A method and apparatus (20) for mechanically securing material (10), such as, for example, gasket or damping-type material for inhibiting or minimizing transfer of vibration or noise to sheetmetal (12) by punching, cutting, or otherwise creating one or more bendable metal flanges (14,16) in the sheetmetal (12) which project through and are bent or folded over and against the material (10) to thereby secure it in place. The apparatus (20) broadly comprises a punch (24) operable to create the flanges (14,16) by punching through the sheetmetal (12) , and an anvil (28) operable to bend or fold the flanges (14,16). The flanges (14,16) are preferably 1/10-½ inch in length and 1/10-¼ inch in width, and are provided with a curvature to facilitate bending.
