Original document(13 pages)  中文版
    A band-shaped semi-finished product (1) 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 (2 and 3) are formed, between tips (2a and 3a) of which there remains a thin web (4) of material. The thin web (4) 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.
