Abstract
The invention concerns a method for the constant maintenance of the mean gap width between a sonotrode of an ultrasonic system and a tool of an ultrasonic cutting device, designed as a counter surface, for cutting and/or welding of various types of materials such as, for example, synthetic foils, textile fabrics containing synthetic substances, by means of a cutting tool, using an adjusting device.
Claims15
A method for maintaining a mean gap between a sonotrode of an ultrasonic system and a tool of an ultrasonic cutting device, comprising
- by way of a control system, maintaining a constant clearance between the sonotrode and at least one counter surface comprising
- maintaining a constant contact time between the sonotrode and the at least one contacting surface.
A method of maintaining a constant mean gap between a sonotrode in an ultrasonic system and a counter surface in an ultrasonic cutting device, said method comprising:
- providing a set-time;
- measuring a contact time between the sonotrode and a contact surface;
- and
- adjusting the contact time to the pre-set time when the contact time is different than the set-time.
