To produce analyzing materials, especially test strips for fluid samples with an active capillary zone, a carrier layer (1) is prepared and a spacer layer (2) is laminated over one surface. A contour is cut, stamped or embossed from the laminated material to match the shape of the capillary-active zone (8), and any surplus spacer layer material is peeled away from the zone. A covering layer (11) is applied over the spacer layer to give the zone with an active capillary action. The spacer layer is a strip which is adhesive on both sides. The covering layer is in one or more parts, and is at least partially of an analysis indication film as described in P19629656.0. The spacer layer is laminated in place directly before the shape of the capillary active zone is cut. The removal of spacer layer material not required to form the capillary zone is directly after cutting. The carrier, spacer and the covering layers are prepared as ribbon materials. The contour is cut by a rotary cutting roller, in a continuous cut against a counter roller. After the covering layer has been applied, the strips are separated by cutting or stamping. |
