METHOD AND APPARATUS FOR PRODUCING A BRAIDED PUFF EXTRUDATE

摘要

A process and apparatus for the production of a braid shaped puffed extrudat e. A tube (30) or other peripheral containment vessel is placed at the exit end of an extruder die (12) that produces two or more extrudate streams. A circular air stream is then introduced into the peripheral containment vesse l downstream of the glass transition point, thereby causing the extrudate streams to braid together within the containment vessel.
