SU7475A1 - Glass Cylinder - Google Patents

Description

The proposed machine for printing from a glass cylinder is intended to mechanically reproduce glassy originals of originals. The machine is equipped with a glass rotating cylinder or segment.

In the schematic drawing of FIG. 1 is a side view of the machine; FIG. 2 and 3 are partial longitudinal sections thereof and FIG. 4-part. ,

FIG. Figure 1 shows a glass cylinder 21 which is associated with a paint roller 22 of a chain or gear-wheel transmission. Above the paint roller 22 is another roller 23, to rub paint when it is fed to roller 22. A smaller pressure roller 24 is located below the cylinder 21 with a rim of some elastic material, for example rubber, to press down the sheet to be printed paper, which, in doing so, is placed on the table 25.

Since before the process of printing is not glassy, the cylinder has to be subjected to various manipulations usually adopted in glasslography, in order to be able to carry them out, the paint rollers are arranged with precious stones.

or, as shown in the drawing, the entire glass cylinder is discharged to the side, where it is made above, it is all necessary. To this end, the glass cylinder 21 is resting in a double bearing 26, whereby during printing its axis is held in the right half, being closed at the side by the locking plate 27 (Fig. 1), which, in case of removing or installing the axis backwards Turns around the bottom of the bolt drawing. To prepare for printing, the cylinder 21 rolls along the double bearing 26 to the left ' at its end, where the axis of the roller closes with a locking plate 28 arranged as rotary around its bolt as the locking plate 27. From above and to the left of the bearing 26 there is a process 29 frame 30, which serves to hold the brush holders 31 with brushes 32 inserted into them. The latter serve to rub the surface of the cylinder 21 with the necessary compositions.

The system for moving the brushes 32 along the generatrix of the cylinder 21 is shown in two variants in the drawing, in FIG. 2 and

.3, in which the first version refers to the gradual movement of the brushes using a screw rod with two different cutting directions from the edges of the drum to its middle and back, while the second option allows the brushes to make frequent movements back and forth by using rotating cams . FIG. 2, the number 33 is indicated by a screw rod cut into one half of the right, half the length of the left thread, wherein the rotation of the gear gear 34 from the chain 35 and the gear 36 using the handle 37 mounted on the axis of the drum 21 makes it possible to move the brush holders 31 from the edges of the roller 21 to its middle or in the opposite direction, depending on the direction of rotation of the handle 37. FIG. 3, the brush holders 31 are mounted on a smooth roller 38 and set in motion from the roller 39, at the end of which a gear gear 34 is mounted, set in rotation, as indicated above. At the same time, the cams 40, which are tightly mounted on the roller 39, are provided with cuts of proper closed curvature, so that when these heads 41, attached to the brush holders 31, are directed in these cuts, the latter are also moved forward for a short distance.

One of the methods commonly used in glass-making is an imprint of a given original (font or image) on a glass surface, with the aim of subsequently fixing on this surface a given imprint in the form of a cliche, from which it is then printed. Such an imprint of the original takes place in the proposed rotary apparatus by overlaying on the surface of the cylinder 21 an original, which is indicated in PA. 4 figures 42. In order to uniformly press this original onto the cylindrical surface 21, there is a clamping

adaptability that. It consists of a flexible shell 43 and a ring 44, provided with curved processes, which are fastened with a bolt 45. In this case, the shell 43 can be, for example, of wooden plywood, upholstered inside with felt, and the ring 44 is made of flat steel. If the width of the original along the generator cylinder 21 is too large to be evenly pressed by the ring 44, then two or more such rings can be taken, and tightening the nuts to the bolts 45 in the rings can be done for everyone at the same time, using any longitudinal tool.

The subject of the patent.

1. A machine for printing from a glass cylinder, characterized by the use of a rotating glass segment or cylinder 21 (Fig. 1-3) with colorful rollers 22, 23 and a roller 31 with brushes 32 located above it, and under it a pressure elastic roller 24 Which segment or cylinder is mounted with its axles in a double bearing 26 with two locking plates 27 and 28, in order to move it to the brushes 32 to clean its surface before transferring the pattern onto it.

2. In the machine indicated in item 1, a device for moving the brushes 32, consisting either (fig. 2) of a rotating screw rod 33 with opposite threads, or (fig. 3) of a smooth roller 39, provided with cams 40 with a slit for the head 41 of the brush holder 31.

3. When using the machine indicated in item 1, use the device for pressing the translated original onto the surface of a segment or cylinder 21, which consists (Fig. 4) of a flexible shell 43 and a ring 44 with curved processes for a tightening bolt 45.
