  • Patent number: 10065353
    Abstract: An upstream/downstream process for making map pocket stiffeners formed of extruded material and a wire. The extrusion is drawn through a die of a main extruder forming a main body with a channel and the extrudate is then pulled through a first cooling tank to cool the extrudate and set the profile. The wire is automatically indexed into the channel by a programmable indexing device for proper location and distance between each piece of wire. The extrudate with the wire is re-heated and then pulled through a secondary extruder to encapsulate and seal the wire within the extruded material. The extrudate is cooled in a second cooling tank and passes through a series of rollers to achieve a predetermined shape before being cut and profiled to predetermined lengths and dimensions.

  • Patent number: 8734609
    Abstract: A process for continuous manufacturing of moisture-curable polyurethane formulations used as sealants and adhesives. The process is characterized by the fact that the reactive components are introduced independently, and without the need for a prepolymer, to a mixer. Solid or liquid raw materials can be either pre-blended or fed directly to the mixer, a twin-screw extruder, which provides the requisite energy to homogenously mix the raw materials and drive the chemical reaction. The process is designed so that the extruder barrel and screw allow variable feed addition and heat exchange down the length of the machine. This allows various operations to be performed at different points in the extruder, including reaction, dispersive mixing, distributive mixing and devolitization.

    Abstract: An extrusion device includes a sculpted extrusion die comprising a pair of mating die lips having sculpted surfaces and defining a die exit for an extrudate. The contour of the sculpted surfaces is substantially similar to the contour of a juxtaposed surface configured for receiving the extrudate from the die exit of the sculpted extrusion die. The sculpted extrusion die preferably comprises a die lip adjustment mechanism for adjusting a thickness of the extrudate exiting the die exit and the thickness of the extrudate received on the juxtaposed surface. The air gap between the die exit of the sculpted extrusion die and the juxtaposed surface preferably is substantially eliminated by adjusting the distance between the sculpted surfaces and the juxtaposed surface. A method of adjusting a thickness of a substantially continuous sheet of extrudate formed using an embodiment of the sculpted extrusion die of the invention is provided.

  • Patent number: 8287800
    Abstract: A method for making a polymeric web exhibiting a soft and silky tactile impression on at least one side thereof. The method comprises the steps of providing a forming structure being moveable upon a forming drum and comprising a plurality of protrusions extending from the forming structure, the protrusions being generally columnar forms having an average aspect ratio of at least about 1. The forming structure is disposed adjacent a vacuum chamber and vacuum is applied at a sufficient level to induce a sufficient partial pressure to conform a precursor web to the forming structure, thereby forming the polymeric web. The precursor web can be cast directly onto the forming structure, or it can be re-heated by re-heat means to elevate its temperature sufficiently to permit vacuum formation.

  • Patent number: 8285411
    Abstract: Methods for generating supports (30) for parts (50) produced by solid freeform fabrication (“SFF”) are disclosed. The method includes defining a plurality of layers (L) that make up the part, and for each layer, determining those regions (R) that require support. The method also includes merging the regions for the different layers (L) into one or more common regions that require support, and providing at least one support for each of the one or more common regions. The result is that fewer supports are used as compared to conventional SFF fabrication methods.

  • Publication number: 20120247049
    Abstract: A wall panel that can be secured along an associated wall structure is formed from a thin-walled material having a substantially uniform thickness. The wall panel includes first and second longitudinally-extending edges, and first, second and third wall portions. A first interengagement feature extends lengthwise along the first wall portion, and a second interengagement feature extends lengthwise along the second wall portion. The first and second interengagement features are dimensioned to cooperate with one another to operatively provide a non-visual indicator of a positive interengagement between two wall panels. A wall panel kit and a method of manufacture are also included.

  • Publication number: 20120126446
    Abstract: The invention relates to a method for producing a concrete body having a planar upper side, wherein a high surface quality is obtained. In the method, a concrete body is extruded from unset concrete and is provided with a groove profile at the upper side thereof by means of a profiling unit. By means of the profiling unit and depending on the comb-shaped profile thereof, the sand particles are separated according to size, wherein large sand particles are displaced from the surface area of the concrete body toward the inside, this being toward the interior of the concrete body. Only fine sand particles can pass the profile, whereby raised areas of the groove profile are formed, which are made of extremely fine-grained unset concrete. Subsequently, the upper side of the concrete body is leveled by means of a leveling unit, wherein the raised areas of the groove profile are crushed and the fine-grained unset concrete of the raised areas of the groove profile is distributed to form a cover layer.
