摘要： An extrusion head for an extrusion apparatus can include a spider for supporting a central mandrel. A high volume reservoir can be mounted to the spider on a downstream side of the spider. The central mandrel can extend longitudinally into the high volume reservoir. The high volume reservoir can have an axially straight annular conduit with a length L and an outer diameter OD. The annular conduit can have an L to OD ratio of about 1:1. A set of dies can be mounted downstream of the high volume reservoir, whereby the high volume reservoir reduces pressure and promotes homogenization of molten polymer flowing therethrough, before reaching the set of dies.

摘要： The extrusion head including a conduit with a central mandrel extending within the conduit for supporting an inner die portion of a set of dies that has inner and outer die portions. An upstream spider and a downstream spider are included, and each have webs supporting the central mandrel at axially spaced apart positions. The webs of the upstream and downstream spiders can have web portions that are axially offset from each other to promote mixing of polymer flowing through the conduit.
