Expanded metal for automotive interior parts

An expanded metal produced by repeated penetration of a movable cutting die including teeth into a metal sheet that is run through an expansion device in a feed direction, the expanded metal comprising:

• a plurality of loops, each having an identical number of vertices,
• wherein the loops include bars that envelop loop openings and that are connected in nodes,
• wherein each of the loops includes a loop opening length measured in the feed direction along a line from a node center to another node center of two nodes that are arranged adjacent to one another in columns that extend parallel to the feed direction,
• wherein each of the loops includes a loop opening width measured transversal to the feed direction along a line from a node center to a node center of two nodes that are arranged adjacent to each other transversal to the feed direction,
• wherein the loops are arranged adjacent to one another in rows that extend transversal to the feed direction,
• wherein the loop opening length of loops arranged adjacent to one another in the columns varies in the feed direction along a longitudinal section of the expanded metal, wherein the loop opening length of loops arranged adjacent to each other in the rows is constant,
• wherein the loop opening width of the loops arranged adjacent to one another in the columns in the feed direction varies in the feed direction along a longitudinal section of the expanded metal wherein the loop opening width of the loops that are arranged adjacent to each other in the rows is constant,
• wherein the loop opening width or the loop opening length of the loops that are arranged in the columns adjacent one another in the feed direction varies from row to row, and
• wherein differences in the loop opening width and the loop opening length from row to row are sized so that the loop opening width and the loop opening length change continuously from row to row, and wherein the number of vertices is three.
