MOUNTING TABLE

Abstract: Mounting table which has a work surface for mounting printed originals on a carrier (1). The carrier is used as a mount for photographic reproduction in offset printing. According to the invention, the work surface is designed as a mounting panel (2) which is insertible in guide grooves (3) in frames (4, 5, 6, 7) which surround the work surface of the mounting table, and this mounting panel (2) is transparent and has visible, suitably etched lines (8) which mark determined formats, for example, A3-A8 format on the carrier (1). The mounting table is further designed to be used for a carrier (1) in the form of a translucent paper sheet with no pre-printing. The mounting of printed originals may thereby be simplified, cheapened, made quicker and less tiring.

Description: .PUNTING TABLE The present invention relates to a mounting table, with a work surface for mounting of printed originals on a carrier. This carrier is used as a mount for photographic reproduction in offset printing. The pre-printed mounts hitherto used in this Art cost prin¬ ters a considerable amount of money in preparation, and printers must always have a generous stock of such mounts. The mounts must be stored at roαn temperature and at a predete__mindes level of humidity in the storage roctn. If these requirements are not met, errors will easily occur in the printing run operation, in parti¬ cular in multicolour printing. Prior Art mounts for mounting printed originals are fixed to a translucent panel on a light table. The entire panel of these light tables is powerfully illuminated in work on the light table, even if the printed original is only to be set in a portion of the mount. This powerful illumination light is extremely tiring for the printing staff who often spend an entire day working at the mounting table. . The object of the present invention is to obviate these and other drawbacks inherent in mounting tables, this object being attained in that the present invention is given one or more of the characteristic features as disclosed in the appended Claims. One ___±)odiment of a mounting table in accordance with the invention is shown on the accompanying Drawings. In the accompanying Drawings: Fig. 1 is a front elevation of the mounting table? Fig. 2 is a side elevation of the mounting table, partly in section taken along the line II-II in Fig. 1; Fig. 3 is a front elevation of the rrounting panel for the mounting table according to the present invention; Fig. 4 is a section through the mounting panel taken along the line IV-IV in Fig. 3; Fig. 5 is a rear elevation of the mounting panel; Fig. 6 is a magnified cross-section of the mounting panel with a carrier for printed orginals on its work surface, and Fig. 7 shows the light box of the mounting table, seen fron the front. The mounting table according to the present invention is provided with a work surface for mounting printed originals on a carrier 1, which consists of a translucent paper sheet with no pre-printing. The printed original, which, for example, may consist of a printed text in newspaper articles, column paste-up for a page of a newspaper, photographs, advertisements, the text of a book page, etc. , is fixed to the carrier 1 for example using tape, in exact positions. The work surface of the mounting table is designed as a mounting panel 2. This may be inserted in guide grooves 3 in a table frame 4, 5, 6, 7 of the mounting table. The grooves 3 are of a configuration which has been adapted to the cross-section of the mounting panel. The table frame, which surrounds the work surface, consists of the top frame 4, a first side frame 5, a bottom frame 6 and a second side frame 7. The table frame 4, 5, 6, 7 is dis¬ posed to be adjustable at angles between a horizontal and a vertical plane on the mounting table. Apparatuses for the.angular adjustment of the table frame 4, 5, 6 and 7 are not shown on the Drawings, since these may be designed in many different manners. The motmting panel 2 which constitutes the work surface of the mounting table is transparent, suitably of Plexiglass. It is provided with visible, etched lines 8 which mark determined formats, for example A3-A8 format on the carrier 1. The mounting panel 2 is insertible frαα the side into the guide grooves 3 in the table frame 4, 5, 6 and 7 of the mounting table. The edges of the mounting panel 2 may suitably be provided with a thin, robust steel frame. The mounting panel 2 may be made for different types of mounting work, for example for format A0 to A4, for newspaper pages, for book pages and for advertisments. For each such type of mounting work, a mounting panel 2 may be in¬ serted on a lower shelf plane 9 of the mounting table. A light box 10 is disposed as the rear piece