摘要
The extrusion head of a wide profile extruder is divided into two halves which are hingely mounted on the front end of the barrel of the extruder so as to swing outwardly away from one another and away from the barrel when it is desired to open the extrusion head for cleaning. The two halves of the head are swingable through a sufficient angle to permit removal of the extrusion screw from the front end of the barrel. Hydraulically operated clamps are engageable with wedge surfaces provided on the two halves of the extrusion head so as to exert forces in a direction to force the two halves together and also toward the front end of the barrel thereby providing a tight closure capable of resisting the high forces generated in the extruder during operation. The clamps are hingely mounted on opposite sides of the barrel so that they can be swung out of engagement with the two halves of the extrusion head to permit opening of the head.
