  • Publication number: 20140133813
    Abstract: A manufacturing line includes an extruder and a dynamic caterpuller system located after the extruder along the manufacturing line. During manufacturing, a fiber optic assembly is produced, where the fiber optic assembly includes a tube containing at least on optical fiber. The tube is extruded via the extruder and loaded via the dynamic caterpuller, which includes a closed pipe through which passes a liquid and the fiber optic assembly. The flow rate of the liquid is different than the speed of the fiber optic assembly through the pipe such that drag is imparted on the fiber optic assembly by the liquid.

  • Publication number: 20140087047
    Abstract: A product-spreading hood assembly (10) for use with a die unit (128) includes a deflector (14) having wall structure defining a product inlet opening (90) and a product outlet opening (92); the deflector (14) is preferably generally frustoconical in shape and is supported by a housing (12). An optional air delivery assembly (16) allows air currents to be directed from the area of the inlet (90) towards outlet (92) to facilitate separation of discrete products. Advantageously, the air currents are delivered in a circumferential fashion about the die unit (128). Use of the hood assembly (10) serves to separate high moisture or “sticky” extrudates, thereby preventing agglomeration thereof.

  • Patent number: 8672660
    Abstract: A plate suitable for positioning with an extruder apparatus is provided in which the plate includes at least one temperature sensor. The plate is upstream of the die located at or near the end of the extruder apparatus. The sensor(s) allow for the simultaneous measurement of batch material temperatures at multiple spatial locations across the face of the plate. The temperature sensors associated with the plate can be used to identify spatial and temporal temperature patterns within the batch flow.

  • Patent number: 8668486
    Abstract: An extruder die designed to produce a spiral corn-based snack food product with consistent, tight spiral pitch and the resultant food product. The extruder die has a center post parallel to the flow path along with three cone-shaped receiving ports arranged in a cloverleaf pattern around the center post. The die has three curved slots on the output side of the die which are in fluid communication with the cone-shaped receiving ports. At the distal end of each of these slots is a semi-circular tip. The tip has a diameter larger than the width of its associated slot. Further, the tip is located at the apex of a cone-shaped receiving port with which it is in fluid communication, thus providing for the highest flow velocity of the extrudate through the tip. The resultant flow profile produces the consistent spiral shape of the snack product produced by the die design described.

  • Patent number: 8641397
    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.

  • Patent number: 8641396
    Abstract: Foil extrusion lines use spiral distributors for producing a melt which is as homogeneous as possible during operation. The spiral distributors are mostly available as cylindrical or conical axial spiral distributors or as radial spiral distributors. The spiral distributors have spiral channels that run in a multiple spiral arrangement so that rather flat horizontal edges are formed precisely in initial sections and vertical edges are formed between the beginning of spiral channels and transition sections of adjacent spiral channels. The melt can easily adhere there. To accelerate the melt in critical areas, the course or the cross-section of the channels or the surface are modified.
