Abstract
A metallic card wire has an elongated rib portion and teeth. The teeth have a front segment, a top segment and a back segment. The front segment has the connection of the tooth from the elongated rib portion and the front segment including a tip which is actively taking fibers in carding. The top segment has at least one hunch after the tip in the direction of the back segment. If more than one hunch is present the first hunch is the hunch positioned closest to the tip; if only one hunch is present this hunch is the first hunch. The back segment forms the connection of the top segment towards the elongated rib portion and the front segment of the next tooth.
