    Description

    In previous research on the process for making groundwood in a double-disk refiner, a theoretical stress analysis indicated that tracheids of Pinus taeda L. may fail while under torsional stress and unwind into ribbonlike elements. Such elements provide the coherence necessary for strength development in these pulps. Depending upon their physical state, tracheids may also buckle or shear and yield no ribbons.
