0875489-A1 is referenced by 8 patents and cites 3 patents.

A method is claimed for the fabrication of glass fibre preforms. The method consists of rotating a preformer (10) around its axis (12), displacing it in translation relative to a plasma blowtorch (14), in a direction parallel to the axis (12) of the preformer, the axes (20) of the flame (18) and (12) of the preformer being staggered by a certain distance (x), and the introduction of a glass powder by gravity into the plasma flame (18). The glass powder is accelerated, before it has penetrated into the plasma flame (18), by an accelerator gas, and the distance (x) of the stagger of the axes (12, 20) is reduced whilst the acceleration of the powder is increased. The apparatus used to put this method into service is also claimed.
