Apparatus for making an electrode-electrolyte structure includes: a die head defining a substrate pathway for passage of an electrode substrate through the die head from a substrate inlet to a substrate outlet, and an electrolyte pathway for passage of an electrolyte gel through the die head; an electrode feeder for feeding an electrode substrate along the substrate pathway; and an electrolyte feeder for feeding a polymer gel electrolyte along the electrolyte pathway. The electrolyte pathway is arranged to meet the substrate pathway at a junction arranged between the substrate inlet and the substrate outlet, to extrude the electrolyte onto the electrode substrate as it is fed along the substrate pathway.

The present invention is directed to an apparatus for forming a multi-layer web formed from at least two polymeric film tubes in intimate contact with each other but not bonded to each other. The apparatus includes the use of a blown film extrusion die that extrudes two separate blown film polymeric tubes via two separate annular die lips. A fluid cooling system applies cooling fluid across a plurality of surfaces of the two blown film tubes. One of the die lips may be at a different height from the other die lip. The frost line of one blown film tube may be at a different height from the other blown film tube.

Methods and apparatuses for printing a three-dimensional fibrous structure are disclosed. A fibrous layer is printed onto a printing surface by forcing fibers through at least one extrusion die and onto the printing surface. The extrusion die and/or printing surface are moved in the X, Y, and/or Z direction while printing the fibers.

A process of producing a hollow resin-molded article includes: arranging covers on inner walls of mold halves, the covers having shapes corresponding to the inner walls; introducing a pair of sheets of thermoplastic resin each facing the cover arranged on the inner wall of a corresponding mold half; blowing air into a space between the sheets to cause the sheets to respectively contact the covers arranged on the inner walls, and thereby fusion-welding the sheets to the covers; and closing the mold halves; and cooling down the covers and the sheets in a state where the mold halves are closed. In the step of arranging, there are uncovered portions of the inner walls that are not covered by the cover. In the step of closing, there are mold contact portions of the sheets that respectively contact the uncovered portions directly and the mold contact portions are fusion-welded to each other in an overlapping manner.

A three-dimensional netted structure having an upper surface, a lower surface, two side surfaces a left end surface, and a right end surface, including at least a plurality of filaments helically and randomly entangled and thermally bonded together, wherein the filaments are formed out of a thermoplastic resin by extrusion molding followed by cooling with a liquid; and the netted structure is four-surface molded, the upper surface, the lower surface and the two side surfaces being molded. An apparatus and a method for manufacturing the three-dimensional netted structure.

Provided is a lightweight mesh nonwoven fabric having excellent adhesiveness between uniaxially oriented bodies, excellent low-temperature heat sealability, and high strength. A mesh structure 1 includes two or more uniaxially oriented bodies 2, 3; which include a thermoplastic resin layer and a linear low-density polyethylene layer laminated on at least one side of the thermoplastic resin layer; the mesh structure is produced by laminating or weaving the uniaxially oriented bodies through the linear low-density polyethylene layer in such a way that orientation axes L, T of the uniaxially oriented bodies cross; and the mesh structure has properties of: (1) a fiber weight per unit area of 5 to 70 g/m.sup.2, (2) a thickness of the linear low-density polyethylene layer of 2 to 10 m, (3) an adhesive force between the uniaxially oriented bodies of 10 to 60 N, and (4) a tensile strength of 20 to 600 N/50mm.

A plurality of trough extruders are supported upon a lift truck traveling in a circular travel path. The plurality of trough extruders continuously form one piece troughs as the lift truck travels its circular path. A lift mechanism progressively raises the extruders as the lift truck travels its circular path two form continuous one-piece helical water troughs for use in an agricultural growing structure.

A weighing apparatus for the preparation of a mixture of granular components that comprise batches of material required by a plurality of processing machines in a plant for the manufacture of plastic products is described. The apparatus comprises a Multi-Channel Gravimetric Batch Blender (MCGBB) configured to weigh predetermined weights of the raw materials and to combine the weighed portions of raw materials into batches according to a predetermined recipe for each processing machine and a computer that controls the operation of all components of the MCGBB. The MCGBB comprises several weighing units arranged in a way that allows material weighed in each of the weighing units to fall through individual chutes via a common funnel into a manifold that distributes the weighed batches to several processing machines via a system of delivery pipes.

A device and method manufacture an object for a user by fused deposition. A screw conveyor conveys a plurality of solid thermoplastic pellets from a hopper to a barrel. A heating element, coupled to the barrel, melts the solid thermoplastic pellets within the barrel, thereby producing a thermoplastic liquid. The thermoplastic liquid is extruded through a nozzle that caps one end of the barrel, the extruded thermoplastic liquid thereafter solidifying into the object. A computerized control system controls both a flow rate of the thermoplastic liquid, by adjusting rotation of a motor coupled to the screw conveyor, and a position of the nozzle above the build surface according to a three-dimensional shape of the object. The device and method are particularly suited for mass production of customized shoes and other objects, whereby thermoplastic material can be easily combined with customized colorants and blowing agents.
