A method for joining several material layers of synthetic knitted fabric or woven fabric, in particular application of motifs to flags, banners, pennants and the like, and the use of an ultrasonic welding device, as well as such a knitted fabric or woven fabric itself

摘要

The invention relates to a process for combining a plurality of layers (16, 18) of synthetic knitted or woven fabric, in particular for the application of motifs on flags, banners, pennants and the like. The production of flags, banners, pennants and the like provided with a motif is relatively complex in the state of the art and leads to high costs since the extent of the manual operations is considerable. The invention provides a remedy for this by employing an ultrasonic welding device with CNC control of its sonotrode (15). IMAGE
