ABSTRACT:
A manufacturing process and apparatus used to produce a container which is capable of accommodate an Hg source for a discharge lamp. The manufacturing includes producing a helical cutout in a coil former, inserting a flexible strip-like wire fabric into the helical cutout, automatically producing a coiled hollow-cylindrical strand at an outlet of the coil former by means of the strip-shaped wire fabric being moved through the helical cutout, and producing a coiled hollow-cylindrical container from the strand.
