Method for manufacturing a seam connection between two textile sheet formations and ultrasonic welding device

摘要

A cover tape (17) is applied before welding onto the edge region of two subjects (11, 3) which are to be welded or bonded to one another by ultrasound. The cover tape (17) covers uncleanly cut edge regions (19), seals the seam and prevents the delamination with multi-layered material along the seam.
