摘要
1. A device for an extruder for sheathing a core sensitive to the temperature of extrusion of the sheathing material consisting substantially of a tool comprising a tubular extrusion plate (1), an extrusion die (2) and a tubular guide (3), having a means (4) providing the possibility of cooling arranged so that its end abuts substantially in alignment with the outlet mouth of the tool forming the internal wall of the sheath, whilst leaving a channel (5) for a cooling medium between the said guide and the tool, which may reach as far as the outlet channel (6) of the material in the tool, characterized in that the end of the guide is terminated by a nozzle pierced by lateral holes.
