Description

Rotary printer with a rotating support device for a Flexible printing form attached to its periphery The invention relates to a rotary printer with a rotating support for a flexible one attached to its periphery Printing form with lines running parallel to the axis of rotation and one rotating with it cooperating line-wide device for pressing and conveying a to be printed Arch, in which the beginning and the duration of the rotating interaction of the printing form support device with the pressing device for printing non-contiguous text parts of the printing form can be changed to form a coherent text on the sheet.

So it is essentially a matter of two or more spaced apart Texts or text parts of the same or different printing forms on the one hand each other to be approached so that they come closer together to the imprint on the sheet to be printed and on the other hand, the size of the printing form or text parts to be printed can be variably determined.

The rotary printer is primarily used for machine purposes Work preparation in industrial companies. Here is one for a larger number Text that remains the same from printing processes (header text, e.g. number of items, order number, Designation, delivery date, type of material, etc.) with one for each or after only a few Printing processes changing text (operation text) on the limited area, e.g. B. a piece of paper (usually DIN A6 format), together in one Operation closed or brought closer to each other for printing. The description of the The operation is usually of different lengths, so that in many cases a one-line text is sufficient, while in other cases two or three and more lines are necessary for a job description.

On the other hand, it is sometimes necessary to have several in the printing form Work step texts lying separately from each other on a print sheet one after the other to be printed. In particular, this is used to create one or more work plans z. B. to pull out only turning, milling or punching, etc.

With the work preparation, however, the possibility of using the Subject of the invention is by no means exhausted, but it can be applied to all Use eligible areas. This is particularly true for procurement in factories or trading establishments too. Here are for the incoming orders Mirrored originals are written, of which both the order confirmations, Invoices, delivery notes, receipts as well as all of the organizational Completion of the order required slip for the own company printed will. Since the orders, especially in trading companies, are often a series of different goods, each having different departments of the Concern, it is expedient if from the order the one common Department-related goods or items separately on an order slip can be printed out for this department. The individual Positions of different sizes.

The device can also be used for accounting purposes possible.

The aforementioned requirements of modern machine work preparation, of procurement, etc. is shown and described by the example Device taken into account that according to the invention either with a continuously rotating drum that carries the printing forme and is inevitably driven Pressure device or the continuously rotating and when it runs up on a Pressure roller this temporarily one or more times during the printing of a sheet driving printing forme carriers made up of several on the shaft of the pressure device or of the printing form carrier partly rotatable and lockable and partly rotatable as well radially in or out of the area of their interaction with the printing drum or pressure roller there is optionally adjustable and definable pressure segments.

It is completely irrelevant what types of printing processes are used or use of printing forms. It can e.g. B. printable mirror writing originals or from the outside or from the inside colored printing forms, such as metal grid foils, plastic high-pressure forms, wax matrices, yes, even type printing sets are used. However, printable ones are best suited Mirror writing originals.

The rotary printer designed according to the invention has means an interrupted contact pressure during an operation of the printing device effect and both in terms of the duration of their ineffectiveness between the partial printing processes as well as with regard to the duration of action during or several partial printing processes can be set.

The drawing shows an embodiment of the subject matter of the invention shown and illustrates a longitudinal section of an embodiment with multiple adjustable pressure elements.

The printing drum i is with the carrying device seated on the shaft 53 i a z. B. inevitably connected by spur gears.

On the printing drum i is a printing forme 2, which is of a known clamping device 2a is held. With the printing drum i inevitably Circumferentially connected are arranged on the shaft 53 pressure segments 54, 55, 56, 57, 58. The group 55, 56, 57, 58 of the pressure segments can be compared to the pressure segment 54 adjust relative in the circumferential direction. Fixed or detachable with the pressure segment 55 connected are the pressure segments 56, 57, 58. These have elongated holes 59 and can consequently selectively in and out of the area of cooperation with the printing drum or pressure roller are brought. The pressure segments can be in their position by known Facilities, screws or the like., Are secured.

The selection of the changing printing forme part is made by Setting the group of pressure segments 55, 56, 57, 58. Determining the size of the section is carried out by switching on the additional pressure segments accordingly 56, 57 or 58.

The sheet to be printed 5o is placed on the feed table 45 and first transported through the machine by the pressure segment 54. Here is he is moistened in a breath-like manner by the pivotably mounted moistening device 39.

After the consistent text has been printed, the sheet remains 5o while the printing drum continues to move with the printing form until the Print segments 55 and optionally 56, 57, 58 reach the print line and the Imprint of in its distance from the unchanging text and in its size changing text.

Of course, the device can also be designed vice versa be that instead of the printing drum, the mentioned group of printing segments 54, 55, 56, 57, 58 is used, the printing form being on the latter. In this In the case, the pressure segments temporarily work together with a pressure roller.
