Abstract: An apparatus and a method for obtaining image information of an image original, such as a photographic negative, are disclosed. Light for exposing the image original (5) is emitted by a light source (10). Light that has been used to expose the image original (5) is subsequently detected by a light detector (28-30). In this case, obtaining the image information of the image original (5) is controlled by a control unit (31). The control unit (31) determines a certain point in time (T2-T4, T8-T10) corresponding to a parameter that has been determined earlier and that is specific to the image original (5). The light detector (28-30) is triggered at certain points in time (T2-T4, T8-T10) by the control unit (31) for obtaining the image information of the image original (5).

Abstract: The invention relates to a device for exposing a digital image onto light-sensitive material. Prior to exposure, the digital image is split into n partial digital images (n≧2) whose data is passed on to a control unit. According to the data, this unit controls n reflective light modulators that can be controlled pixel by pixel such that n partial images are generated at these light modulators that are illuminated by an illumination unit. The partial images are reproduced onto the light-sensitive material using an objective. In order to join the partial images into a total image, a prism or beam splitter complex is designed and arranged between the illumination unit, light modulators and reproducing objective such that both the illumination and the reproducing beam paths pass through it.

Abstract: The invention relates to a device for cutting off and conveying strips, for a machine. The device is used for producing a continuous web, especially of paper or card, for a threading strip, and has a knife. Finally the device is characterized in that it has it least one (preferably driven) guiding roll (27) which can be brought into engagement with the threading strip (27).

Abstract: Apparatus and process for separating and transferring a leader strip to be threaded into a machine for at least one of producing and treating a material web. The apparatus includes a separating device positioned to perform a separation process, a transfer device positioned to transfer the leader strip to a subsequent device of the machine after the separation process, and a common plate positioned to guide the transfer strip prior to the separation process. The transfer device is positioned upstream, relative to a strip travel direction, from the separating device. The process includes guiding a transfer strip over a common plate, separating the transfer strip with a separating device, and transferring the transfer strip to a subsequent device of the machine after the separating with a transfer device. The transfer device is positioned upstream, relative to a strip travel direction, from the separating device.

Abstract: Suction device and process for at least one of conditioning and drainage of an endless felt. The device includes a housing having at least one vacuum chamber, and a plurality of suction slits located on a suction surface of the housing that is adapted to face the endless felt. The plurality of suction slits are oriented to extend at least one of in and obliquely to a travel direction of the endless felt. The process includes guiding the endless belt over a suction surface of a vacuum chamber, and suctioning a surface of the endless belt with a plurality of suction slits located in the suction surface of the vacuum chamber. The plurality of suction slits extend in a direction that is at least one of in and oblique to a belt travel direction.
