Abstract
A barbed tape with a longitudinally extending strengthening groove is formed by pushing a strip of barbed tape to and through forming rolls which cooperate with the tape and a wire mandrel. The wire mandrel includes a continuous loop of wire rope which is guided to and through the forming rolls with the strip of barbed tape to form the longitudinal strengthening groove in the tape. The wire mandrel remains in cooperation with the tape as the grooved tape and wire mandrel move through a radial bender which bends the tape into a helical coil. The tape is provided in reel form and is fed to a blanking press to have barbs formed thereon prior to being fed to the roll former. A take up device receives the coiled tape as it exits the radial bender.
