Definitions

  • a second roll pair 25 is arranged at a spaced distance from the first roll pair along the tow path. This distance is preferably slightly less than the fiber lengths, so as to insure nipping between the ends of the fibers.
  • Debonding roll pair 25 is formed like first debonding roll pair 12 of substantially the same material and with substantially the same dimensions as heretofore given.
  • roll 22 has a helically threaded surface 23 and roll 24 is constructed like roll 20.
  • the lands of the flattened helical threads cooperate with the cushioned surface to form a fiber gripping portion or zone while the troughs or valleys between lands form a fiber passing zone as in the case with first debonding roll pair 12.
