Embodiment Construction
[0054] [54] FIGS. 1 to 4 show the different steps of the assembly method given in accordance with the first embodiment of the present invention by means of an ultrasonic fusion machine 1 .
[0055] [55] Such machines are known, for example, from patent US 3,817,802 and will therefore not be described in detail. The machine comprises: a frame 10 supporting the ultrasonic motor or vibrator 12 ; a support plate 11 for objects 14 to be fused; and a fusion device 13 .
[0056] [56] There are also other ultrasonic fusion machines in which, at a pressure of a few bars, the elements to be fused are advanced between two rotating fusion tools, which can accomplish the assembly in the form of a sewing machine.
[0057] [57] In the principle of ultrasonic fusion, vibrations with a frequency between 20 and 30 KHz are applied to the fusion tool by the vibrator. The vibrations heat the two layers of the material to be assembled and cause them to fuse to each other.
[0058] [58] Of course,...
