A die with alignment mechanism includes a die including a through-hole through which a traveling wire travels, a bearing member for rotationally moving the die in a circumferential direction of the traveling wire, and a movable member that moves the die so that a central axis of the through-hole is aligned with a travel direction of the traveling wire without inhibiting the rotational movement of the die produced by the bearing member when the travel direction changes in a direction orthogonal to the travel direction.

This flocking powder coating method comprises: a powder coating attachment step for attaching a powder coating to a base material; a flocking step for attaching, by electrostatic force, a flocking organic filler to the attached powder coating layer; and a fixing step for forming a coating film by curing or hardening a resin included in the powder coating and thereby fixing a portion of the flocking organic filler to the coating film. According to this flocking powder coating method, coating and flocking can be performed without the use of an adhesive.

A light irradiation device includes at least one irradiation unit including a reflective surface which is disposed in a concave inner surface formed to have a substantially arc shape and into which a wire member is inserted, and a light source which is configured to emit light toward the wire member and is disposed so as to face the reflective surface in a direction of an optical axis of the emitted light, and an insertion portion configured to interiorly form an insertion path for inserting the wire member into the reflective surface. The reflective surface is disposed such that a center of the substantially arc shape is eccentric with respect to a center of the insertion path.

A particular method includes using a helical forming tool to make helical grooves on an insulating jacket of a conductive length, such as a wire. A gear may rotate a forming mechanism, such as a protrusion, around the insulating jacket to form the helical grooves. The helical grooves are formed to limit bending of the insulated wire.

A method of applying a coating liquid to an optical fiber is described. An optical fiber is drawn through a guide die into a pressurized coating chamber and through the pressurized coating chamber to a sizing die. The pressurized coating chamber contains a coating liquid. The method includes directing coating liquid in a direction transverse to the processing pathway of the optical fiber in the pressurized coating chamber. The transverse flow of coating liquid counteracts detrimental effects associated with gyres that form in the pressurized coating chamber during the draw process. Benefits of the transverse flow include removal of bubbles, reduction in the temperature of the gyre, improved wetting, homogenization of the properties of the coating liquid in the pressurized coating chamber, and stabilization of the meniscus.

The present invention relates to a cable comprising a conductor surrounded by one or more layers, wherein at least one layer comprises a polymer composition comprising a copolymer of ethylene with one or more comonomers, to a process for producing the cable and to a polymer composition suitable as a cable layer material.

An apparatus and method for modifying an aspect of an exterior polymer material or polymer type material of a linear substrate with a fluid. The apparatus include a variable exposure gap within which the linear substrate is exposed to the fluid. The width of the exposure gap is varied with the speed of the linear substrate traversing the exposure gap to maintain a constant exposure time of the linear substrate with the modifying fluid.

In an insulated wire including a conductor formed into a long shape and an insulation film formed by stacking at least one insulating layer covering a circumference of the conductor, the insulating layer includes a porous region and a resin region. The porous region is formed of a resin and multiple voids, and the resin region is formed of the resin. In the insulating layer, a boundary surface is not provided between a first boundary surface located on a radially inner side and a second boundary surface located on a radially outer side, and the porous region and the resin region are arranged in this order from the first boundary surface toward the second boundary surface.
