METHOD FOR CREATING PREDETERMINED BREAKING LINE IN MULTI-LAYERED AIR BAG COVER USING LASER

摘要

The present invention relates to a method of forming a predetermined breaking line by using a laser to a multi-layer airbag cover comprising a carrier layer (1), a support layer (2), and a decorative layer (3). The present invention is configured to remove a carrier material with greater width than the diameter of the conflicting light beam in order to discharge combustion gas well for preventing combustion increasing unnecessary volume from the support layer (2) as a result of the generating combustion gas.
