the frame includes two solid body joints and two actuators for adjusting the print head in two degrees of freedom, namely in a sliding movement along the rigid mount and a rotary movement about the vertical axis.

A sheet-transporting element includes suction openings for holding print sheets, longitudinal sliders including air passages, and transverse sliders including air passages. The longitudinal sliders and the transverse sliders are disposed in a cross-wise configuration and are movable into different positions corresponding to various sheet formats in the positions blocking selected ones of the suction openings.

A digital printing machine includes a printing material transport device, an inkjet print head having a nozzle plate, and a capping element. The inkjet print head is adjustable into a first print head position relative to the capping element and the capping element is adjustable into a capping position relative to the inkjet print head. The capping element temporarily covers the nozzle plate when the inkjet print head is in the first print head position and the capping element is simultaneously in the capping position.

Digital printing machine

A digital printing machine includes a printing bar for inkjet printing. The printing bar is mounted to be movable into a working position and into a retracted position. An adjustable roll and a spring-mounted roll form a first assembly and are disposed opposite one another. A rail forms a second assembly and is located between the adjustable roll and the spring-mounted roll when the printing bar is in the working position and is not located between the adjustable roll and the spring-mounted roll when the printing bar is in the retracted position. One of the two assemblies is disposed on the printing bar and the other of the two assemblies is separate from the printing bar.

A method for avoiding collisions in a digital inkjet printing machine, a method and a device for actuator-based lifting movement of inkjet heads. A sensor/camera monitors the sheets as they travel towards the inkjet heads. In order to avoid collisions, the inkjet heads are raised and lowered again individually and in an oscillation-optimized manner when a defective sheet is detected. The machine does not need to be stopped in the event of defective sheets. Advantageously, rejects can thus be reduced and the performance of the machine can be exploited better.

Method for avoiding collisions, for adapting a spacing and for actuator-based lifting movement in an inkjet printing machine

A method for controlling the temperature of a sheet in a printing machine includes measuring initial temperatures in zones on the sheet. Segments of an emitter are actuated in different ways as a function of the measured initial temperatures for irradiating cooler zones to a greater extent and warmer zones to a lesser extent or not at all. A common final temperature or at least a homogenization of the temperature is therefore achieved in the zones.

A device for feeding sheets to a digital sheet-processing machine includes a feed drum for transporting the sheets to the printing machine. At least two transport paths are provided to convey the sheets to be processed to the feed cylinder in at least two different positions from where the sheets are taken over by a gripper device of the feed cylinder and accelerated to processing speed. A digital sheet-fed printing machine having the device is also provided.

A method and an apparatus for holding down a sheet on a feed table of a sheet-processing machine include a lowerable smoothing bar which can be driven according to a speed profile in time with the sheet-processing machine, which results in a targeted deflection of the smoothing bar. The deflection is preserved for the purpose of smoothing the sheet from the middle to the side.
