Title: Extruder die head
Inventor: BECKMANN HANS-UDO
IPC: B29C48/30
Filed: 2001-01-09
Abstract: An extruder die head, such as a blown film head, comprises an internal cylindrical mandrel and an outer concentric jacket enveloping the mandrel to provide an annular channel that communicates with a die slit. To avoid slit-like gaps between the mandrel and the jacket, where polymer melt can accumulate and degrade resulting in flaws in the extruded polymer, the mandrel has an integral outwardly extending flange-like foot. At least one supply line for molten polymer, such as a set of boreholes communicating with helical grooves in the outer cylindrical face of the mandrel, is connected to the annular channel in the area adjacent the flange-like foot. A ring is shrunk onto the mandrel against the foot, at a predetermined tension to seal the slit between the mandrel and the jacket, and avoid the effects of differential thermal expansion. The cylindrical jacket is mounted sealingly onto the ring.
