ABSTRACT:
A band-shaped semi-finished product is made out of a ductile material and is configured to be separated into at least two sections. At least one pair of wedge-shaped, non-cuttingly formed longitudinal notches are formed, between the tips of which there remains a thin web of material, which can be torn easily with little force. The semi-finished product is distinguished by burr-free separated edges, defined geometry of the separating surfaces, and extremely reduced breaking-surface portions. It shows improved resistance during static and dynamic stress, in particular for alternating bending loads, in comparison to conventional, for example via the rolling-cutting technique, separated semi-finished products.
