ABSTRACT:
An apparatus (10) of the type for laminating two elastomeric fibrous web materials (14,16) together by ultrasonic bonding includes a continuously moving web transport support (12) for transporting at least two overlaid webs (14,16) through the apparatus (10). An ultrasonic horn (18) transmits ultrasonic energy to bond the webs (14,16) together into a laminate. An anvil underlies the ultrasonic horn (18). A vacuum mechanism (24) draws the webs (14,16) against the web transport support (12) for perfecting bonding and to prevent rippling and tearing of the webs (14,16) against the horn (18) and the web transport support (12) during the ultrasonic bonding.
