Cables are constructed with extruded discontinuities in the cable jacket that allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of material in the cable jacket.

A filament is fed to an extrusion head. The filament has a semi-crystalline polymeric reinforcement portion and a polymeric matrix portion. The reinforcement and matrix portions run continuously along a length of the filament. The reinforcement portion has a higher melting point and a higher crystallinity than the matrix portion. The temperature of the filament is raised in the extrusion head above the melting point of the matrix portion but below the melting point of the reinforcement portion so that the matrix portion of the filament melts within the extrusion head, thereby forming a partially molten filament within the extrusion head. The partially molten filament is extruded from the extrusion head onto a substrate, the reinforcement portion of the partially molten filament remaining in a semi-crystalline state as it is extruded from the extrusion head. Relative movement is generated between the extrusion head and the substrate as the partially molten filament is extruded onto the substrate in order to form an extruded line on the substrate. The matrix portion of the extruded line solidifies after the extruded line has been formed on the substrate.

A weather strip including a bottom wall, a first lateral wall and a second lateral wall and in which an angle between the bottom wall and the first lateral wall is constant and an angle between the bottom wall and the second lateral wall is partially varied in a longitudinal direction is manufactured. The method includes: a first step of pre-forming the angle of the first lateral wall and the angle of the second lateral wall to be constant and equal to or larger than final maximum angles; a second step of regulating a boundary between the bottom wall and the second lateral wall from moving toward the first lateral wall by a regulating member; a third step of partially varying the angle of the second lateral wall by a movable roller; and a fourth step of forming the angle of the first lateral wall by a fine-movable roller.

Provided is a production apparatus capable of producing a flexible tube whose hardness is naturally varied along the length direction thereof. This mixing valve includes: a first valve configured to distribute a first resin to a resin supply path and a resin discharge path; and a second valve configured to distribute a second resin to the resin supply path and the resin discharge path. In the mixing valve, the mixing proportion between the first resin and the second resin is increased or decreased in association with molding of the flexible tube, by changing a distribution ratio of the first resin in the first valve and a distribution ratio of the second resin in the second valve while keeping constant the total of the supply mounts of the first resin and the second resin supplied to a die.

A fastener assembly includes a molded plastic fastener shaped to define a filament, a paddle at one end of the filament, and a cross-bar at the other end of the filament. The fastener assembly additionally includes a printed label embedded in the paddle, the printed label including an electrically chargeable, stiffness enhancing laminate that is applied to a print receptive polymer substrate. An in-line system for manufacturing a continuously connected supply of the fastener assemblies includes a rotatable mold wheel, a feed mechanism for advancing a continuous, ionized, printed polymer web in a near tangential relationship relative to the mold wheel periphery, a cutting mechanism for transversely cutting through the web to form a plurality of rectangular printed labels that are magnetically drawn into corresponding cavities in the mold wheel, an extruder for applying molten plastic into the cavities and a knife for skiving excess hardened plastic from the mold wheel periphery.

A method for manufacturing an automobile weather strip comprises: (a) weather strip manufacturing step wherein the seam material and a thermoplastic elastomer are extruded and molded; (b) pretreatment step wherein the surface of the weather strip manufactured is pretreated; (c) slip agent applying step wherein a slip agent made by mixing silicone and polyurethane is applied to the surface of the weather strip pretreated through the pretreatment step; and (d) curing step wherein the slip agent coating layer formed through the slip agent applying step is cured.

Disclosed is a ceramic honeycomb structure comprising a honeycomb body and a multilayered outer layer formed of a thick core layer applied and rapidly dried and a thin clad layer dried more gently to form a crack free dual skin layer. The core layer may have properties that are closer to those of the ceramic honeycomb body in service than the clad layer that may provide a tough outer shell to withstand handling and assembly.

This disclosure relates to an article (e.g., a vapor-permeable, substantially water-impermeable multilayer article) that includes a nonwoven substrate and a film supported by the nonwoven substrate. The film includes a polyolefin, a nanoclay, and a pore-forming filler.

This disclosure relates to an article that includes a nonwoven substrate, a first film supported by the nonwoven substrate, and a second film such that the first film is between the nonwoven substrate and the second film. The first film includes a first polymer and a pore-forming filler. The difference between a surface energy of the first film and a surface energy of the nonwoven substrate is at most about 10 mN/m. The second film includes a second polymer capable of absorbing and desorbing moisture and providing a barrier to aqueous fluids.

The present disclosure relates to methods and systems for manufacturing rotational spun materials. The rotational spun materials are medical appliances or other prostheses made of, constructed from, covered or coated with rotational spun materials, such as polytetrafluoroethylene (PTFE).
