Abstract: A process of making ribbons which is carried out in a special machine that emits ultrasound, where the cloths, non-woven cloths, or any synthetic based surface accepting ultrasound welding, are cut in ribbons while markings are simultaneously applied to the ribbons' edge. The process of cutting cloths in strips (ribbons) and the process of marking the edges of the strips are done simultaneously on an ultrasound bar by a tool comprising a circular cutting knife, and by a rotating matrix heads with the desired marking drawings. If wire strings covered with synthetic textile substratum are to be applied to the ribbons, they are longitudinally applied along the mentioned ribbons by ultrasound welding and/or gluing process. These processes are carried out simultaneously to the cutting and marking processes of the ribbons, all happening in a single operation.
