    Abstract: An extruder which can be applied to various types of resin and elastomer without having to replace a die is provided. An extruder of the present inventions has: a barrel to which raw material, that is raw elastomer or raw material resin, is supplied; a screw that is driven to rotate in the barrel in order to process the raw material together with the barrel; and die 5 that is provided at a discharge point of the barrel and that discharges the raw material that has been processed. Die 5 includes first flat plate 11 having at least one first hole 13 and second flat plate 12 having at least one second hole 14, wherein first flat plate 11 and second flat plate 12 are arranged adjacent to each other along longitudinal axis X1 of the barrel, and at least either first flat plate 11 or second flat plate 12 is movable relative to the other flat plate such that an overlapping part of first hole 13 and second hole 14 can be varied.

    Abstract: A honeycomb extrusion apparatus includes first and second vanes with respective first and second face portions. First and second axial widths of a circumferential feed area are respectively defined between the first and second face portions and the outer feed surface of the die body. In further examples, methods include the steps of selectively adjusting the first axial width and the second axial width of the circumferential feed area by respectively adjusting the first and second vane relative to the mask. In further examples, a honeycomb extrusion apparatus includes a plurality of mask segments that each includes an inner peripheral surface portion. Each of the plurality of mask segments are independently adjustable along a respective radial axis.

    Abstract: A method for normalizing the exit velocity of multiple extrudate strands from a multiple die extruder and apparatus for producing the same. The invention describes utilizing a die with individual channels, and installing metering assembly on each individual channel. The metering assembly can then be adjusted to independently increase or decrease the velocity of product through an orifice. By independently adjusting individual velocities of extrudate strands, after successive iterations of adjusting, measuring, and readjusting, a plurality of extrudate stands can be produced having substantially uniform velocity. Further the invention can comprise a single extruder or a co-extruder used to make a co-extruded product wherein uniform velocity becomes more desirable.

    Abstract: A building structure that is a one-piece extruded building that can simultaneously build inner and outer walls, roof, reinforcement and optionally even floors. Said structure is made up as a composite of an inner and outer encapsulating building material that provides structural strength, plus an inner core material composed of a highly expanding closed cell foam material for insulation. The building material is polymer based, but can also be a polymer-concrete, wherein traditional fibers are minimized and substituted for other aggregates. The polymer in the encapsulating material can have the catalyst encapsulated and premixed into a slurry form activated at the injection point by mechanically rupturing the capsule, or can be mixed and added at the injection point with a specially designed metering injectors. All comers and joints allow the encapsulating building material to join between inner/outer walls forming columns and evenly spaced beams or studs made from the same encapsulating building material. This system of construction can reduce the construction time to a matter of hours what would normally take days, weeks, or months according to the structure and is built by pumps while allowing for mass production and sizeable cost reductions.

    Abstract: In an embodiment, the present invention provides an extrusion device for producing a profile from plasticizable material, including at least one extruder head, in which the plasticized material can be supplied to a gap which is delimited by at least one roller and at least one bar that bears against a bearing surface in a predefined position via a fixing element in an operating position of the extrusion device. The fixing element includes a flat pressure-transmitting element which, in the operating position, can be placed against a pressure surface of the bar that is opposite the bearing surface, the pressure-transmitting element including a double-armed lever, which is pivotable about at least one axis, in order to compensate for a possible deviation from the predefined parallel orientation of the pressure-transmitting element with respect to the pressure surface of the bar.
