Abstract
A method and an apparatus for cutting woven labels. According to the invention, the woven labels, in the form of a continuous ribbon or the like, are fed step by step towards an ultrasonic wave cutting device, where each label is centered and pressed between a first cutting element defining the outline of the label and a second cutting element, aligned with the first, constituting an ultrasonic wave emitter; an ultrasonic impulse of adequate frequency and intensity, causes the cutting and simultaneous cold welding of the label all around the edges.
Claims2
A method for cutting woven labels from a ribbon of labels, said method comprising:
- feeding a ribbon of fabric labels woven from synthetic yarn to a cutting machine;
- guiding the labels to an ultrasonic wave cutting device;
- positioning each label between a first cutting element defining an ultrasonic wave emitter and, respectively, a second cutting element having a continuous closed cutting edge defining the outline of the label and having an opening within said closed cutting edge;
- pressing the label between the cutting elements and emitting an ultrasonic wave impulse, causing the simultaneous cutting of the label from the ribbon and the welding of the fabric around its cut edges;
- providing a tubular collector positioned below said second cutting element and in communication with said opening;
- and collecting said cut labels in said tubular collector.
