    Chain flail delimber-debarkers have gained a degree of acceptance in the Southern USA, especially for processing thinnings from pine plantations. TIzis Technical Release compares the quality of chips produced by in-woods chippers teamed with chain flail delimber-debarkers, with chips produced in conventional large-scale woodyards, to be a guideline as to what may occur with similar processing of radiata pine in New Zealand Pine chips from the chain flail and in-woods disc chipper compared favourably with pine chips produced ffom drum debarker and disc chippers in woodyards. These in-woods chips were similar in bark content and in the production of chips of an acceptable size. The flails, however, were less effective in debarking hardwood stems than were the drums in the woodyards.
