Abstract: An ink jet printing device (1) for printing multicolored images has an essentially horizontally extending conveyor mechanism (2) for moving items to be printed (3) lying on it in a forward feed direction (4), and a print head arrangement (5) disposed above the conveyor mechanism (2) which is disposed stationary relative to the conveyor mechanism (2) during the printing process. The print head arrangement (5) is made up of several print heads (6) each with several nozzles disposed in a nozzle row (26), and the nozzle rows (22) have a printing range width (24) as measured perpendicular to the forward feed direction (4) which forms a total printing range width (27) of the print head arrangement (5) corresponding to the number of print heads (6). The print head arrangement (5) is disposed so that it can be displaced vertically on a guide (10) and a nozzle rinsing device (14) is provided which can be positioned underneath the print head arrangement (5) as and when necessary.

Abstract: According to a method for making disposable diapers/adult incontinence pads, a diaper/incontinence pad is made whose pad is in three layers one on top of another; two outer layers of the pad consist of absorbent material and are positioned on opposite sides of an intermediate layer, which consists of a mixture of the absorbent material forming the two external layers and shredded material obtained by shredding faulty diapers/incontinence pads rejected from the diaper/incontinence pad production line.

Abstract: The invention relates to an ink jet printer (10) for different media with a print head unit (14) having at least one print head (16) for applying print to the medium (101) and a printing table (110) for positioning and/or guiding the medium (101) to be printed, and a displacement mechanism for varying a distance between the print head unit (14) and the medium (101) in a direction perpendicular to the guide surface as well as a control system (120).

Abstract: A loading and unloading device (10) for reeled material (34) is designed in the form of a carriage, which can be moved by a single operator, and has a bearing (16) for each of the two lateral ends of a reel (34), it being possible to raise and lower the bearings, which can be locked at least in the raised position.

Abstract: A gripping apparatus for reel material includes a reel support, a first clamping device and a second clamping device as well as a cutting device arranged between the clamping devices. The first clamping device is spring-mounted along two non-parallel axes so that the paper web can be evenly clamped and cut transversely to the web direction without twisting and formation of undulations.

Abstract: A take-up apparatus for reel material of an image exposing device has a driven winding drum and a sensor provided to control the drive of the winding drum. The sensor detects the position of the reel material ahead of the winding drum. In this case, the drive of the winding drum is controlled in such a manner that the reel material forms a bulge (A) ahead of the winding drum with a substantially constant curvature.

Abstract: A diaphragm adjusting arrangement in an enlarging appartus having several lenses with an adjustable diaphragm includes a motor drive for the common adjustment of the diaphragms of all lenses and a device for detecting the adjusting path. By means of the comparison of the actual position of the diaphragms with a given desired position in a control circuit, a control signal is generated for the motor drive to move the diaphragms into the given position.

Abstract: This invention relates to a photographic color enlarging apparatus having a measuring device for determining the density of a test copy which, by means of the enlarging apparatus, is exposed from a reference original selected for the test-adjusting of the apparatus. Light-guiding means (15) guide light from the copying-light source of the enlarging apparatus into a measuring level outside the path of the copying rays which receives the test copies to be measured, and a photoelectric measuring sensor (25) receives measuring light reflected by the test copy. As a function of an existing density difference between the test copy and a reference copy, corrections of the exposure values are determined in such a way that a copy exposed under the new exposure conditions has the density values of the reference copy.

Abstract: In an illuminating system for color enlargement or copying, three color filters of maximum density and a shutter may be introduced into the light beam in a continuous motion. The direction of travel of the filters is normal to the direction of travel of the shutter. To avoid a change in the color composition of the copying light when only the shutters are adjusted, the effective shape of the shutter introduced into the light beam is varied dependent upon the depth of insertion of the shutter into the light beam. For this purpose, the shutter may comprise two parts: a shutter strip and auxiliary shutter strip, the position of which relative to the corresponding shutter strip is different depending on the depth of insertion.

Abstract: An illuminating device for a color printing apparatus having color filters insertable at varying amounts into the printing light beam has a light-conducting shaft and a variable aperture diaphragm both of which have substantially rectangular cross sections whereby the color content of the printing light beam is maintained substantially uniform. The light-conducting shaft has the form of a frustum of a square pyramid and the variable aperture of the diaphragm has a rectangular form. The light source has an ellipsoidal reflector, and the light beam emerging from the illuminating device is channeled through a light mixer.

Abstract: A light mixing compartment for a projector, such as incorporated in a photographic copier or enlarger, has four convexly curved side panels disposed between the entrance and exit, which are covered by light diffusing plates. The cross sections of the compartment parallel to its diffusing plates are cylindrical or rectangular with the sides having different angles of inclination adjacent the entrance from those at the exit. The ultimate slope of the sides adjacent the exit preferably is a right angle, and the overall shape of the convexly curved sides is adjusted to control the marginal brightness of the light format emitted from the compartment. The four convexly curved sides are held together by appropriately shaped bands riveted to the sides for securing them together.

Abstract: An illumating device for a photograph enlarging or copying apparatus has a pair of lighting compartments having different characteristics movably connected to each other and mounted to slide back and forth across the optical axis. The light compartment better adapted to the particular format to be copied is positioned in line with the optical axis. A diffusing lens is insertable in the light emergence side of the lighting compartment being utilized, and the diffusing lens may be movably mounted so as to position different areas in the path of light emerging from the compartment.

Abstract: The color mixing compartment of illuminating equipment for a photographic enlarger includes two parts. The part adjacent the light-admitting surface is a truncated pyramid. The part adjacent the light-emerging surface is substantially a parallelepiped having side faces disposed substantially perpendicularly to the light-emerging surface. A diffusing plate having a substantially uniform thickness is arranged at the light-admitting and light-emerging surfaces of the mixing compartment.
