Abstract
A method for correcting an alignment of a cutting layer made up of stacked, sheet-format product in the form of sheets in relation to a cutting plane of a cutting blade of a cutting machine, and a cutting machine. The cutting machine has a feed saddle for displacing the cutting layer in the direction of the cutting plane of the cutting blade, wherein the feed saddle is adjustable in its alignment in relation to the cutting plane to change the alignment of the cutting layer pressing against the feed saddle in relation to the cutting plane. The respective sheet is provided with at least one cutting test mark, wherein the respective cutting test mark has a coloration changing in the feed direction of the feed saddle.

A method for correcting an alignment of a cutting layer made up of stacked, sheet-format product in the form of sheets in relation to a cutting plane of a cutting blade of a cutting machine, wherein the cutting machine has a table for receiving the cutting layer and a feed saddle for displacing the cutting layer in the direction of the cutting plane of the cutting blade of the cutting machine, wherein the feed saddle is adjustable in its alignment in relation to the cutting plane to change the alignment of the cutting layer pressing against the feed saddle in relation to the cutting plane, wherein a respective sheet is provided with at least one cutting test mark, wherein the respective cutting test mark has a coloration changing in a feed direction of the feed saddle, wherein the method comprises:
- a) displacing the cutting layer by means of the feed saddle in the direction of the cutting plane of the cutting blade such that the cutting plane intersects the cutting test marks;
- b) cutting the cutting layer using the cutting blade to form a cut front side having a frontally visible colored pattern formed by the cut-through cutting test marks;
- c) determining a coloration of the frontally visible pattern;
- and
- d) determining whether deviations of the alignment of the cutting layer from an intended alignment are present, wherein the determination is carried out on the basis of the coloration of the frontally visible pattern, wherein upon the presence of deviations, the alignment of the feed saddle in relation to the cutting plane is changed to correct the alignment of the cutting layer.
A cutting machine for cutting a cutting layer made up of stacked, sheet-format product in the form of sheets, wherein a respective sheet is provided with at least one cutting test mark, wherein the cutting machine has a table for receiving the cutting layer, a cutting blade, and a feed saddle for displacing the cutting layer in the direction of a cutting plane of the cutting blade of the cutting machine, wherein a respective cutting test mark has a coloration changing in the feed direction of the feed saddle, wherein the cutting machine has an adjustment device for adjusting an alignment of the feed saddle in relation to the cutting plane, for changing an alignment of the cutting layer pressing against the feed saddle in relation to the cutting plane, wherein the cutting machine has a system for determining and correcting any deviations of the alignment of the cutting layer from an intended alignment of the cutting layer, wherein the system has at least one image sensor, wherein the image sensor is configured, after a cut-through the cutting test marks, to acquire a frontally visible colored pattern formed by the cut cutting test marks, wherein the system has an evaluation device, wherein the evaluation device is configured to determine on the basis of a coloration of the frontally visible colored pattern whether deviations of the alignment of the cutting layer from the intended alignment are present, and wherein the system is configured, upon the presence of deviations, to adjust the feed saddle in its alignment in relation to the cutting plane by activating the adjustment device in order to correct the alignment of the cutting layer pressing against the feed saddle in relation to the cutting plane.
