Abstract
Gang-ripping technology that uses a movable (floating) outer blade to eliminate unusable edgings is described, including new tenn1nology for identifying preferred and minimally acceptable strip widths. Because of the large amount of salvage required to achieve total yields, floating blade gang ripping is not recommended for boards with crook. With crook removed by crosscutting to shorter, straight pieces, fixed arbor and floating blade procedures gave similar yield results. The yields from several hundred straight boards were also similar to those for the boards with crook removed. No.1 Common had more yield in the longest lengths than did No.2 Common, but the amount of No.2 Common lengths had been shown earlier to be more than sufficient to meet the needs of the furniture and cabinet industries.
