DE2065865A1 - DEVICE FOR THE PRODUCTION OF LIKE FLAT CARRIER - Google Patents

Description

The present invention relates to an apparatus for manufacturing similar flat carrier with similar representation, e.g. signs, printed circuits or the like, whereby Flat material is provided with a plurality of representations in a reproduction device. The representations are then, if necessary after graphic transfer of the representations onto another sheet material, e.g. from a photographic film onto a sheet metal, individually for the production of individual ones Carrier cut out.

The invention is based on the object of a simple device to specify the exact reproduction of representations. The device according to the invention is characterized in that that the reproduction device has a fluoroscopic bell that can be placed against the flat material and by the same is removable and attached to the side facing the flat material an original or slide of a representation can be, wherein the fluoroscopic bell is attached to a movable suspension, which a flat, play-free concern allows the fluoroscopic bell in a precise position on the flat material. The fluoroscopic bell can preferably be at least approximately parallel by means of one or more be connected to the flat material lying leaf springs with a holder.

The invention will now be explained in more detail with reference to the drawing, which shows an exemplary embodiment of a device according to the invention shows.

FIG. 1 shows the device for reproducing representations in side view, partly cut and

Figure 2 shows a plan view of the device.

For the production of signs that have a representation in the form of writing, field division, frame and the like, is usually a photographic and photochemical way first produced a cliche, which in certain mutual relation

Order has a large number of individual representations. For this purpose, a film is first made using an original drawing or a reduced slides of the same created, which film then directly to the production of the ClichS on photochemical Ways serves.

The device shown is used to produce the film. It has a fluoroscopic bell 1 that is closed at the top is and a light source 2 carries. The lower, rectangular opening of the bell 1 is held in a frame 5 with a Covered glass plate 3, attached to the underside of an original drawing or a slide 4 in a certain position and the Plate 3 is completely covered in the rest. The frame 5 is connected to a carrier 7 by means of two leaf springs 6 and thus held vertically movable with respect to this carrier 7 in a certain horizontal position. On one with the carrier 7 connected sleeve 8 is a sleeve 9 with a U-shaped lifting fork 10 is guided vertically. The arms of the fork 10 grip under pin 11 of the frame 5 and are used to temporarily lift this frame and the fluoroscopic bell 1. A compression spring 12 holds the sleeve 9 and the lifting fork 10 normally in an upper end position in which the frame 5 or the glass plate 3 is lifted from a vacuum clamping table 13 or a stretched film 14. A push magnet 15 is used for lowering of parts 9, 10 and 1-5 in the position shown, in which the picture or slide 4 rests on the film 14. On the frame 5 a crosshair illumination 23 is attached, which allows a reference cross to be exposed on the film.

Either the carrier 7 or the clamping table 13 is on one which is adjustable according to right-angled coordinates, not shown Cross slide attached while the other of these parts is fixedly mounted. This clamping table can be adjusted in the X-direction and Y-direction by means of stepping motors and spindles will. With such an adjustable compound slide, either the clamping table 13 or the carrier 7 is connected. It it is thus possible, through appropriate position control, to determine the relative position of the frame 5 or of the picture or slide with respect to the clamping table 13 or film 14 can be adjusted step by step as desired, the achievable precision of the adjustment only on the size of the unitary step and the accuracy depends on the mechanism.

By means of an automatic position control, line-by-line individual representations can now be displayed on the film 14, by gradually shifting the raised fluoroscopic bell, then lowered it and, with the bell lowered, the lighting 2 is switched on. The leaf springs 6 result in a vertically easily movable, horizontally, parallel to the film on the other hand quasi rigid, simple and cheap connection of the bell with the carrier 7. The original or slide can therefore always are placed against the film 14 parallel and free of play and in a precise position with respect to the carrier 7. This can take turns one line from left to right e.g. in X-direction, then after appropriate adjustment in Y-direction a second line can be exposed in the X direction from right to left and so on. In two specific positions it is presented

or the crosshair illumination after the individual images have been recorded 23 is switched on and exposes a crosshair on the film at two locations outside the representations.

The film is now developed and then a corresponding cliche is produced photochemically. With this cliche plates, e.g. metal plates, are then printed, whereby apart from the individual representations the two crosshairs are reproduced will. This means that the panels are ready to cut out individual signs, each with a representation of the purpose each plate is precisely positioned using the two crosshairs.
