Ultrasonic device for welding and cutting natural, synthetic or mixed fabrics, comprising an ultrasound converter which is operatively coupled to a sonotrode which is constituted by a tool, one end of which cooperates with a working surface and has a welding region and a cutter which is connected to the welding region downstream with respect to the direction of advancement of the material to be welded. Means are provided for the orientatable support of the tool so that the cutter has one end in contact with the working surface and the welding region is raised with respect to the working surface, so as to provide a guide for the insertion of the material to be welded beneath said region and allow the welding of the material along a band whose width corresponds to the width of the welding region and the cutting of the band so as to produce two adjacent welded edges. <IMAGE> |
