Abstract

A method for splitting a semi-finished product includes placement of the semi-finished product on a splitting template, and the splitting template includes at least one elevation. The method includes fixation of the semi-finished product on the splitting template, in which an area of the semi-finished product is arranged on the elevation. The method includes splitting of the semi-finished product, in which material is removed from the semi-finished product during splitting. The material removal in the area that is arranged on the elevation is greater than in an area that is not arranged on the elevation.

Claims (14)

1 . A method for splitting a semi-finished product, the method comprising:

placing the semi-finished product on a first surface of the splitting template, the splitting template including at least one elevation that protrudes above the first surface of the splitting template;

fixing the semi-finished product on the splitting template, with a first area of the semi-finished product arranged on the at least one elevation and at least one second area of the semi-finished product not arranged on the at least one elevation, the at least one second area including a fixing tab; and

splitting the semi-finished product, with material removed from the first area of the semi-finished product during splitting and no material removed from the semi-finished product in the at least one second area, and the material removal in the first area that is arranged on the at least one elevation is greater than in the at least one second area that is not arranged on the at least one elevation.

2 . The method according to claim 1 , wherein the at least one elevation reproduces an outer contour of the semi-finished product.

3 . The method according to claim 1 , wherein the at least one elevation causes the semi-finished product to have a first material thickness after the splitting in the first area which was arranged on the at least one elevation during the splitting, and the first area with the first material thickness is arranged between two of the at least one second area of the semi-finished product having a second material thickness after the splitting, wherein the first material thickness is smaller than the second material thickness.

4 . The method according to claim 1 , wherein the semi-finished product and the splitting template are moved relative to a splitting tool in a feed direction during the splitting.

5 . The method according to claim 1 , wherein a splitting tool is moved relative to the semi-finished product and the splitting template in a feed direction during splitting.

6 . The method according to claim 1 , wherein the splitting template has the first surface and a second surface opposite the first surface, wherein a vertical distance between the first surface and the second surface inside the at least one elevation is greater than a perpendicular distance between the first surface and the second surface outside of the at least one elevation.

7 . The method according to claim 6 , wherein the vertical distance between the first surface and the second surface varies inside the at least one elevation, and the semi-finished product has various material thicknesses after splitting in the first area which was arranged on the at least one elevation during splitting.

8 . The method according to claim 6 , wherein the second surface of the splitting template is parallel to an imaginary splitting plane during the splitting.

9 . The method according to claim 1 , wherein the semi-finished product and the splitting template are removably fixed to each other via an adhesive.

10 . The method according to claim 1 , wherein the semi-finished product comprises leather.

11 . The method according to claim 1 , wherein the splitting template comprises silicone.
