摘要

The invention relates to a cross seam joining device for a flexible packaging having at least one ultrasonic applicator (13a - 13c), which is rotatably mounted on a shaft (13d) and can be rotated about an axis (13e) of the shaft (13d) arranged longitudinally to the cross seam (110, 111). The ultrasonic applicator (13a - 13c) is designed to produce and bundle ultrasounds in a frequency range of 0,1 MHz - 0, 5 MHz, preferably from 0,5 MHz - 2 MHz.
