Abstract
An apparatus for segmenting and feeding a fiber includes at least one capillary having a lumen therethrough configured to deliver a fiber segment. An advancing advances a fiber through the capillary. Tensioning means applies tension to the fiber to induce it to break. Damaging means locally damages the fiber.
Claims12
An apparatus for segmenting and feeding a fiber comprising:
- a nozzle comprising a tapered distal tip;
- at least one capillary positioned coaxially within the nozzle, the at least one capillary having a lumen therethrough configured to deliver a fiber segment, the at least one capillary comprising a slot at the tapered distal tip;
- advancing means for advancing a fiber through the capillary;
- tensioning means for applying tension to the fiber to induce the fiber to break;
- and
- damaging means for localized damaging of the fiber, the damaging means positioned within the slot, the damaging means configured to cut the fiber in response to the at least one capillary translating axially against the tapered distal tip.
