(57) An apparatus particularly for manufacturing electrical cables with a sheathing made
of silicone rubber and the like, comprising a catalysis oven (11), which in turn comprises
a tank for containing molten salts, which has a predominantly longitudinal extension
and has mutually opposite access openings; means (12a,12b) for unwinding a conductor
from a reel, means (13a,13b) for extruding insulating material onto the conductor,
means (14a,14b) for tensioning the outgoing cable, and means (15a,15b) for winding
the cable onto a reel being functionally arranged upstream and downstream of each
one of the access openings in order to make two cables (16,17) being treated slide
with a longitudinal orientation and opposite directions.
