Abstract

A process for the production of at least one analytical device is disclosed. The analytical device comprises at least one capillary element. The process comprises providing at least one carrier layer; providing at least one spacer layer; applying the spacer layer on top of the carrier layer; providing at least one cover layer; and applying the cover layer on top of the spacer layer. The process further comprises at least one cutting step. At least one capillary channel of the capillary element is cut out from the spacer layer. The cutting step is performed by using at least two cutting tools. The cutting tools complement one another to form a contour of the capillary channel.

First claim

We claim:

1. A process for the production of at least one analytical device, the analytical device having at least one capillary element, the process comprising:
providing at least one carrier layer;
providing at least one spacer layer;
applying the spacer layer on top of the carrier layer;
providing at least one cover layer;
applying the cover layer on top of the spacer layer; and cutting out at least one capillary channel of the capillary element from the spacer layer, wherein the cutting out is performed by using at least two cutting tools, wherein each cutting tool generates a cutting line that overlap and complementing one another to form a contour of the capillary channel and an overlapping region, wherein the overlapping region compensates for varying distances between the cutting lines, wherein the cutting tools are individually controlled with regard to at least one cutting parameter.

2. The process according to claim 1 , wherein the cutting tools comprise at least one cutting cylinder having at least one cutting edge.

3. The process according to claim 2 , wherein the cutting tools further comprise at least one counter cylinder interacting with the cutting cylinder.

4. The process according to claim 2 , wherein the cutting cylinder comprises a plurality of cutting edges located on a circumferential surface of the cutting cylinder.

5. The process according to claim 4 , wherein the cutting edges are S-shaped.

6. The process according to claim 2 , wherein the cutting edges of the at least two cutting tools have a mirror symmetry.

7. The process according to claim 1 , wherein the cutting out is at least partially performed before applying the spacer layer on top of the carrier layer, wherein, during the cutting out, the spacer layer is located on top of at least one support tape, wherein, after the cutting out, the support tape is removed and the spacer layer is applied on top of the carrier layer.

8. The process according to claim 1 , wherein at least one cutting line is generated within the spacer layer.

9. The process according to claim 1 , wherein the process further comprises,
at least one singulation, wherein the analytical devices are cut from a web containing the carrier layer, the spacer layer and the cover layer.

10. The process according to claim 1 , wherein the capillary channel comprises at least two side walls, wherein the side walls are produced during the cutting, wherein at least a first one of the side walls is produced by a first cutting tool, and wherein at least a second one of the side walls is produced by a second cutting tool.

11. The process according to claim 1 , wherein the cutting is performed in a position-controlled fashion by using one or both of carrier layer positioning marks within the carrier layer and spacer layer positioning marks within the spacer layer.

12. The process according to claim 1 , wherein, in the cutting, an inner part of the capillary channel is separated from a remainder of the spacer layer, wherein the inner part is removed from the carrier layer.

13. The process according to claim 1 , wherein the cover layer comprises an analytical detection film.
