A method is provided for making a fiber wire having a fiber bundle core and a polymer jacket. The method includes rotating a spool of fiber bundle about a first rotational axis to progressively unwind the fiber bundle from the spool. The fiber bundle includes a plurality of continuous synthetic fiber filaments. While the spool is rotated about the first rotational axis, the spool is simultaneously rotated about a second rotational axis to thereby twist the unwound fiber bundle about its longitudinal axis. The method further includes coating the twisted fiber bundle with a molten polymer, and permitting the molten polymer to cool to define a flexible outer jacket that encapsulates the twisted fiber bundle.

Present invention is related to an extrusion equipment for processing a fibre composite. The extrusion equipment comprises a decompression and a melt tank arranged and operated vertically along with the direction of gravity. The melt tank comprises a melt tank impregnation section and a melt tank control section with a melt tank cavity as a channel condition defined within. The channel has its inner diameter or passage gradually decreased from top to bottom. The extrusion equipment provided by the present invention is configured in the direction of gravity for processing the melted thermoplastic resin and the fibre vertically for avoiding fibre fracture or breakage and improving the quality of the final products. As the melted plastic is processed vertically along with the gravity, the melted plastic could transfer or pass through the channel quickly without resulting decomposition due to the high heat and the long retention time in the cavity.

A dielectric isolator for a twisted pair cable includes a body formed as an elongate strip with a top surface, bottom surface, a first side edge and a second side edge. A first slot is formed in the first side edge and extends at least half way toward the center of the isolator. A second slot is formed in the second side edge and extends at least half way toward the center of the isolator. During cable manufacturing, first and second wedges open the first and second slots. First and second twisted pairs are inserted into the first and second opened slots, respectively. Third and fourth twisted pairs reside at the top and bottom surface, respectively. The isolator has the cost and reel storage savings of a flat separator tape, while simultaneously providing the internal crosstalk performance of the isolator.

Method for transporting pellets of a glass fibre reinforced thermoplastic polymer composition from a loading position to an unloading position, said pellets comprising a core and a thermoplastic polymer sheath surrounding said core, wherein the core comprises glass fibres extending in a longitudinal direction of the pellets and an impregnating agent, the method comprising loading pellets onto a non-vibrating belt conveyor at said loading position, conveying the pellets by means of said non-vibrating belt convey—or to said unloading position and unloading the pellets from said non-vibrating belt conveyor at said unloading position. Further methods are claimed as regards a process for manufacturing pellets of a glass fibre reinforced thermoplastic polymer composition and a process for the manufacture at a moulding position of a moulded product from pellets of a glass fibre reinforced thermoplastic polymer composition.

An optical fiber drop cable including a cable jacket having an outer surface defining the outermost surface of the optical fiber drop cable. The optical fiber drop cable also includes a subunit, a first strength element, and a second strength element. The first strength element, the second strength element, and the subunit are embedded in the cable jacket, and the first strength element, the second strength element, and the subunit are arranged substantially parallel to each other on a first plane. The subunit includes a buffer tube having an inner surface and an outer surface, at least one optical fiber, and a plurality of strengthening yarns. The plurality of strengthening yarns are disposed between the inner surface of the buffer tube and the at least one optical fiber, and the outer surface of the buffer tube is at least partially in contact with the cable jacket.

The invention is directed to a crosshead die for the extrusion of a profile, such as a uniform ply coat for a tire. The crosshead die is used with an extruder, and includes a body. An inlet is formed in the body, and is in fluid communication with the extruder. An outlet and a flow channel are also formed in the body. The flow channel extends between the inlet and the outlet, and is bounded by an upper wall, a lower wall, a first side wall, and a second side wall. The flow channel is formed with a bend and a cross section that includes a trapezoidal shape to align the flow of elastomer with the center of the flow channel.

A process produces an electrical line which extends in the longitudinal direction and the line has a line core and an outer shell. In a continuous shaping process, individual shell portions of the outer shell are formed successively by surrounding the line core with a curable plastic substance. In at least one portion, the outer shell is produced having a cross-sectional geometry which can be varied in the longitudinal direction of the line.
