摘要： Resin tubes having thick walled portions and thin walled portions are formed by providing a specially configured orifice on an extruder and varying the rate at which the extruded resin tube is pulled from the extruder. The orifice is shaped to form a thin tubular opening and a thick tubular opening communicating with one another, the thick tubular opening being adjacent and down-stream of the thin opening. When the extruded resin tube is pulled at a high speed the thin tubular opening is filled with resin that passes through but does not fill the thick tubular opening. At the slow pulling speed the resin fills at least the open-end portion of the thick tubular opening thereby forming a thick walled portion of the resin tube.

摘要： A process and apparatus for programming the wall thickness of thermoplastic parison extrusions for subsequent conversion to blow-molded plastic articles. The apparatus for forming the parison includes a mandrel or core pin and a die assembly wherein the mandrel is made from a material having predictable and repeatable elastic properties and has enclosed therein a piston and piston rod. The piston rod extends the full length of the mandrel and is connected to the piston on the rod''s opposite end. The piston is contained in a chamber that is connected to a hydraulic fluid source. The wall thickness of the formed parison is changed by varying the size of the extrusion orifice through expansion or contraction of the mandrel produced by the application of release of hydraulic pressure on the top of the piston. The die assembly is particularly suited for extrusion of parisons from heat sensitive thermoplastic material such as polyvinyl chloride since no sliding surfaces are utilized which are known to trap and cause degradation of heat sensitive thermal plastics.
摘要翻译：用于编程热塑性型坯挤出件的壁厚以用于随后转化成吹塑塑料制品的方法和装置。用于形成型坯的装置包括心轴或芯销和模具组件，其中心轴由具有可预测和可重复的弹性性质的材料制成并且封闭有活塞和活塞杆。活塞杆延伸心轴的整个长度，并连接到杆的相对端上的活塞。活塞被容纳在连接到液压流体源的腔室中。通过通过在活塞的顶部施加液压的释放产生的心轴的膨胀或收缩来改变挤出孔的尺寸来改变成型型坯的壁厚。模具组件特别适合于从诸如聚氯乙烯的热敏热塑性材料挤出型坯，因为没有使用滑动表面来捕获和引起热敏热塑性塑料的退化。

摘要： Torque equalizing mechanism for uniformly actuating the die cores of a double parison extrusion head on a vertical ''''wheeltype'''' blow-molding machine and uniformly varying the wall thickness of a pair of parisons simultaneously extruded from the head. A single programming means governs operation of the actuating mechanism. Die cores, extending upwardly from the double extrusion head, are engaged by rocker arms fixed on a rotatably mounted tubular shaft section of a composite shaft having a driver rod fixed internally thereof at a localized central attachment area equidistant from the die core centers. The rod extends from one end of the tube and a crank arm on the outer end of the rod is pivotally linked to a control shaft movable in response to the single programming means. The composite tubular shaft arrangement applies motion to the die cores equally and requires a minimum of head space from a double parison die head, thus facilitating the conversion of existing single parison machine designs to double the output thereof.

摘要： AN APPARATUS AND METHOD FOR PRODUCING NOVEL COMPOSITE EXTRUSIONS ARE PROVIDED AS ARE THE EXTRUSIONS PRODUCED THEREBY. THE APPARATUS INCLUDES MEANS FOR FEEDING AN ELONGATED MEMBER SUCH AS A METAL WIRE, WIRE ROPE, ELECTRICAL CABLE OR OTHER DEVICE THROUGH THE THROAT OF AN EXTRUSION DIE AND EXTRUDING IN SITU THEREON AN EXTRUSION MATERIAL SUCH AS A RIGID OR FLEXIBLE POLYMER. MEANS ARE PROVIDED FOR VARIABLY OPERATING ONE OR MORE TOOLS TO VARY THE OPENING IN THE EXTRUSION DIE SO AS TO VARY THE CROSS SECTION OF EXTRUSION MATERIAL FORMED IN SITU ON THE ELONGATED MEMBER FED THROUGH THE DIE. IN ONE FORM, ELECTRICALLY INSULATING MATERIAL IS EXTRUDED IN SITU ON AN ELECTRICAL CONDUCTOR SUCH AS A WIRE, STRIP OF METAL OR SERIES OF THESE ELEMENTS TO FORM A PROTECTIVE INSULATING SHEATHING THEREIN AND TOOLING IS PROVIDED TO VARY THE THICKNESS OF THE EXTRUSION MATERIAL ALONG PREDETERMINED PORTIONS OF THE LENGTH OF THE COMPOSITE ARTICLE. FOR EXAMPLE, THE TOOLING MAY BE OPERATIVE TO EITHER COMPLETELY STOP THE FLOW OF INSULATING MATERIAL OR SUBSTANTIALLY REDUCE SAME ALONG PREDETERMINED PORTIONS OF THE LENGTH OF THE ELONGATED MEMBER TO EITHER BARE SAID SECTIONS OF INSULATING MATERIAL OR PROVE SUCH LITTLE INSULATING MATERIAL THEREON THAT THE POST-OPERATIVE REQUIREMENTS FOR STRIPPING INSULATING MATERIAL IN ORDER TO CONNECT THE ENDS OF THE

ELECTRICAL CONDUCTOR TO TERMINALS OR FURTHER CONDUCTING ELEMENTS, WILL BE ELIMINATED, IF NOT GREATLY SIMPLIFIED. A FURTHER ADVANTAGE TO BE DERIVED IS THAT THE USUAL WASTE ENCOUNTERED IN STRIPPING OR BARING THE ENDS OF WIRES AND CABLES WILL BE ELIMINATED, IF NOT SUBSTANTIALLY ELIMINATED. IN ANOTHER FORM OF THE INVENTION, AN ELONGATED MEMBER SUCH AS A FINITE SECTION OF WIRE, ROD OR TUBE IS PASSED THROUGH AN EXTRUSION DIE AND PREDETERMINATELY COATED ON ITS OUTSIDE SURFACE WITH EXTRUSION MATERIAL BY AUTOMATERIALLY CONTROLLING THE FLOW OF SAID EXTRUSION MATERIAL TO OCCUR ONLY WHEN THE ELONGATED MEMBER IS PASSING THROUGH THE DIE AND TO BE IMMEDIATELY TERMINATED UPON REMOVING THE ELONGATED MEMBER FROM THE DIE.
