Printing unit on rotary presses for printing a security signature on notes of value with a detachable coupon.

The invention relates to a printing unit on rotary machines with at least one cylindrical cliché for printing a Security signature on notes of value with a detachable coupon, with the security signature running in the direction of the dividing line and this overlaps.

Such security signatures provided with detachable coupons Bills of value, in particular lottery 3 marriage, are known and allow when redeeming the voucher, togetherness in a simple and secure way a presented coupon with the relevant tribes before in ascertain, since when the two parts are put together must correctly add the sections of the security signature present on the coupon and on the master certificate.

In order to have different security signatures from ticket to ticket to obtain, it is already known that instead of a single dividing line between the master certificate and the coupon, numerous parallel and closely zigzag rows of perforations or preformed tear lines to be provided, the entire area being printed with a signature. In this way, when it is torn off, its coupons are created from the master scheme a completely arbitrarily jagged edge that randomly divides the signature print »This well-known measure to achieve a from Schein zu Coupons which can be detached in different ways, however, have the disadvantage that when a coupon is torn off along a random zigzag line there is a risk that the separating edge on the master note or on the coupon may be accidentally detached if handled carelessly is changed by further paper strips along other preformed dividing lines, which later becomes a mismatch when the note is redeemed can fake coupons and certificates.

Furthermore, notes of value are known, which are the dividing line between Coupon and master certificate intersecting, have different imprint in the form of a different password from one note to the next. When producing these notes, the printing plates for the Passwords are changed according to the number of differently selected passwords, which is uneconomical.

Furthermore, notes of value with detachable coupons are known in which a note represents the section of a printing sheet provided with diagonal stripes or patterns, which has the multiple width of the individual section, the length of the individual sections being chosen so that they do not coincide with the Compensate for the length of the print roller. This avoids repeating the same pattern in different sections. The disadvantage here is that the pattern running diagonally across an entire sheet including a large number of bills cannot be printed in one operation with the numbers of the bills, since this pattern also covers the numbers, and that a large number of different stripe patterns on a corresponding multi-part cliché carrier must be provided. The number of strips overlapping a dividing line is also limited.

The invention is based on the object of creating a printing unit of the type described above, with which notes of value which only need to have a single straight perforation or preformed dividing line, preferably in one operation with the number imprint using only one cliché, are simple and economical can be printed with a security signature, which varies from note to note.

To solve this problem, the invention is characterized in that that the plate carrier rotates on the rotatable shaft of the printing unit arranged and by means of a stepping mechanism to generate a security signature shifted from note to note after each Shaft revolution can be switched one step further.

Further features of the invention emerge from the subclaims.

The invention is based on the drawings of an exemplary embodiment explained in more detail. Show it;

According to FIG. 1, the security signatures printed with a printing unit according to the invention consist of wavy lines 18 and 19 which overlap the perforation line 7 between the master note 2 and the coupon of a bank note numbered 4-6 in different places. The image printing of the notes of value, which are still connected in the form of a larger sheet 1, is not shown. The perforation 7 can be produced in one operation with the numbering or else before or after. The security signature can consist of aperiodic wavy lines, zigzag lines or the like instead of periodic ones. In the example under consideration, the mutually offset wavy lines 18 and 19 have a different color and at least one of the lines 18 and 19 is offset from note to note by a certain amount in the direction of the perforation line.

FIG. 2 shows a master certificate 2 with an associated coupon 3, while in FIG. 3 the master certificate and coupon do not belong together, which can be seen immediately from the non-complementary see signature .

The signature printing unit is advantageously combined with the numbering printing unit. In the example according to Figures 4, 5 and 6, for two-color printing of the numbers and the see rheits signature, two with a common

seed printing cylinder 10 cooperating numbering cylinder 8 and 9 provided, on the shafts 11 and 12 the required number of numbering machines 13 and 14 (FIGS. 5 and 6) that print partly horizontally and partly vertically, as well as the required signature clichés 20 and 23 are arranged. The cylinders 10, 11 and 12 rotate in the direction of the arrows according to FIG. 4, and the sheets 1 to be printed are in the direction of of the arrow passed between the printing cylinder 10 and the numbering cylinder. Known control cams 15 and 16 with the indexing levers of the numbering machines work together, serve for the step-by-step advancement of the numbering machines with each revolution.

In the example under consideration, the cliché carriers 21 sit for the signature clichés 20 rotatably on the printer shaft 11 (Figure 5), while the plate carrier 24 for the signature plate 23 rotatable on a means the support hub 26 is mounted in a rotationally fixed manner with the disk 25 connected to the printing unit shaft 12 (FIG. 6). The ring-shaped plate carrier 24 has an internal toothing 27 (Figure 7) into which the pawl 28 of a ratchet mechanism engages. Sine control role 30 of this rear derailleur works with a fixed cam 31 together. ,, through which, similar to the step-by-step forwarding of the Numbering works, with each revolution of the printing unit shaft 12, the pawl 28 is actuated and thereby the plate carrier 24 relative to the shaft 12

is rotated further by a small angle. One bouncy in the Counter-pawl 32 engaging inside toothing 27 prevents the cliché carrier 24 from rotating back after each advance. According to FIG a previously recognized image misprint on the sheet, a further indexing of the plate carrier 24 is avoided by the control line 31 is moved out of the orbit of the control shaft 30.

With the printing unit described, the same, unshifted signature lines are thus created in one by means of the clichés 20 from bill to bill Color and with the cliché 23 from note to note slightly offset signature lines are printed in a different color, advantageously both signature patterns, as shown in Figures 1-3, overlap.

The position of the cliché carrier 21 and the disk 25 can be adapted to different paper and note widths by axially displacing them on the shafts 11 and 12, respectively.
