High tenacity safety belts, as well as decorative braids, labels, woven suspenders, and belts must be woven in the specified width: full-width woven materials would unravel when cut into strips! Modern textile mills use computer-controlled "needle ribbon looms" to manufacture several — solid or patterned — bands at one time. On the "needle ribbon loom", the pick is placed through the shed as a thread loop. The loop is caught at the opposite edge of the ribbon by a bearded or latch needle and twists it into a stitch. In this way, up to 3000 "double picks" per minute are produced. The ribbon has a selvage and a looped edge.
