摘要:
Devices for accomplishing the alignment of a covering applied to a cylinder in a printing machine include a detent and a roller element. The detent is situated in a mounting direction of the covering and is upstream of the roller element. The covering to be applied engages with the detent. In an alternative configuration, the roller can itself act as the detent. A method for aligning or for mounting the covering on the cylinder utilizes the detent or the roller element.
摘要:
A transmitter including: a sensor, which serves for registering a physical parameter (X) and transducing such into an electrical quantity; a signal pre-processor, which serves for converting the electrical quantity into a raw signal (R); a signal processor, which serves for converting the raw signal (R) into a measurement signal (M); an output stage, which serves for issuing an output signal corresponding to the measurement signal (M); and a monitoring unit, which in operation compares the output signal with an auxiliary signal (H) derived from the raw signal (R) and triggers a safety-directed adjustment of the output signal, when a difference between the output signal and the auxiliary signal (H) exceeds a predetermined limit.
摘要:
A transmission system including a shift mechanism for operating and controlling the transmission system. To automatically detect geometric characteristic values of the transmission system or of the shifting device a selector motor and a shift motor actuate a selector finger that is displaceably mounted in a selection-shift-passageway layout. Starting from an initial position whose coordinates within the selection-shift-passageway layout are unknown, the selector finger is displaced in the directions of shifting and in the directions of selection in order to detect paths of movement in the direction of selection or shifting. The selector finger is repeatedly displaced to establish the maximum paths of movement until the predetermined transmission geometric characteristic values are completely detected. Also disclosed are a control device for controlling a transmission system that includes a shift mechanism, and a method for controlling such a transmission system.

The contact pressure between an adjustably mounted first cylinder and a second cylinder in a printing machine, and particularly in a web-fed printing machine can be adjusted. An actuator is usable to force the first cylinder toward the second cylinder with an adjustable force. A fixing device is usable to fix the first cylinder in a desired position relative to the second cylinder.

A device is used to store blankets or dressings which are to be supplied to a cylinder of a printing machine. A plurality of such blankets or dressings, which are to be applied to the cylinder adjacent each other and axially spaced, are stored next to each other. These blankets or dressings are stored vertically above a supporting surface, in at least two vertically offset planes. The offset planes form a first storage position and the supporting surface forms a second storage position once at least one of the blankets or dressings has been stored in the different planes.
摘要:
A printing plate is prepared for the insertion of images by applying an ink accepting layer and an ink repelling layer to it. A developing fluid is sprayed onto the ink repelling layer by an ink jet printing group. The developing fluid is sprayed in the image to be printer and the ink repelling layer is etched or dissolved in the sprayed area. The etched or dissolved areas of the ink repelling layer are removed. The method is particularly adapted for use with a waterless printing plate having an ink repelling layer of silicon.
摘要:
A device for fixing a flexible plate having angled or beveled suspension edges to a cylinder utilizes a plurality of fastening elements located in a cylinder groove situated radially inwardly of a fastening slit. The fastening elements are engageable with the suspension legs under the influence of spring forces. Separate fastening elements can be used to engage the leading plate suspension leg depending on the direction of rotation of the cylinder.
摘要:
A method of regulating the position of a clutch actuator in a vehicle employs the concept of adapting the servo-loop parameters of a position controller of the clutch to different operating conditions of the vehicle, as well as the concept of applying and continuously adapting a bias current of the actuator motor in order to avoid or minimize the incidence of a hunting or after-regulation behavior of the control loop and to thereby minimize the energy consumption of the actuator motor.
