Method for manufacturing valve device of airbag of motor vehicle, involves connecting textile layer with foil within region of foil by deep drawing tool, where region is different from deep-drawing region

摘要

The method involves arranging a textile layer (18) and a foil (14) in mutual overlapping areas in a deep drawing tool (10). The foil is deep-drawn within a deep-drawing region by the deep drawing tool such that multiple recesses are formed in the foil. The textile layer is connected with the foil within a region of the foil by the deep drawing tool, where the region is different from the deep-drawing region. The foil is punched by pneumatic positive pressure and/or positive pressure, and base elements are separated by a measurer, laser or a water jet.
