摘要:
A method and device for controlling the power intake of a welding unit (1) with an ultrasonic horn (2) and an anvil holder (3) equipped with anvils (4). The mean distance of the ultrasonic horn (2) from the anvil (4) is controlled so that the power intake of the welding unit (1) will coincide with a predetermined control value.
摘要:
The present invention relates to a method and apparatus for ultrasonic welding of material webs which move between at least one ultrasonic horn of an ultrasonic welding arrangement and an anvil holder having a determined pattern of anvils, so as to enable the webs to be welded at high web speeds. The weld width of each ultrasonic horn in the ultrasonic welding arrangement is determined in accordance with the intended highest travel speed of the webs.
