  • Patent number: 7871256
    Abstract: A cable guide system and method are disclosed for a mold forming and extruding machine. The machine has a pair of spaced apart vertical members. The cable guide system includes a support shaft secured to the pair of vertical members. The support shaft retains a first stop member, a tensioning device, a spool loaded with a flexible reinforcement cable, and a second stop member. The spool cooperates with the tensioning device to prevent the cable from prematurely unraveling. The cable guide system further includes a guide member located below and forward of the spool and in horizontal alignment with a plunger. The guide member is capable of changing the direction of the flexible reinforcement cable as it is unwound from the spool. The plunger is capable of extruding a moldable substance from the machine while allowing the flexible reinforcement cable to pass through an aperture formed therein.

  • Publication number: 20100316754
    Abstract: Die tooling is formed by forming a series of passages extending in the length of the tooling where each passage has a circumference defined within a body member of the tooling. Preferably the passages are primarily formed using a drilling procedure. The passages define a predetermined pattern of outlets adjacent the extrusion outlet or outlets. The passages between the inlets and outlets can be formed in a series of connected body members with each passage extending through each body member. Die tooling of this design is more robust and cost effective to manufacture.

  • Publication number: 20100301513
    Abstract: An apparatus for extrusion forming a sheet product having an extruder assembly with a sheet die through which a flowable material is delivered and a roll stand assembly made up of a roll stack sub-assembly and a sheet take-off sub-assembly. The roll stack assembly has first and second rolls between which a nip location is defined at which flowable material from the sheet die is delivered. The sheet take-off sub-assembly produces an advancing force upon a first sheet component made up of at least the first sheet layer. The roll stand assembly further has a coating system for applying a coating component to a surface on at least one sheet component advancing through the apparatus. The roll stand assembly is constructed to be reconfigured thereby to change a path traveled by the at least one sheet component and facilitate selective application of the coating component.

  • Publication number: 20100237535
    Abstract: A method and apparatus for pretreatment of slider layer for extruded handrails has a slider layer source, a means of conveying the slider layer to a heating module which subjects the slider layer to an elevated temperature for a residence time, and a means of conveying the slider layer to an extrusion die head. One or more control feeders may be implemented for maintaining portions of the slider layer in a substantially tension-free loop as the slider layer is conveyed from the slider layer source to the extrusion die head. A cooling zone may be included to ensure adequate cooling between the heating module and the extrusion die head. Means for reducing heat transfer between the extrusion die head and the slider layer is also provided.

  • Publication number: 20100219556
    Abstract: Honeycomb extrudate is made by extruding a plasticized ceramic-forming batch material to form a length of wet honeycomb extrudate, transferring the extrudate to a support tray, and transferring the tray and extrudate to a dryer, the tray being capable of contactingly supporting greater than one-third of the circumferential surface of the wet extrudate. The extrudate is subject to reduced handling damage, e.g. from forces of gravitational and/or lateral acceleration arising during transfer.

  • Publication number: 20100123262
    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.

  • Patent number: 7700023
    Abstract: A method for producing an environment protective foamed thermoplastic resin polymer comprises using an extruder with a helical rod to be driven to rotate. The extruder has a feeding section, a melting section, a mixing section and a heating-shaping section formed therein. The method includes a plurality of steps, in which thermoplastic resin is heated, melted in the melting section and moved into the mixing section, and hollow expansion balls are fed into the extruder to be evenly mixed with the melted thermoplastic resin. Then the hollow expansion balls are slightly heated and inflated, and moved into the heating-shaping section, and then the balls are heated at foaming temperature, foamed and inflated. After being injected through a nozzle, the melted thermoplastic resin and the hollow balls become a foamed thermoplastic resin polymer with a preset thickness and shape.

  • Publication number: 20100055272
    Abstract: The invention provides methods and moulding devices for moulding three-dimensional products from a mass of foodstuff which is suitable for human consumption, in particular from a mass of meat, in particular chicken. The method comprises filling a mould cavity with a portion of the mass under the influence of a filling pressure exerted on the mass and for a filling period via a filling opening associated with the mould cavity, closing the filling opening of the mould cavity and holding the mass in the mould cavity for a fixing period. Then, the mould cavity is opened and the moulded product is removed from the mould cavity. The method uses fixing-pressure-exerting means which are designed to exert a fixing pressure which acts on the mass in the mould cavity after the filled mould cavity has been closed.
