1. Apparatus for forming fiber reinforced composite material tape in the general plane of the tape, comprising:

  • restraint means for exerting pressure on the tape in a thicknesswise direction perpendicular to said plane to confine the tape to an elongated space during forming of the tape in the general plane of the tape, to confine the tape to said general plane and thereby prevent buckling and wrinkling of the tape;

    said restraint means including portions that define the thickness of said space and that are flexible in a widthwise direction perpendicular to said thicknesswise direction; and

    bending means for exerting a force on said portions in said widthwise direction, to bend said portions and said space and any tape confined therein in said widthwise direction, to form said space and said tape confined therein into a predetermined planform configuration without changing the width and thickness of the space and the width and thickness of the tape.
