Abstract:
The inventive method of forming anchors comprises following steps. A rod-shaped workpiece is roll-formed by penetrating the rod-shaped workpiece with two wedge-shaped tools at two points. The two points are arranged on opposite sides and axially separated of a plane perpendicular to an axis of the rod-shaped workpiece. The two wedge-shaped tools are axially approaching to the plane while the rod-shaped workpiece is revolved around the axis. The roll-formed workpiece is separated along the plane for forming two bolts. A sleeve is applied around the anchor bolts.
