Yield comparisons from floating blade and fixed arbor gang ripsaws when processing boards before and after crook removal

Gang-ripping technology that uses a movable (floating) outer blade to eliminate unusable edgings is described, including new terminology 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 cross-cutting 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. I 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.
