An upstream/downstream process for making map pocket stiffeners formed of extruded material and a wire. The extrusion is drawn through a die of a main extruder forming a main body with a channel and the extrudate is then pulled through a first cooling tank to cool the extrudate and set the profile. The wire is automatically indexed into the channel by a programmable indexing device for proper location and distance between each piece of wire. The extrudate with the wire is re-heated and then pulled through a secondary extruder to encapsulate and seal the wire within the extruded material. The extrudate is cooled in a second cooling tank and passes through a series of rollers to achieve a predetermined shape before being cut and profiled to predetermined lengths and dimensions.

A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.

An assembly and process for forming a two stage extruded pipe having a central inner sleeve and a pair of outer attached lobes. The central sleeve shaped (also termed a grout receiving tube) is produced in an initial extrusion operation, following which it enters a cross head operation where a pair of outer lobes are attached to cross sectional exterior surface locations according to a second stage extrusion operation so as to be integrally formed therewith. Other steps include cooling of the dual stage extruded pipe, as well as sectioning and stacking the pipe. Additional steps include forming elongated slots or apertures into the central sleeve portion of the finished extrusion, such in non-interfering fashion with the individual passageway defining and lobes.

In various embodiments, a device for producing a high density compact livestock feed from a loose granular material according to various embodiment can include a source for supplying a loose granular material to be treated and moving the treated material through a series of successive treatment zones. Rotatable screws are provided within an extruder to compress and transport the treated material a die. The treated material is pressed through the die while a two-dimensional cross-section compression is applied to the treated material. In various embodiments, the high density compact livestock feed is produced having a high protein content, a high fat content, high shipping durability, high quality, and high nutritional value, without the addition of additives.

The manufacturing apparatus of the present invention comprises a die for extruding a resin plate and a first roller and a second roller for molding the resin plate. The manufacturing apparatus further comprises: an inner deckel for dividing the resin plate and pre-forming a thick section; and a main molding section provided on the first roller and/or the second roller for molding a non-uniform thickness section from the thick section.

A solidification- and extrusion-molded article of polyglycolic acid, which is formed of a resin material containing polyglycolic acid, the polyglycolic acid having a melt viscosity of 200 to 2,000 Pa.Math.s, and has a thickness or diameter of greater than 100 mm but not greater than 500 mm. A downhole tool or a component thereof and a ball sealer for petroleum excavation are formed by cutting the solidification- and extrusion-molded article. A method for manufacturing the solidification- and extrusion-molded article of polyglycolic acid and a method for manufacturing a ball sealer for petroleum excavation.

The present disclosure relates to extrusion coating systems, extrusion coated substrates, and processes for making the same. In some aspects, extrusion coating systems as described herein may include an at least partially insulated outlet wall, which may facilitate production of coated substrates exhibiting a very desirable surface texture and appearance. Coated substrates of the present invention may be utilized in a variety of end applications, including, but not limited to, interior and exterior construction materials for homes, buildings, and furniture.

A structural polymeric composite includes a stiffening layer. The composite is made in a continuous extrusion process in which the stiffening layer is pulled through a cross-head die as a polymer is extruded over it. The layer includes a film or textile carrier, a filler of carbon fibers, fiberglass, organic fibers or minerals forming a mat. A binder may be dispersed over the mat and a second carrier applied. The mat is subjected to heat and pressure to soften the carriers and binder so they penetrate into the interstices of the filler and binds mechanically with them and the carriers and binder bind chemically with each other to form the stiffening layer. A polymer is then extruded over the stiffening layer, which may be used flat, provided with holes or punches for composite action with the polymer, formed into a profile, or segmented to provide spaced-apart stiffening layers.

Exemplary pressurization and coating systems, methods, and apparatuses are described herein. In certain embodiments, pressurization systems, methods, and apparatuses are used in conjunction with coating systems, methods, and apparatuses to control pressure about a substrate after a coating material is applied to a surface of the substrate. An exemplary system includes a die tool configured to apply a coating material to a substrate passing through the die tool and a pressurization apparatus attached to the die tool and forming a pressurization chamber. The pressurization apparatus is configured to receive the substrate from the die tool and control pressure about the substrate in the pressurization chamber. In certain embodiments, the die tool forms a coating chamber and is configured to apply the coating material on at least one surface of the substrate in the coating chamber.
