    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.
