Abstract

The invention is an extrusion apparatus and a method for extruding fibres. The extrusion apparatus has a first tubular passage (17) through which a core material (25) is extrudable. The tubular passage (17) has a first exit opening (13). In operation, the core material (25) is drawn down at a first distance at least 0.5 mm from the outer exit opening (13) within the first tubular passage (17). In another embodiment of the invention, the extrusion apparatus is provided with a second tubular passage (50) through which a coating material (27) is extrudable. The second tubular passage is disposed about the first tubular passage (17) and has an inner opening (52). The inner opening (52) is within the second tubular passage (50) and, in operation, coating material (27) is drawn down within the second tubular passage (50).
