RAPID CHANGE DIE ASSEMBLY |
摘要 |
<p>An extrusion assembly comprises a feed member (18) rotatable about its own axis in a feed member passage bore (20) in a die subassembly (12). The die subassembly (12) has two opposing die passages (22,23) leading to alternative die openings. Extrusion material from extruder (A) passes through the feed member (18) to a feed opening which can open into either one of the two die passages (22,23) according to the selected orientation of the feed member (18). In other embodiments, a similarly movable feed passage defining member enables selection of extrusion material from one of plural extruders, to go to a specified die passage. The possibility for rapidly changing extrudate path can increase output e.g. when cleaning of the die passages or changing of die plates (29) is needed. <IMAGE></p> |
