  • Patent number: 7455743
    Abstract: A method of forming a stitchless, adhesively bonded seam involves placing a first strip of adhesive between the outside surface of first and second sheets of material along an edge of the second sheet. At least a portion of a second strip of adhesive is positioned against a first portion of the inside surface of the second sheet along the edge thereof. The second sheet of material is folded such that a second portion of the inside surface overlies the second strip of adhesive. In some embodiments the first and second strips of adhesive are replaced by a single longitudinally folded strip of adhesive. Energy may be applied, via an ultrasonic seam bonding machine or other means, to activate the adhesive. Seams made according to the disclosed methods may be used for garments, sports articles, and other items made of fabric or other sheet material.

  • Publication number: 20080223502
    Abstract: This invention provides a manufacturing method of printed wiring board which enables a plate-like substrate to be carried and processed without any contact to its product surface. End portions of plate-like copper clad laminates are overlapped vertically and then joined linearly by rotating an ultrasonic horn along the end portions. Consequently, copper foils can be metal-joined and a joining strength necessary for transportation with a roller is obtained. Because belt-like copper clad laminate is obtained by joining the plate-like copper clad laminates and after that, processed, thus, the belt-like copper clad laminate can be carried without any contact to its product surface as it is carried with the roller, and then processed.

    Abstract: A method for assembling at least two rigid thermoplastic material based parts. The two parts are superposed to have at least one interface zone, wherein at least one of the two parts includes one or plural energy directors, protruding, situated in the interface zone. At least one excited ultrasonic source is brought into contact with one of the two parts, the ultrasonic source applying a compression effort to the two parts in a region of the interface zone located opposite the ultrasonic source. The ultrasonic source is continuously displaced at the interface zone to form a continuous welded joint by fusion of the thermoplastic material in the region positioned opposite the ultrasonic source. Such a method may find particular application for assembly of stratified parts.

  • Patent number: 6818098
    Abstract: After the fixing of an angle indexing body to a holder by fixtures is canceled by loosening the fixtures, a resonator is turned by operating the angle indexing body with an axis in a vibration transmission direction as the center of rotation, a bonding work face is replaced by another bonding work face, and the angle indexing body is fixed to the holder by the fixtures so that the new bonding work face becomes parallel to the top face of a mounting table. Therefore, the replacement of the bonding work face can be simplified. Since overlapped workpieces are sandwiched between the bonding work face of the resonator and the mounting table, the mounting table makes a follow-up movement by a bearing composed of a spherical projection portion and a spherical depression portion to ensure that the bonding work face becomes parallel to the top face of the mounting table, thereby making it possible to optimize the position of the sandwiched workpieces.
