Abstract: The invention relates to a method and a device for producing three-dimensional molded parts from a continuous sheet of a flat, plastically malleable fiber material via deep drawing with a stamp and an associated die, wherein the fiber material between the stamp and the die can be reshaped via a relative movement. The object of the instant invention is to offer a method and a device for producing three-dimensional molded parts in which the reshaping is done via deep drawing from a cut-to-size section in the continuous sheet and which leads to a high reshaping ratio. The problem is solved by connecting the round, rectangular, oval or irregular cut-to-size section for the molded part during the deep-drawing process to the continuous sheet of fiber material via at least one web and otherwise separating it from the continuous sheet via at least one stress-easing cut; a reshaping ratio, as the ratio of the diameter and the depth, of greater than 0.2 can be realized.

Abstract: A device for imaging a flat object, for example a paper sheet in a printing machine, includes a light source, preferably an LED row, a lens and an image sensor. An observation angle between the object plane and lens axis is flat, that is to say less than 45°. The light source illuminates the flat object in a first, near region with light of a first wavelength and illuminates the flat object in a second, far region with light of a second wavelength. The first wavelength is shorter than the second wavelength, preferably being blue and red spectral regions. The first region is disposed nearer the image sensor than the second region. The device permits the so-called chromatic aberration of the lens to be utilized to advantageously reduce the tilt angle of the image sensor required by the so-called Scheimpflug condition. A printing machine having the device is also provided.

Abstract: The invention pertains to a lubricant distributor for distributing lubricant to several lubricating points, with a cavity, in which a piston is arranged in a sealed and movable fashion. Several lubricant outlets, which are sealed relative to the cavity by the piston, lead into the cavity.

At least one channel is formed in the piston and makes it possible to produce a fluidic connection between the at least one inlet channel and one of the lubricant outlets depending on the position of the piston within the cavity. The invention furthermore pertains to a lubricating system that includes such a lubricant distributor and a lubricant pump that is connected to the lubricant inlet via a line.

Abstract: A method of activating a Multi-String inverter for photovoltaic generators (1a, 1b) of a photovoltaic plant (6), the Multi-String inverter incorporating on the input side a separate DC-DC converter (2a, 2b) for each generator string (photovoltaic generator) (1a, 1b) and each output of the DC-DC converters (2a, 2b) being connected in parallel and to an input of a DC-AC converter (3) and the DC-AC converter (3) being connected with an alternating current mains (4) for feeding into the mains aims at improving efficiency.

Abstract: Data records contain identification data and user data and are either contained in a highest grouping level or are directly subordinate to precisely one data record group. Each data record group is either contained in the highest grouping level or is directly subordinate to precisely one data record group. Each data record group is in this way either empty or contains at least one directly subordinate element, which is either a data record group or a data record. A selection criterion is specified to a computer by a user, whereupon the computer displays to the user via a display device a list of at least the elements contained in the highest grouping level. The list is sorted according to an ordering criterion independent of the selection criterion.

Abstract: An image is recorded of the edge of a moving object, in particular a sheet, in a machine processing printing material. The illumination is carried out with an illuminating device, and an image is recorded of at least one part of the edge with an image recording device. The use of the illuminating device and/or the image recording device is substantially synchronous with the movement of the object and substantially parallel to the direction of movement of the object. A preferred illuminating device has a row or array of light sources which in each case are switched on and off synchronously with the movement of the object. The constant shadow or shadow strip produced by the illumination moves with the object and ensures adequate contrast between the brightly illuminated object and the dark background, so that the object can be segmented reliably, at least in the region of the edge, and its position, orientation and movement can be determined.

Abstract: A method for controlling an operating process of a printing machine uses parameters of 3-D scenes taken with only one camera. A learning phase is performed in which the object in a non-moving state and its surroundings are illuminated from different directions by different fixed-location light sources, one after another. For each illumination scene, image signals reproducing the object and its surroundings are obtained with the image recording device. The image signals are processed and an unambiguous association between object edges and object shadows in relation to a light source in each case are determined and stored. In an operating phase, the moving object and its surroundings are illuminated simultaneously by a plurality of light sources, and, from the data stored in the learning phase and the image signals obtained continuously in the operating phase, the position of the object in space is determined.
