A device 10 for cutting flat material or tissue has a table 12, which as Carrier for a support 14 of a variety of

The invention relates to a device for automatically cutting flat material, e.g. B. serves. A tool slide 16, which is located on a tissue, with a surface carrying the material, the table 12 transversely spanning the main slide with a in a coordinate direction (^ -coordi- 21, is mounted movably over the surface of the table 12 nate) relative to the support surface feasible in two coordinate main slides indicated by the arrows X and Y and with one of the main slide 40 in data directions. On the tool blade carried, with this in the first coordinate 16, a cutting device 36 is movable with a cutting direction (^ coordinate) and this tool is arranged in the form of a blade 18. The opposite in a second coordinate direction cutting device 36 is on the tool slide 16 so (v-coordinate) movable, attached to a tool that there is a slide with respect to the table surface cutting head, which can be moved up and 45 to any specific point carries movable cutting tool and with a can, depending on setting signals, located near the cutting tool pressure plate. the device via the cable 19 from a.

Press the cutting tool together in order to be fed. The tool slide prevents it from moving during the cutting process. Ability to move the blade 18 in the cutting position or abutment, which would lead to an imprecise cut, and to move the tissue support 14 along any line on the cutting tool during the upward stroke of the cutting tool, which line may be straight or curved.

The object of the invention is to further eliminate this disadvantage in the direction indicated by the arrow θ. The aim is to reduce the friction between the pressure applied as a function of signals from the input plate and the surface of the flat material on a device that can be rotated about its own axis, without any risk. During at least part of its stroke to run so that a change in position of the flat material penetrates the blade 18, the upper support surface 28 occurs, and it should be ensured that also with the table 12.
