The invention relates to a device for registering several at certain intervals successively arranged printing forme cylinders of a multicolor rotary printing press.

In the case of multicolor rotary printing, the printing forme cylinders arranged one after the other in the direction of flow of goods must be inserted into the machine with their complementary printing forme design, so that each following printing forme cylinder always works exactly into the pattern printed by the preceding printing forme cylinder. If the distance between the printing lines of the printing form cylinder in the Maschin = equal to the circumference of the printing form cylinder is _r is this alignment

of the individual printing forme cylinders relative to one another simple. It just has to be on each of the printing form cylinders mark a control point which has a certain position in relation to the design, and make sure that at all of the printing forme cylinders inserted in the machine have the same control point in relation to the printing area is aligned. However, it becomes difficult if the distance between the printing lines of the printing forme cylinders is nio'rvc equal to their scope.

This is where the invention provides a remedy, namely by means of it. that on each printing forme cylinder one for the common design of the printing forme of all printing forme cylinders a certain constant position having control point is formed that further on each printing forme cylinder in certain constant position to the control point one arranged in a circular arc concentric to the axis of the printing forme cylinder Scale is applied, the division of which is transposed to the diameter of the printing forme cylinder equal to the difference in the circumference of the printing forme cylinder "and of the distance between the print lines, and that on the machine frame in the area of each Printing forme cylinder a reference plane is marked, the position of the reference plane relative to the associated Printing forme cylinder and its printing line for all printing forme cylinders is the same.

The individual printing forme cylinders that belong together with regard to a specific design to be printed are now inserted into the machine in such a way that the first printing forme cylinder with the one to be printed Material comes into contact first when passing through the machine, with the first graduation mark on the scale

*, the reference plane is brought into congruence. With everyone The respective further division of the scale with the reference plane becomes the further printing forme cylinder brought into cover * The printing forme cylinders inserted in this way work - synchronous rotation all printing forme cylinders required - exactly true to the pattern with each other »in such a way that the design parts of each following printing forme cylinder correspond exactly to those of cover the same design parts printed on the previous printing forme cylinder or those already printed Design sections complement each other exactly with regard to the overall design to be produced, although the print line spacing the individual printing forme cylinders differ from the circumference of the printing forme cylinders.

If the printing line spacing of the printing forme cylinder is smaller than the circumference of the printing forme cylinder, then the scale is in the opposite direction to the direction of rotation of the The printing forme cylinder is numbered in ascending order and is the printing line spacing however larger than the circumference of the printing cylinder »then the increasing numbering takes place the scale in the direction of rotation of the printing forme cylinder.

Different types of printing forme cylinders, in particular Ruiid stencils for screen printing machines are equipped with end pieces on the face. In this case it is useful if the scale on one of the front end pieces of the printing fornate cylinder attached is.

The invention is explained in more detail with reference to the drawings by means of an exemplary embodiment, without it to be limited.
