Description

In contrast to the well-known copy machines, on which printing of nano-LED on one side of photosensitive paper, the proposed apparatus is intended for two-sided printing using special double-sided photosensitive paper, as well as for printing and on ordinary single-sided paper.

FIG. 1 shows an obdiy device; in fig. 2-partial cross-section through spherical glass (on an enlarged scale); in fig. 3 and 4-part coupling of the driver with the chain; in fig. 5 shows a top view of the leash; in fig. 6-sec e to .4 / 1 in FIG. five.

The lead / and, with two traces in it, with a sheet of two-sided photosensitive paper 2 between them, carried along by chains, slides along the convex surface of cylindrical glass 3, the passage iodine by glass rods 4. The path of the lead is shown in FIG. I arrows B, V., and 2.

When passing under the roller 5, the leash with behind / rolled drawings in it and the photosensitive paper 2 is taken out of the engagement with the chains and enters the receiver 6. The articulated leash articulated chains 7 are put on the sprockets 8 and slide with their rollers .9 along the guide 10, rollers 11 are observed to prevent chains from jumping off the guides. Sprockets 8 are seated on rollers 5 and 12. One of the rollers is set in rotation by an electric motor or clock mechanism (not shown). With one-sided m printing on the upper frame (Fig. 1), the tracing paper and photosensitive paper consumed from the roll 13 are pressed against the glass 14 by an endless web U5 and, having passed the path shown by arrows .4 and.4, go to the receiver 16. With one-sided printing on The bottom frame (with glass, 3) is charged using a driver /, as with double-sided printing, but paper is fed from roll 17. Glass rods 4. Pressing paper and drawings to glass 3, pin 62470-2 -

live in the grooves of the guide collars 18, rising when passing under the leash. The illumination for printing is carried out by a brush with lamps 19, and with one-sided printing the three lamps located under glass 3 turn off. The flap 20 serves to harden the charging area (table 21, the flaps 22, 23 and 24 reflect the light of the lamps inside the apparatus.

The driver / has four flaps 25 hinged for clamping four formatted boxes with dimensions of 203 x 288 mm (a large drawing is clamped with several covers). The drawings are pressed against rubber bands 26 and 27 attached to the sole and cover of the driver. The covers are provided with two latches 28 each. At both ends of the driver are hinged levers 29 with flat springs 30. The levers 29 with cutouts in them are coupled to the studs 31 of the chain 7, with the springs 30 pressing the levers and the chains. At the approach of the chain driven lead to the wedge 32 located under the roller 5, the latter depresses the lever, overcoming the resistance of the spring, and the lead coming out of engagement with the chain falls into the receiver 6. The drive unit and electrical equipment are mounted at the bottom of the apparatus on the base frame 33.

Subject invention

Claims (3)

1. A device / for copying blue tiles, using a frame with cylindrical glass and an endless cloth, characterized in that, to copy the blue, on both sides above the cylindrical glass, a clip for glass rods is installed, which presses cripples with blue against the glass during copying. 2. In the apparatus of claim 1, use additional cylindrical glass and an endless web located above the glass in order to simultaneously copy and on one side of the blue. 3. In the apparatus of clause I, use of a device for clamping cripples with blue consisting of a leash with tendrils on levers for putting on pins, moreover, wedges are installed under the roller to move the levers from the shafts. cs: n
