    Abstract: A spiral distributor for a die head of a foil extrusion line has spiral channels provided with shortening sections in their backward area. As compared to a geometrical rule for a discontinuation of the spiral channels which is valid in a prior section of the spiral channels, this arrangement leads to a faster discontinuation of the spiral channels. The design of the backward area of the spiral channels does not affect the good overlaying effect of the front part of the spiral channels. As compared to the customary embodiment, the channels are thus equipped with a less profiled backward end which leads to a more cost-effective manufacture and to a lesser flow resistance.

    Abstract: The present invention describe a process and an installation for the production of stiff recyclable sandwich-type polymeric panels, preferably polypropylene-based panels, and the panel obtained, comprising three lines, in one of which a polymeric polypropylene-based foamed core is produced by extrusion (line A); the structural skins are produced in a second line (line B), which skins are formed by a polypropylene-based lamina reinforced with wood fiber, on which lamina there is applied an also polypropylene-based surface coating layer reinforced with glass fibers; in the third line the structural skins produced in line B are adhered by heat and pressure to the foamed core produced in line A. The sandwich panel produced has a thickness between 7 and 40 mm, an overall density of 400-700 kg/m3 and an elastic modulus of 5-10 GPa.

  • Publication number: 20130309345
    Abstract: The invention relates to a cutting apparatus for a granulator for cutting plastics-material strands emerging from nozzles into granules. The cutting apparatus includes a knife rotor which is connected to a drive shaft via an articulation component having a drive part and via a driven part carrying the knife rotor. The drive part is inserted into a spherical head in a matching spherical cap in the drive part. The spherical head passes through by at least one direction axle, about which the spherical head is rotatable in the spherical cap in case of an axial offset of the drive part and the driven part. In this case, an end of the directional axle that emerges from the spherical head is mounted in a groove in the spherical cap and extends transversely to the direction of rotation of the spherical cap such that, in the case of an offset of the drive part with respect to the driven part, the end moves in the groove.

  • Publication number: 20130300016
    Abstract: A honeycomb extrusion apparatus includes a die body and a mask defining a peripheral gap. The peripheral gap includes a first extrusion cross section at a first radial location relative to the extrusion axis and a second extrusion cross section at a second radial location relative to the extrusion axis. An overall flow area of the first extrusion cross section is less than an overall flow area of the second extrusion cross section. In further examples, methods include co-extruding a honeycomb body with an integral skin with the overall flow area of the first extrusion cross section being less than the overall flow area of the second extrusion cross section. In further examples, methods include compensating for different skin flow characteristics associated with a particular honeycomb network configuration of discharge slots in a die body.

  • Patent number: 8496460
    Abstract: A method and apparatus is provided for distributing material through a multilayer pipe extrusion die. A first flow passageway, having a first cross-sectional area and extending along a first flow direction, may be connected to a second flow passageway, having a second cross-sectional area substantially the same as the first cross-sectional area of the first flow passageway, to provide a second flow direction different from the first flow direction of the first flow passageway. A conical passageway may extend from the second passageway toward a dispensing outlet. Material may be distributed from the first flow passageway into the second flow passageway. The method and apparatus may generally maintain the same flow properties of the material at a point before and after the connection of the first flow passageway and the second flow passageway. The flow properties of the material may be altered proximate to the outlet.

  • Patent number: 8491295
    Abstract: An extrusion apparatus including a die and a mask are provided such that no slots feed directly into the longitudinal skin forming gap between the mask and the die. In a method of forming a die adapted to improve skin uniformity of extruded cellular ceramic substrates a slotted block of die material is provided including central slots adapted to form a cellular matrix of the substrate and peripheral slots located outwardly of the central slots designed to be covered by a skin former mask and adapted to extrude peripheral batch material. An arcuate skin former is cut corresponding to a target shrinkage so as to intersect the slotted block such that skin flow from tangent slots at 90 degree positions of the die is limited to the peripheral batch material.
