An apparatus for extruding pencils and a method of using the apparatus. A core material (6) is extruded from an extruder (1) and forms a catenary loop in a cooling zone (4). The core material is carefully cooled at ambient temperature before being cooled and straightened at a cooling unit (5). The core material is coated in a crosshead and die assembly (8) with sheath material extruded from extruder (10). In a further cooling zone (12) the sheath material expands under the action of a blowing agent and the extrudate is sized by a calibrator (13). <IMAGE> |
