ENTFERNBARER STRÖMUNGSVERTEILER FÜR EINE EXTRUSIONSDÜSE

摘要

An extruder head (10,110) for use in forming at least one strip of polymeric material includes a flow channel (14,114) having a flow inlet end (16,116) and a flow outlet end (18,118). A flow diverter (40,42,140,142) is removably secured within the flow channel of the extruder head. The flow diverter is held securely in place within the flow channel by a fastening mechanism (46,146), and the flow diverter can be easily removed from the flow channel for reshaping or reprofiling as may be necessary to achieve a desired velocity profile of polymeric material flow at the flow outlet end of the flow channel.
