The invention relates to an embossing tool, are embossed with the tactile detectable structures in a substrate. According to the invention, the embossing tool has a corrugation in a first edge region of the embossing tool on the front side and a corrugation in a second edge region of the embossing tool on the back side of the embossing tool, wherein the first and the second edge region lie opposite one another on the embossing tool and engage in subsequent clamping of the embossing tool Embossing tool overlap on a stamping cylinder and the corrugation of the first edge region with the corrugation of the second edge region interlocks. The second edge region is bent or bent backwards by about 180 ° so that the corrugation is arranged on the rear side of the embossing tool.;Alternatively, the embossing tool has a corrugation in a first edge region of the embossing tool on the back of the embossing tool and a corrugation in a second edge region of the embossing tool on the back of the embossing tool. Thus, both edge regions have a corrugation on the back of the embossing tool. The first and the second edge region lie opposite one another on the embossing tool and engage in a subsequent clamping of the embossing tool on an embossing cylinder with a corrugation on the embossing cylinder. The first and second edge portions are bent or bent rearwardly by about 180 degrees so that the corrugations originally located on the front side of the stamping tool are located on the back of the stamping tool.
