摘要： A die member forming a component of cross-head die apparatus is configured to facilitate removal of the die member from the axial bore of the body of the apparatus following assembly of a die member at room temperature with a body at elevated temperature. The external, frustoconical surface of prior art die members is provided with recessed portions which do not contact the opposing surface of the axial bore in the body. Also, the angle of taper of the conical plane of the mating die member and body bore surfaces is increased to 7.degree. from the prior art standard of 5.degree..

摘要： A crosshead die for an extrusion system provides a balanced, even flow of molten material around a circumference. The die has a cylindrical body with opposite first and second ends, an outer wall, a horizontal centerline and a vertical centerline. The die further includes a reduced diameter end portion at the second end thereof. The reduced diameter end portion includes an axial bore. The cylindrical body further has a recessed surface in the first end, and a circular groove in the recessed surface. The groove has an inner edge and an outer edge and the outer edge includes two inwardly curved blending wedges which are positioned in opposed relation on the vertical centerline. The inner edge of the groove merges into a frusto-conical inner wall which tapers axially inwardly and merges with the axial bore in the reduced diameter end portion. The inner edge of the groove has a lesser height than the recessed surface. The cylindrical body further includes a flow inlet on the outer wall which is aligned with the vertical centerline. The body further includes first and second symmetrical flow channels which extend into the body from the flow inlet. The flow channels angle outwardly from the vertical centerline toward the outer wall and then turn forwardly to open outwardly into the groove.

摘要： A composite structure comprising a preformed flexible laminate in adhering contact with at least a first and second transparent or translucent panel members such as would be useful as an insulated glass unit. The flexible laminate contains an undulating spacer element either partially or totally embedded within a core material and has a polymeric coating on at least one surface thereof. The flexible laminate effectively seals the interior of the panel structure from air and/or moisture and maintains a desired distance between the panels. A multi-cavity extrusion die for forming the preformed flexible laminate has a core cavity for receiving the core material as well as the undulating continuous spacer element. Converging walls within the core cavity serve to embed at least one side of the spacer element in the core material and a land area forms a desired shape or configuration wherein the spacer element undulation is maintained. At least one polymeric feed cavity located downstream from said core cavity and said land area applies a polymeric film or coating to at least a surface of the embedded spacer element. A plurality of optional feed cavities can apply the same or different polymers to additional surfaces of the embedded spacer element and can totally cover or encapsulate the same.

摘要： A cross-head die for applying one or more layers of coating materials to a single, longitudinally fed, filamentary member, or to a plurality of such members in spaced, side-by-side relation. Tip and die members of relatively flat, wafer-like configuration are placed in a cylindrical cavity of the body member of the apparatus with central openings in each of the tip and die members coaxially arranged and a protrusion surrounding the opening in the tip extending into the opening in the die. Flowable coating material is injected through a radial opening in the body member and flows in both directions about an annular passageway formed by cooperatively arranged grooves in the peripheries of the tip and die members. The coating material flows from the annular passageway to the die aperture through opposing, spaced, angularly arranged surfaces on the tip and die members. In an embodiment for applying two layers of coating material, two tip members and a single die member, all of wafer-like configuration are employed, and in an embodiment for coating multiple members the apertures in the tip and die are of oblong configuration.

摘要： A method of extruding degradable plastic material in tubular form includes providing an annular extrusion die having an annular extrusion orifice and a longitudinal extending annular passage for conveying plastic material to the extrusion orifice. The die also has at least one arcuate passage extending at least partly around the annular passage such that the annular passage completely surrounds, or where there is more than one arcuate passage in combination completely surround, the annular passage inwardly or outwardly thereof and are in communication therewith. A separate melt stream of degradable plastic material is provided for each arcuate passage and each separate melt stream of degradable plastic material is incorporated with non-degradable plastic material in a circumferentially continuous manner to produce separate encapsulated melt streams. Each encapsulated melt stream is fed to a respective arcuate passage to cause encapsulated plastic material to pass into the annular passage with subsequent extrusion in tubular form from the annular die orifice.

摘要： Multilayer fluid conduits are formed by adhering to a tubular outer surface of a metal pipe, a thermoplastic outer layer. The outer layer permits ends of the multilayer conduit to be joined together in leak-proof fluid conduit systems simply by adhering the conduit ends with compatible thermoplastic fittings. For fire protection systems, the preferred metal is steel, the preferred thermoplastic is CPVC and the preferred adhesive is heat activated. The adhesive coated metal pipe is preheated and the CPVC is extruded onto the outer surface of the heated metal pipe. Through the use of fire resistive CPVC, the multilayer conduit systems of the present invention can be installed in more severe fire threat areas than can existing, all plastic piping, including all CPVC piping systems. The conduit is assembled into systems on site simply by cutting and direct bonding with ordinary, all plastic fittings using appropriate bonding agents such as solvent based adhesives. CPVC fittings are preferred for fire protection systems.

摘要： An extrusion molding apparatus includes a die head with first, second, third and fourth annular nozzles. An adhesive extruder is connected to the first and third nozzles, a barrier extruder is connected to the second nozzle and a reclaimed material extruder is connected to the fourth nozzle. Inner and outer main material flow passages are connected to a main material extruder, as well. The annular nozzles and the main material flow passages are connected to an extrusion nozzle for forming a parison. The barrier material extruder has a cylinder which is connected to the second nozzle. A screw lies within the cylinder. The second nozzle has a ridge opposite an end of the screw, for dividing the extruded barrier flow material, mitigating stagnation of the barrier material as it passes through the second nozzle. A method of forming a parison is described, as well.

Insulation is provided between the first and second dies and the first die is water cooled. A layer of insulation is provided between the spaced portion of the first and second dies. A third die is mounted to the second die and co-extrudes a third material onto the laminate formed by the first and second dies. The third die is connected to the second die but has portions spaced from the second die. The spaced portion between the second and third dies are insulated. A thermosetting polymer, such as FKM, is extruded by the first die at a temperature of about 180.degree.-200.degree. F. A fluorinated, thermoplastic polymer, such as THV, is extruded from the second die at a temperature of about 480.degree. F.
