A method and apparatus for applying a fastener having a body member (12) and a rivet member (14) to a compliant sheet material (18) includes anti-pucker apertured member (48) having an opening (52) therein coaxially aligned with first and second tool members (42,40). The inner peripheral wall (54) of the apertured member is of substantially the same cross-sectional configuration as the body of the fastener, the opening of the apertured member being of a size large enough to accept the body of the fastener with the upper portion of the inner peripheral wall of the opening (52) adapted to cooperate with the outer peripheral surface (32) of the body of the fastener to capture the material therebetween the stretch the material taut over the bottom end (34) of the body of the fastener such that a post member (16) can pierce the material and be received within a recess (20) in the bottom end of the body without wrinkling or puckering the material. |
