A method of operating an anilox printing unit (2) in which ink accumulates on and detaches from a feed blade (6) and, after detaching from the feed blade (6), forms ink accumulations (10) on a screen roller (3), and in which a gap (9) is formed between the screen roller (3) and a further roller (4) for the ink accumulations to pass through the gap without contacting the further roller (4). The method includes forming the gap (9) by displacing the axis of the further roller (4) and evening out the ink accumulations (10) on the screen roller (3) to such an extent that the ink accumulations (10) that have been evened out pass the gap (9) without contacting the further roller (4). A smoothing roller (11), for example, may be used to even out the ink accumulations (10).

The invention relates to a method of controlling a powder sprayer (10) having a fan jet nozzle configuration (13) in a printing press, includes controlling the fan jet nozzle configuration (13) as a function of operating parameters of the printing press. And when the output speed of a supportive-air fan jet (19) is changed, the output speed of a powdered-air core jets (20) of the fan jet nozzle configuration (13) is kept not change.

In a method for controlling the temperature of a press which has an applicator roller and a screen roller, the screen roller has its temperature controlled at different temperatures and the applicator roller has its temperature controlled at a constant temperature.

The present invention relates to a method for operating a printing machine in a print operating mode and another operating mode, for example a maintenance mode. In the print operating mode, bringing a vibrating roller periodically into contact with a first roller (5) of an inking unit (3), driving the first roller (5) rotationally by a first motor (11), driving a second roller (6) of the inking unit (3) rotationally by a second motor (12), transmitting no torque from the first motor (11) to the second roller (6) through a clutch (21) therebetween, and activating the first motor (11) by a control device (37) causing the first roller (5) to rotate at a rotational speed in a constant ratio to a rotational speed of the second roller (6). In the other operating mode, driving the first and second rollers (5, 6) rotationally by the first motor (11) and transmitting torque from the first motor (11) to the second roller (6) through the clutch (21).

An electrical appliance 1 such as a hand power tool is connected to a power supply unit 2 also known as a battery/power pack. The electric appliance is protected against overheating without necessitating abrupt stoppage of the operation of the electrical appliance. The invention includes determining a temperature or a variable which depends on the temperature of an element selected from the group consisting of a current supply unit connected with the electrical device, one or several components of the electrical device, and both, and when the determined temperature or a variable which depends on it exceeds a predetermined threshold, reducing power taken from the electrical device until the temperature or a variable which depends on it falls below the threshold or a lower threshold.

The claimed process for treating exhaust fumes (6) from an internal combustion engine (19) in at least two modules (3, 4, 5, 17) is designed in such a way that an exhaust fume stream can be at least in part deflected depending on a load state of the internal combustion engine (19) in such a way that at least parts of the exhaust fumes (6) flow through one or more modules (3, 4, 5, 17). The claimed process and the claimed device (1) make it possible to design and operate in an advantageous manner even the exhaust fume system of large-volume internal combustion engines (19), conversion and treatment of the exhaust fumes (6) being carried out in individual modules (5, 3, 4, 17) even in no-load operation, basically at very low exhaust fume mass flow rates. The individual modules (3, 4, 5, 17) can be adapted to various load levels of the internal combustion engine (19).

The invention relates to a sheet brake of a printing press, comprising braking bodies (14, 15) diverging in the sheet travel direction (7) for lateral tensioning of a printing material sheet (6). The braking bodies (14, 15) are driven in a circular motion at a non-uniform speed (VB).

A method for operating a cleaning apparatus, having a trough and a brush disposed in the trough, in a printing press, includes first, second and third steps. In the first step, a cylinder of the printing press is cleaned by the cleaning apparatus, with the brush bearing against the cylinder. In the second step, the brush is moved away from the cylinder, and a level of a liquid in the trough is changed, resulting in the liquid being brought into contact with the brush. In the third step, the brush is cleaned by the liquid in the trough. A printing press for carrying out the method is also provided.

The invention relates to a testing device (10) for testing screw spindles or screw systems, said testing device being provided for installing between an output of a screw spindle to be tested and a screwing location. The testing device has a torsion element (12) which is received in a main part (11) such that the torsion element is provided with a specified pretension and is used to apply a spring characteristic to a screw spindle torque curve, which is produced by a screw spindle to be tested, when the torque curve influences the torsion element (12). The spring characteristic is determined by two stop positions of the torsion element, and means are provided in order to analyze measured data which characterizes the torque curve of the screw spindle in that torque curve interpolation nodes which correspond to the stop positions and which determine the spring characteristic are used as a measure in order to evaluate a screw spindle behavior which deviates from the norm using the analyzed measured data and the spring characteristic impressed in the measured data.

The invention relates to a spindle drive (1) for a path-controlled adjusting device, which has at least the following components: a spindle shaft (3) having a worm gear drive (4); a spindle nut (5), which is translationally movable by means of the worm gear drive of the spindle shaft as a result of a torsion of the spindle shaft; a drive pinion (6) for driving the spindle shaft; a drive pawl (8), which is fastenable to a coupling cover (7), for path-controlled driving of the drive pawl; a receptacle (9) for the spindle shaft, which axially fastens the spindle shaft; and a transfer element (10) which is designed to transfer the translational movement of the spindle nut to an adjusting ring, which is rotatable about a rotation axis aligned crosswise to the spindle shaft, wherein the transfer element comprises a plate element (13), which is tiltable around the rotation axis and via which, in assembly, the transfer force from the spindle nut on the adjusting ring can be applied centrally on the spindle nut. The transfer element according to the invention ensures an always central force application into a spindle nut, thus preventing a blocking of the adjusting device.
