Abstract: APPARATUS FOR PRODUCING A PLASTIC EXTRUDED ARTICLE HAVING A PRECISION CROSS-SECTIONAL PROFILE. THE APPARATUS COMPRISES AN EXTRUDER HAVING A FUSION SECTION, A COOLING SECTION AND A DIE SECTION. THE DIE SECTION IMPARTS TO THE EXTRUSION A PREDETERMINED CROSS-SECTIONAL PROFILE GREATER THAN THAT ULTIMATELY DESIRED. ALSO INCLUDED IS A CAVITY CUTTING TOOL PROVIDED WITH A PLURALITY OF SPACED CUTTING UNITS, POSITIONED ADJACENT THE EXTRUDER SO AS TO EMBRACE THE EXTRUSION IN ITS PATH LEAVING THE EXTRUDER, AND TO CUT DOWN THE OVERSIZED PROFILE TO THE DESIRED PRECISION PROFILE.

Abstract: Shaped elements of accurate dimension are produced from synthetic plastics materials by pressing them through a shaping tool and are finished immediately after solidification by a cutting tool, wherein the cutting forces are kept remote from the forces which occur by the extrusion operation by means of a withdrawal mechanism.

Abstract translation: 尺寸精确的成形元件由合成塑料材料制成，通过成形工具压制成型，并通过切割工具固化后立即完成，其中切割力远离挤压操作通过退出而产生的力 机制。
