A fastener includes a sleeve and a rod received in the sleeve. A detachable and reversible dual visor with first and second opposing major surfaces can also be attached to the reversible crown. By avoiding the need for subsequent verification after the cell has reached its desired threshold level, read disturbs may be reduced in some embodiments. The retained portion of the mold provides mechanical support for any adjoining layer or layers. The automated placements of these deliveries of the fiber bundletow at selected orientations in the area correspond to the feeding zone of an improved circular loom bed plate turntable.
