Abstract
Official abstract text for this publication.
A filter medium is embossed to form embossments and the filter medium is then cut at least in some sections by a cutting device such as a water jet, a laser beam, an ultrasonic cutting device, or a cutter, by moving a point of impact of the cutting device relative to the filter medium to produce a cutting line. After cutting, the filter medium is folded. Alternatively, the filter medium is folded to folds and then at least some of the folds are pulled apart at least partially. In a region of the folds which have been pulled apart, the filter medium is cut at least in some sections thereof by the cutting device by moving a point of impact of the cutting device relative to the filter medium to produce a cutting line. After cutting, the folds are reset.
