Obtaining airbag tube with charging head by cold forming, comprises beveling extremity of tube, reduction of tube diameter until reaching constant diameter, angular deformations, bending and flattening free extremity or tip of final length

摘要

Airbag tube with cold worked charge header and the procedure for obtaining it. The airbag tube is obtained according to the following operational stages: bevelling of one of the ends of a cylindrical tube, reduction of the external diameter of the tube, in the end section (2) of its length, a first angular deformation of the end section (2), a second angular deformation of the end section (2), curving of the tip of the end section (2) and flattening of the tip of the end section (2) in order to obtain a flat section with a central hole (3) for attaching the loading nozzle.