of the table frame 4, 5, 6 and 7. The light box 10 is divided into sections A, B, C, D, E, F, G, H with a determined format, suitably A-format, which corresponds to the etched lines 8 of the mounting panel 2. The sections A-H are separated and discrete from one another by means of wholly opaque partitions 11. Each section A-H in the light box 10 has at least one light source, suitably in the form of two fluorescent tubes 12. The source is connected to the mains by the intermediary of a switch (not shown) which is operated by a key 13 on the front face of the bottom frame 6. The light intensity is adjustable by means of a knob 14. The front face of the light box 10 is covered with a frosted glass pane 15 which is inserted in the table frame 4, 5, 6 and 7. In order to provide good illumination of the etched lines 8 on the mounting panel 2, the upper face of the frosted glass pane 15 is covered with a clear glass pane 16. The underface of the frosted glass pane 15 is also covered with a clear glass pane 16. The frosted glass pane 15 with its clear glass panes 16 is insertible in slide grooves 17 in the table frame 4, 5, 6 and 7. The slide grooves 17 are of a configuration which corresponds to the cross- section of the panes. The table frame 4, 5, 6 and 7 is supported by a horizontal top section 18 and two support leg pairs 19 on the mounting table. The support leg pairs 19 are interconnected with one another by means of an upper shelf plane 20 for mounts and the lower shelf plane 9. The shelf planes 20 and 9 have mutually registering grooves for mounting panels 2 which are inserted in a vertical position. The mounting panel 2 is provided with a horizontal rule 21 on its upper face and with a vertical rule 22 on its underface. Both of the rules are calibrated in a millimetre scale which begins at both ends of each of the rules. The rules also have dimensional markings for the graphic dimensions according to the Cicero System. Moreover, the rules are provided with the dimensions of the different sheet formats which are shown on the Drawings with the formats A3-A8 shown in upright, standing format. The ends of the horizontal rule 21 are guided in vertical grooves 23 in the mounting panel 2. The grooves 23 run along the vertical edges of the mounting panel 2. The ends of the vertical rule 22 are, in a corresponding manner, guided in horizontal grooves 24 in the .counting panel 2 running along its horizontal edges. Handles 25 for moving each respective rule 21 and " 22 are disposed in the ends of the rules and are provided with a base portion which is shiftably guided in the grooves 23 and 24, respectively. The horizontal rule 21 passes with a play of 2 millimetres above the translucent paper sheet which is used as a carrier 1 in the same manner as a mount. In order to pass easily across the printed matter which is mounted on the paper sheet, the edges of the rule 21 are bevelled. In order that the vertical rule 22 be easily movable on the underface of the mounting panel 2, it has been provided with an edge strip 26 which runs about the entire edge of the underface of the mounting panel 2. This edge strip 26 is designed with slightly greater thickness than the vertical rule 22. To make the carrier 1, in the form of a translucent paper sheet, readily detacheable in its fixation to the mounting panel 2 so that the etched lines 8 are easily visible, each half field of the uppper face of the mounting panel 2 is provided with a grid- work of ditchlike grooves 27. These are mutually interconnected and are connected to a passage 28 in the mounting panel 2. The passage 28 extends out to one edge of the mounting panel where a connection member 29 for a vacuum hose may be coupled. The points of intersection of the grooves are made in the form of round recesses 30 in order to provide better adhesive suction of the translucent paper sheet for the rrounting. The mounting table is also provided with a shelf 31 for mounting work materials such as tape, knives and the like. This shelf 31 is supported by the two support leg pairs 19. It is nonrotatably fixed to the support leg pairs 19 and is disposed adjacent the second side frame 7 of the mounting table. In order to facilitate work at the mounting table, its bottcm frame 6 is provided, on its front side, with a tool shelf 32 and the shelf 20 for the translucent paper sheets which are used as carriers 1. The mounting table according to the present invention en¬ sures, as compared with prior Art mounting tables, a higher degree of accuracy and a shorter time input requirement. This makes for enormous savings in reduced work time and a reduction in waste paper in newspaper printing, apart fron the above indicated savings which are made since no pre-printed mounts are necessary.
