    Abstract: A process, and apparatus for making a fasciated yarn from fibers. The process comprises the steps of subjecting the fibers to a draft cutting step, subjecting the draft cut fibers to at least one amendatory draft cutting step and subjecting the resulting fibers to a yarn formation step, wherein the fibers are continuously transferred from the draft cutting step to the yarn formation step without any substantial interruption of fiber movement between the steps. The apparatus consists in a draft cutting zone comprising spaced sets of rolls through which the fibers are conducted for subjecting the fibers to a draft cutting step, means forming a further draft cutting zone downstream of the aforesaid zone for subjecting the draft cut fibers to at least one amendatory draft cutting step, and a yarn forming means downstream of the amendatory draft cutting zone for subjecting the resulting fibers to a yarn formation step. Transfer means is provided between these zones whereby the fibers are continuously transferred from the draft cutting zone to the yarn formation zone without any substantial interruption of fiber movement between the zones.

    Abstract: A uniformly drafted tow for use in the production of a fasciated yarn and a process for making same. The tow is prepared from a tow material selected from the group consisting of undrawn tow and partially drawn tow, drawn under such conditions that the drawing points of all filaments of the tow are substantially disposed in a straight line having a narrow width of not greater than about 3 mm. The process for making such tow includes a step which comprises drawing the tow under such conditions that the drawing points of all the filaments of the tow are substantially disposed in a straight line having a narrow width.

    Abstract: A process and apparatus are provided for manufacturing a fasciated yarn having uniform yarn construction and high strength. The process comprises subjecting fibers to a draft cutting step, at least one amendatory draft cutting step and a yarn formation step wherein the fibers are continuously transferred from the draft cutting step to the yarn formation step without any substantial interruption of fiber movement between the steps. The apparatus comprises a draft cutting zone comprising spaced sets of rolls through which fibers are conducted for subjecting the fibers to a draft cutting step, means forming a further draft cutting zone downstream of the aforesaid zone for subjecting the draft cut fibers to at least one amendatory draft cutting step, and a yarn forming means downstream of the amendatory draft cutting zone for subjecting the resulting fibers to a yarn formation step and transfer means between the zones whereby the fibers are continuously transferred from the draft cutting zone to the yarn formation zone without any substantial interruption of fiber movement between the zones.

    Abstract: PURPOSE:To mass-produce articles of accurate size by molding an optical transmission branch line out of a transparent material, supporting both its end parts on a casing through supporting bodies made of other transparent materials with a low refractive index, and placing the remaining part in air in a noncontact state. CONSTITUTION:The supporting bodies 2 made of the transparent materials which have the lower refractive index than the transparent material of the optical transmission branch line 1 are mounted on both end parts of the optical transmission branch path 1 molded branching off into plural optical transmission lines. Those supporting bodies 2 are molded by fitting tubular moldings onto the end parts of the optical transmission lines 1a and 1b or placing them in molds. The optical transmission branch line 1 is supported at the supporting bodies 2 by being clamped with two split casings 3 and 3 from above and below, and the intermediate part of the optical transmission branch line 1 which is not supported by the supporting body couple 2 is held in air in the noncontact state. The air layer is inevitably lower in refractive index than the transparent material of the optical transmission branch line, so the air layer itself serves as a clad to branch light with small light transmission loss. Consequently, transmission lines of accurate size can be mass-produced.

    Abstract: PURPOSE:To easily connect the end parts of optical fibers by inserting an optical fiber into one end of a heat contractive tube, contracting the tube with heat, inserting the other optical fiber from the other end of the tube, and abutting and fixing the end faces of both the optical fibers. CONSTITUTION:When only the optical fiber 2 with a large diameter is inserted into one end part of the heat contractive tube 1, adhesive 3 is applied if necessary and the tube with said state is heated, the tube 1 is contracted and the optical fiber 2 is clamped with the tube 1. Simultaneously with said heat compression, the other end side is shaped as a small diameter, but the center of its section almost coincides with the axis of the optical fiber 2. Thereby, the optical fiber 2' with a thin diameter is inserted into the other end of the tube 1 contracted into a small diameter and fixed with the adhesive 5 under the state. Consequently, both the optical fibers are completely connected.
