摘要： An extrusion die for a plastified thermoplastic resin has an outer part, an inner part inside the outer part and defining with it an annular passage, and webs supporting the inner part on the outer part and defining branch passages connecting an inlet passage formed by the parts to the annular passage. A restriction collar downstream of the branch passages is formed with teeth projecting only partly transversely across the annular passage and leaving an annular space clear for resin throughflow.

摘要： An extrusion head 1 for producing sheet material 2, particularly elastomeric material, reinforced internally with relatively close-packed metal or textile cords 3; on which a die adapter 8 houses a "mandrel" 23 aligned with an output die 16 for the extruded sheet material 2 and having an axial slot 31 for feeding the reinforcing cords 3 to the die 16; the aforementioned mandrel 23 having, on its front end facing the die 16, an insert 32 defining, together with the die adapter 8, an upper channel 34 and a lower channel 35 for supplying plastic material; which insert 32 consists of an upper element 40 and a lower element 41, the front ends of which are arranged contacting so as to define a cord output guide member 56, and the rear ends of which are gripped together with the interposition of an intermediate element 47, so as to define two superimposed cord input guide members 61, 62 converging inside the output guide member 56, having a cord density equal to half that of the output guide member 56, and offset by half the space between two adjacent cords in relation to each other.

摘要： Dual parison extrusion head for multi-layer extrusion blow molding in which a die body surrounds two parallel spaced mandrels to form two cylindrical passages from which parisons are extruded. A series of resin supply conduits are provided for directing each resin to both passages. The series of conduits are axially spaced in the extrusion head to direct a plurality of plastic resins to each of the passages to form a multi-layer parison. The resin supply conduits are symmetrical about a vertical plane transversely bisecting the extrusion head between the two passages to produce flow and thermal symmetry in the resin to balance the resin flow to both passages. The resin supply conduits are configured so as to produce the dual parisons with the resin weld line of the multiple resin layers being located on the blow mold parting line. The resin conduits are positioned to minimize the center distance between parisons to reduce the size of the extrusion head. This is accomplished in part by feeding the resin downwardly before the resin flows into the cylindrical passages to form the parisons.

摘要： A method of manufacturing a multi-layer resin material by employing a plurality of kinds of thermoplastic resin. Resins for inner and outer layers are supplied into a feed block of a feed block type T-die coextrusion apparatus where they are laid up another, and are then sent to the T-die side. In this case, a resin which is practically similar to the resin for the outer layer is supplied as an auxiliary resin to both lateral edges of the multi-layer resins within the feed block. Thus, the sheet extruded from the T-die slit has lateral edges which are made of a single resin.

摘要： An extrusion head for forming a two-part laminated sheet from a single tubular-shaped extrudate stream emitted from the outlet of a single extruder. The stream flow into an enclosed chamber which diverges the stream in width and converges it in thickness. This stream is split by a wedge divider insert which extends across the outlet end of the chamber into multiple parallel, horizontal streams. Each stream then passes through a breaker plate or screen to remove any foreign particles present in the extrudate. A converging preform die in combination with a triangular preform insert converges the upper and lower streams into a single stream at a final die producing the unitary two-part laminate, preferably symmetrical about the horizontal plane. The extrudate preferably is an elastomer and the resulting laminated sheet is used as a tire innerliner. The combined two streams reduces the chance of a discontinuity in one stream lining up with a discontinuity in another stream thereby producing a laminate of high integrity.

摘要： A layer of conductive plastic material can be made to exhibit relatively high conductivity with a relatively small amount of electrically conducting particles included in it if the layer is extruded in a lamellate form. Particularly, sublayers having thicknesses of the size of the conducting particles or less being the randomly distributed particles in one sublayer into close proximity with those in adjacent sublayers. Consequently, relatively short conducting paths through the layer are provided. The laminate layer is formed by an extrusion die with a plurality of dividers adapted to divide the extrudate into sublayer prior to recombination for the extrusion of the final layer. The laminate layer can be coextruded with electrically insulating layers to fabricate electrical components such as capacitors.

摘要： An extrusion die for two-ply seamless plastic tubing, includes an extrusion head with a first nozzle provided with a first centering means; a first hollow mandrel placed within said nozzle; an elongate carrier bearing a second mandrel, a second nozzle and a spider in turn supporting a distributor splitting an extrudate. The first nozzle and the distributor define a first annular extrusion orifice for an outer parison of the tubing while the second nozzle and the second mandrel define a second annular extrusion orifice for the inner parison of the tubing. A threaded member longitudinally adjusts said carrier to vary the size of the first extrusion orifice. A coupling means interconnects the carrier and the first mandrel and allows only the axial, without rotation, movement of the carrier. A second centering means mounts the distributor uniformly spaced around the spider.

摘要： A machine has a nozzle formed with an annular passage centered on an axis and having at an outer axial end an annular mouth. A plastic mass is introduced under pressure into the inner axial end of the passage at two diametrally opposite locations and mixes and passes outwardly along the passage to emerge from the mouth as a tube. The axial outward flow of the mass along the passage is impeded upstream of the mouth to pressurize the mass with a pressure substantially greater than atmospheric. Such flow is impeded either by restricting the passage or by allowing the volume of the passage to increase against a predetermined counterforce. The mass will form when it leaves the nozzle a tube of almost perfectly uniform wall thickness.

摘要： An extrusion head for producing hollow profiles such as thick-wall large diameter PVC pipe has its flow channel divided by a hollow mandrel into two coaxial portions of a flow cross section greater than that of the common portion of the flow channel downstream of these coaxial portions and running through the mouth of the head. According to the invention, the flow channel progressively diminishes the flow section over the length thereof at least from the plate at which the coaxial portions start to eliminate structural defects caused by failure of the streams of synthetic resin to adequately merge.
