摘要

The invention relates to a method for producing a vehicle interior trim part having a decorative layer (4) and a decorative element (3) fastened on the visible side of the decorative layer (4) and / or in a depression of the visible side of the decorative layer (4), wherein - the decorative layer (4 ) and the decorative element (3) on a tool (2) are arranged such that the decorative element (3) on the visible side of the decorative layer (4) or in the recess of the visible side of the decorative layer (4) is arranged, - an ultrasonic sonotrode ( 5) in the direction of the tool (2) is moved, wherein the ultrasonic sonotrode (2) comes into contact with the decorative layer and after touching the decorative layer (4) is moved further in the direction of the tool, wherein in the region of the decorative element (3) the decorative layer (4) at least partially softened by ultrasound being introduced into the decorative layer (4) so that the decorative element (3) is fastened to the decorative layer (4) by means of an ultrasonic weld t will. According to the invention, a distance (14) of the ultrasound sonotrode (5) from the tool (2) or a predetermined point of the tool (2) is determined by determining an electrical parameter using a measuring point (17) and / or sensor (17) attached to the tool (2). 10).
