Abstract
Abstract This application discloses an apparatus and method for the sonic welding of one or more flexible or vibratable blades with a blade portion of each blade held by two or more plastic holding members with a free blade portion extending out of said plastic holding members. A vibration damping means is provided to dampen the vibratable blade free portion of each of such one or more blades to prevent crystallization and fatigue of said vibratable blade or blades while said plastic holding members are being sonically welded. The vibration damping means may include a damping pad carried by one sonic welding means or base and another damping pad carried by another sonic welding means or horn. The blade or blades may each have a second free portion extending from the plastic holding members in another direction, and such second free portion may be dampened by a third damping pad.
