## Abstract

A method for producing an analysis tape for fluid samples, in particular body fluids, is proposed. The method comprises providing a laminate tape having a laminate carrier tape and at least one diagnostic functional layer, and cutting the laminate tape in such a way that a diagnostic auxiliary label arises; transferring the diagnostic auxiliary label to a vacuum roller; and transferring the diagnostic auxiliary label to a carrier tape. In general, at least one vacuum roller is used for the transfer of the diagnostic auxiliary label to the carrier tape. The cutting of the diagnostic functional layer is effected in such a way that a free end of the diagnostic functional layer is lifted off from the laminate carrier tape by guiding the laminate carrier tape around a cutting edge with a small radius, wherein the diagnostic functional layer is cut at a predetermined distance from the lifted off free end by means of a cutting device.

## Claims

### Claim 1

A device for producing an analysis tape for fluid samples, the device comprising:
a laminate drive configured to supply a laminate tape having a laminate carrier tape and at least one diagnostic functional layer;
a cutting device configured to cut the diagnostic functional layer to form a diagnostic auxiliary label; and
a labelling device including
a cutting edge having a dispensing edge arranged adjacent the cutting device and configured to cause a free end of the diagnostic auxiliary label to lift off the laminate carrier tape,
at least one vacuum roller configured to receive the diagnostic auxiliary label from the cutting edge, and
a carrier drive configured to supply a carrier tape to the labelling device, the carrier drive and the vacuum roller are configured to interact so that the diagnostic auxiliary label is transferred from the vacuum roller to the carrier tape,
wherein the diagnostic functional layer is cut at a predetermined distance downstream from the lifted off free end by the cutting device.

### Claim 2 (depends on 1)

The device as claimed in claim 1 further comprising a vacuum roller drive for driving the vacuum roller, wherein the laminate drive, the carrier drive and the vacuum roller drive are synchronized.

### Claim 3 (depends on 1)

The device as claimed in claim 1, wherein the cutting device comprises a CO2 laser.

### Claim 4 (depends on 1)

The device as claimed in claim 1 further comprising a withdrawal device comprising an extraction device using suction, the withdrawal device configured to remove defective sections of the diagnostic functional layer before or after application to the vacuum roller.

### Claim 5 (depends on 1)

The device as claimed in claim 1 further comprising a defect identification device for identifying defective incipient cuts of at least one of the diagnostic functional layer and the laminate tape.

### Claim 6 (depends on 1)

The device as claimed in claim 1 further comprising a defect marking device for marking defective incipient cuts of at least one of the diagnostic functional layer and the laminate tape.

### Claim 7 (depends on 1)

The device as claimed in claim 1 further comprising in a region of the labelling device, a detection device for identifying incipient cuts of at least one of the diagnostic functional layer and the laminate tape which have been marked as defective.

### Claim 8 (depends on 1)

The device as claimed in claim 1, wherein at least one of the laminate carrier tape and the carrier tape is charged electrostatically.

### Claim 9 (depends on 1)

The device as claimed in claim 1, wherein the diagnostic auxiliary label comprises at least one diagnostic aid selected from the group consisting of a diagnostic test field with a test chemical designed to detect one or more analytes in the fluid sample; and a lancet designed to perforate part of a patient's skin to generate a fluid sample.

### Claim 10 (depends on 1)

The device as claimed in claim 1, wherein the at least one diagnostic auxiliary label is alternating lancets and diagnostic test fields.

### Claim 11 (depends on 2)

The device as claimed in claim 2, wherein the cutting device is synchronized with the laminate drive, the carrier drive and the vacuum roller drive.

### Claim 12 (depends on 1)

The device as claimed in claim 1, wherein the diagnostic functional layer includes defect markings for marking defective sections of the diagnostic functional layer, wherein sections marked as defective are removed before or after application to the vacuum roller.
