摘要

The procedure for producing an adhesive surface (100) having an internal area (101) and a border area (102) on a surface of a die carrier (200) for the successive fastening of dies on the adhesive surface, comprises pressing a self-hardenable adhesion adjusted under thixotropic with increased surface tension by a pattern pressing process on the surface of the carrier, collecting a pattern and producing the adhesive surface, whose border area is elevatedly formed relative to the internal area. A convex-shape is formed during a pre-determined resting time. The procedure for producing an adhesive surface (100) having an internal area (101) and a border area (102) on a surface of a die carrier (200) for the successive fastening of dies on the adhesive surface, comprises pressing a self-hardenable adhesion adjusted under thixotropic with increased surface tension by a pattern pressing process on the surface of the carrier, collecting a pattern and producing the adhesive surface, whose border area is elevatedly formed relative to the internal area. A convex-shape is formed during a pre-determined resting time after pressing the surface of the pressed adhesive surface under the influence of the increased surface tension. The resting time is adjusted for developing the convex-shaped surface by a layer thickness of the pressed adhesion relative to the size of the adhesive surface. The pressed adhesive surface is exposed during the resting time of the increased temperature. The carrier with the pressed adhesive surface is stored during the resting time in a gas. Two adhesive surfaces are produced for the die. The pressed adhesive surface is formed by a recess (502) formed in the squeegee edges of the doctor blades in the internal area as in the lateral border area. The internal area has a large layer thickness. The recess is formed in the form of rectangular, trapezoid and/or circular sections. The recess corners are rounded off. The recess of a narrow handing slot is formed deeply into the blades. The internal area of the adhesive surface is formed by two lateral border areas bounded eccentrically to the adhesive surface. The adhesion pressed on the carrier is fastened after the formation of the large layer thickness in the internal area by a first hardening step in a self-hardened condition at 100[deg] C with a duration of 60 min.
