A method for dispensing discrete length reinforcement fibers (14). A continuous length of a reinforcement fiber (30) is wound around a base end (36) of a form (34), the base end (36) having a generally circular crosssection, to form generally circular coils (38). The coils (38) are moved axially from the base end (36) of the form (34) to an elongated portion (62) of the form (34), the elongated portion (62) having an elongated crosssection, to change the shape of the coils (38) from the generally circular shape to an elongated shape. The elongated coils (38) are cut to form discrete length reinforcement fibers (14). The discrete length reinforcement fibers (14) are then dispensed.

Why it's free to use
- Filed September 3, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 3, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 3, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
