1. An apparatus for through thickness reinforcement of a fibrous preform, the apparatus comprising:
an actuating needle board including a plurality of textile needles extending therefrom;
a feeder spool configured to supply a veil cloth;
a take up spool configured to receive the veil cloth;
a first roller;
a second roller;
a first stripper plate configured to be disposed between the veil cloth and the fibrous preform, the first stripper plate is configured to space apart the veil cloth from the fibrous preform to aid in complete through thickness fiber separation from the veil cloth prior to insertion of the through thickness fiber into the fibrous preform;
a third roller mounted to the first stripper plate; and
a fourth roller mounted to the first stripper plate;
wherein the first roller is configured to guide the veil cloth from the feeder spool to the second roller, and the second roller is configured to guide the veil cloth from the first roller to the take up spool, and
the actuating needle board is configured to move with respect to the first roller and the second roller between a retracted position and an extended position for moving through thickness fibers from the veil cloth to the fibrous preform.
