Abstract
An apparatus (10) for applying an elastic material (14) to a backing material (18) includes an applicator assembly (12) for applying a length of elastic material (14) to a bonding template (16), and a bonding template (16) for supporting the length of elastic material (14) relative to the backing material (18) for a bonding operation. Ultrasonic horns (104,106) bond the length of elastic material (14) to the backing material (18). The applicator assembly (12) includes rolls (32,36) for tensioning the elastic material (14) and a vacuum mechanism for selectively retaining the length of tensioned material (14) and releasing the tensioned elastic material (14) to the bonding template (16). A mechanism is provided for transferring the tensioned elastic material (14) from the applicator assembly (12) to the bonding template (16) while maintaining the elastic material (14) in the tensioned condition.
