Abstract
A method and a device for producing filter inserts (1), in particular filter inserts (1) for preparing a coffee or tea filtrate, including the continuous folding (A) of a filter paper sheet (2) into a double layer (3), partially binding (B) the double layer (3) to a plurality of interconnected filter inserts (1) using at least one stamped seam (4) and separating (D) the interconnected filter inserts (1) from the filter paper sheet (2). The filter inserts (1) are provided with a label (5) after folding (A).

Method for producing filter inserts comprising the steps of:
- continuously folding a filter paper sheet into a double layer,
- partially binding the double layer into a plurality of interconnected filter inserts using at least one stamped seam, and
- separating the interconnected filter inserts from the filter paper sheet, and
- stamping the filter inserts with an elastic punch and a counterpunch, the counterpunch producing a label stamped into the filter inserts and the elastic punch acting to prevent the double layer of the folded filter paper sheet from being bound to one another by the label stamped into the filter inserts,
- wherein labeling of the filter insert occurs simultaneously with the separation of the filter insert from the filter paper sheet.

- stamping the filter inserts with a punch and elastic counterpunch, the punch producing a label stamped into the filter inserts and the elastic counterpunch acting to prevent the double layer of the folded filter paper sheet from being bound to one another by the label stamped into the filter inserts,
- wherein the stamping of the label reaches both layers of the double layer so that a part of the label is arranged on both sides of the filter insert,
- wherein the stamping of the stamped seam of both layers of the filter and stamping of the label occur in one step with a single stamping roller or pair of stamping rollers.
