Theoretical investigations of continuous ultrasonic seam welding of thermoplastic polymers and fabrics

The article presents results of theoretical investigations of formation of continuous joint in contact area of flat surface of the radiator with rotating surface of the pressure roller. The recommendation on the choice of pressure roller parameters and optimal amplitude of ultrasonic vibrations and broach speed for materials different in properties and thickness were developed on the basis of analysis of distribution, reflection and absorption of ultrasonic vibrations in connected materials in the contact zone.
