  • Patent number: 6306522
    Abstract: A lamella strip intended for further processing into a framework band with a U-shaped or V-shaped cross-section comprises lamellae (2) defined by separating cuts (1) which stand opposite one another in pairs, which lamellae are connected with one another via bridges (4). Each lamella (2) is divided by a center cut (6). Each lamella has two oblong bead-like stamp marks (7), which are arranged on both sides of the center cut (6), and end at a distance (A) from the edges (3) of the lamella strip, forming a smooth end region (8). To produce such a lamella strip, first the separating cuts (1) and center cuts (6) are made in a strip of sheet metal, before the bead-like stamp marks (7) are formed.
