A process and apparatus for the production of tapes and labels with smooth borders by means of ultrasonic cutting.

摘要

An ultrasonic cutting device is applied to a weaving machine (11) downstream of a templet (20) and downstream of the take-up beam (84) of the machine. The newly formed fabric (T) is passed through an ultrasonic cutting device (50) which cuts it longitudinally. Tapes with perfectly smooth borders are obtained; non-thermoweldable fibres can also be cut.
