Abstract
Abstract This application discloses an apparatus and method for sonically welding a plurality of thermoplastic relatively flat members or plates. A sonic signal producing element or horn presses and imparts welding sonic signals to one of the flat members. A holding fixture holds one or more of such flat members. A base supports the holding fixture, and universal supporting joint means are provided between the holding fixture and the base. Such universal supporting joint means may include a relatively large spherical ball which is received in recesses in the holding fixture and in the base. This construction equally distributes the main part of the force of the horn over the entire surface of the parts to be welded together between the flat members or plates.
