ABSTRACT:
The device and process allow for continuous processing of metal wire sheathed in glass (10) of considerable length.Normally a feed pipe (15) containing all the necessary metal, itself placed into a glass tube (20), so as to continuously supply a bead (14) to the lower part of the glass tube (20). Heat from a first inductor (23) around the glass tube (20) and a second inductor (24) under the glass tube (20) allow to maintain a bead (14) at a stable temperature and in a continuous manner and to obtain the continuous drawing process of a metal wire sheathed in glass (10).
