Metal band as inlay for trim strips or sealing strips
View Patent ↗A metal band inlay for trim strips or sealing strips of flexible material that is bent to form a section. The metal band includes a plurality of edge slots in the longitudinal direction, which are guided inwardly from an edge of the metal band transversely to the longitudinal direction. The edge slots are wedge shaped. Central slots run to a tip toward their respective two ends and are arranged between the sequential edge slots. The central slots extend transversely to the longitudinal direction, but do not extend up to the edge. To simplify the cutting, the metal band further includes throughcuts that extend transversely to the longitudinal direction of the metal band, that correspond to at least some of the central slots and that extend from at least one edge of the metal band in the direction toward the tip of the respective central slot disposed opposite to the edge.
1. A metal band inlay for trim strips or sealing strips of flexible material that is bent to form a section, the metal band having a plurality of edge slots in a longitudinal direction, the edge slots are guided inwardly from an edge of the metal band transversely to the longitudinal direction and are wedge-shaped, and central slots, that run to a tip at respective two ends, are arranged between sequential edge slots and likewise extend transversely to the longitudinal direction of the metal band, but are not guided up to the edge, wherein the metal band also includes throughcuts that extend transversely to the longitudinal direction of the metal band and between two successive edge slots that correspond to at least some of the central slots and that extend from at least one edge of the metal band in the direction toward the tip of the respective central slot disposed opposite to the edge wherein a short, non-throughcut region is present between an inner end of the throughcuts and the respective oppositely disposed tip of the central slots.
2. A metal band in accordance with claim 1 , wherein the throughcuts are provided to correspond with each central slot.
3. A metal band in accordance with claim 1 , wherein the throughcuts are provided along both edges.
4. A metal band in accordance with claim 1 , wherein the non-throughcut region has a length of less than 0.5 cm.
5. A metal band in accordance with claim 1 , wherein the edge slots are arranged in pairs in that two respective edge slots are inwardly guided from the two edges of the metal band and are disposed opposite to one another.
6. A metal band in accordance with claim 1 , wherein the central slots are arranged symmetrically to a central longitudinal axis of the metal band.
7. A metal band in accordance with claim 6 , wherein the central slots have a length such that, with a section bent into U shape, they extend up to and into a limb.
8. A metal band in accordance with claim 7 , wherein the central slots each only extend into the limb a distance that is shorter than their length.
9. A metal band in accordance with claim 1 , wherein the central slots are arranged symmetrically to an axis that is parallel to the central longitudinal axis of the metal band.
10. A metal band in accordance with claim 9 , wherein the central slots only extend into one limb of the section.
11. A metal band in accordance with claim 1 , wherein the edge slots and the central slots are made to overlap one another in the transverse direction of the metal band.
12. A metal band in accordance with claim 11 , wherein the edge slots and the central slots overlap one another by substantially a twelfth of the width of the metal band.
13. A metal band in accordance with claim 1 , wherein the edge slots and the central slots are cut and are widened by stretch rolling.
14. A metal band in accordance with claim 1 , wherein the throughcuts are not widened.
