The method for manufacturing an individually sheathed strand comprises: conveying a group of metal wires through a die; upstream of the die, applying a first filler product to at least a first portion of the strand; upstream of the die, applying a second filler product to at least a second portion of the strand distinct from the first portion; and extruding a plastic around the group of metal wires passing through the die, so as to envelop the group of metal wires covered with the first and second filler products in a continuous sheath formed of the extruded plastic. The second filler product has greater adhesion to the group of metal wires than the first filler product.

An in-line method for marking a substrate made of extruded synthetic material, the method including the steps of extruding the synthetic material through an extrusion die to form the substrate, marking the substrate by scrolling the substrate obtained from the extrusion die between two rotatably mounted and temperature-controlled rollers with an upper roller and a lower roller, one of the rollers having an impression forming the negative of a decoration or a texture to be marked on one face of the substrate, this same roller or the other of the rollers including at least one notch allowing to guide the substrate as it passes through the extrusion die and between the two rollers. An installation can include in line the extrusion die and the marking device.

A system and method for treating or processing granular absorbent while the granular absorbent is being transported in a fluid stream that preferably is a stream of air. The system includes a pneumatic conveyor with a conduit that draws pellets exiting an extruder into the conduit drying the pellets as they are transported through the conduit. Material can be introduced that dries, coats or otherwise treats the pellets while the pellets are transported through the conduit. Coating material, e.g., powdered bentonite can coat and also dry pellets during transport. A conduit can have inner pellet treating surface that abrades pellets transported through the conduit producing smaller fines that can be packaged with pellets forming a granular absorbent product that forms clumps on top that extend generally horizontally.

A system according to various embodiments can include a source for supplying a material to be treated, an extruder, at least two screws, and a drive coupled to the screws for axially rotating the screws. The extruder includes an inlet for receiving the material, which is fed therein in a controlled manner. The screws are provided within the housing of the extruder. The screws have a plurality of compression and release stages that create mechanical heat which is directly applied to the material to change the mechanical properties of the material thereby facilitating a conversion of a physical state of the material from a non-compactable state to a compactable state as the screws rotate and move the material longitudinally along the screws to produce a final product, for example, a feed tub for use as an animal feed.

The diaphragm for alkaline water electrolysis according to the present invention comprises a porous polymer membrane, the porous polymer membrane comprising a polymer resin and hydrophilic inorganic particles. A porosity of the porous polymer membrane is 30% or more and 60% or less, average pore sizes at both surfaces of the porous polymer membrane is 0.5 μm or more and 2.0 μm or less, and a ratio of a mode particle size of the hydrophilic inorganic particles to the average pore size of the porous polymer membrane (mode particle size/average pore size) is 2.0 or more.

The method for setting an operating point of a film stretching system comprises the method steps: acquiring an input, wherein the input contains: a) a target value for the first production variable; or b) a target value for the second production variable; or c) a target value for the third production variable; specifying: a) a setting value for the second production variable and the third production variable in order to achieve the target value for the first production variable; or b) a setting value for the first production variable and the third production variable in order to achieve the target value for the second production variable); or c) a setting value for the first production variable and the second production variable in order to achieve the target value for the third production variable; controlling the motor arrangement and the extruder arrangement by the control device in such a way that the operating point consisting of the target value and two setting values is reached.

Disclosed are textile fibers, yarns, and fabrics having improved comfort and water and odor adsorption properties, and methods of manufacturing same. The improved textiles have an increased distribution of adsorbing particles distributed at the surface of the fibers and yarns to enable greater overall surface area for adsorbance.

Methods of producing substantially amorphous pharmaceutical formulations by hot melt extrusion (HME) are provided. In some aspects, the methods can be performed at lower temperatures than are typically required for HME. Pharmaceutical formations produced by these methods are also provided.

A thermoplastic polymer advanceable by solid state polymerization is blended with at least one dissimilar thermoplastic polymer. The blend is solid state polymerized to provide a modified polymer alloy blend having at least one physical or chemical property different from that of the blend before solid state polymerization. The modified polymer alloy blend may be coextruded with a layer of thermoplastic extrusion polymer having a melt viscosity similar to that of the modified polymer alloy.

A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.
