Abstract
A method for dispensing discrete length reinforcement fibers. A continuous length of a reinforcement fiber is wound around a base end of a form, the base end having a generally circular cross-section, to form generally circular coils. The coils are moved axially from the base end of the form to an elongated portion of the form, the elongated portion having an elongated cross-section, to change the shape of the coils from the generally circular shape to an elongated shape. The elongated coils are cut to form discrete length reinforcement fibers. The discrete length reinforcement fibers are then dispensed.

A method for dispensing discrete length reinforcement fibers comprising the steps of:
- winding a continuous length of a reinforcement fiber around a base end of a form, the base end having a generally circular cross-section, to form generally circular coils, the form having a longitudinal axis;
- moving the coils axially from the base end of the form to an elongated portion of the form, the elongated portion having an elongated cross-section, the coils being moved on a generally smooth exterior surface of the form which changes gradually from the generally circular cross-section to the elongated cross-section, to gradually change the shape of the coils from the generally circular shape to the elongated shape;
- cutting the elongated coils to form discrete length reinforcement fibers;
- and
- dispensing the discrete length reinforcement fibers.
A method for dispensing discrete length reinforcement fibers comprising the steps of:
- winding a continuous length of a reinforcement fiber around a base end of a form, the base end having a generally circular cross-section, at a winding speed which is at least about 10% greater than a winding speed around a form having an elongated cross-section with the same peripheral length as the base end, to form generally circular coils, the form having a longitudinal axis;
- moving the coils axially from the base end of the form to an elongated portion of the form, the elongated portion having an elongated cross-section, the coils being moved on a generally smooth exterior surface of the form which changes gradually from the generally circular cross-section to the elongated cross-section, to gradually change the shape of the coils from the generally circular shape to the elongated shape;
- cutting the elongated coils to form discrete length reinforcement fibers;
- and
- dispensing the discrete length reinforcement fibers generally parallel to each other.
