identical in size and composition however strands and yarns of different sizes and compositions may be combined to form the rope 70 the first and second types of fibers are combined to form at least to some of the yarns 74 are different as described above with reference to the fibers 24 and 28 turning now to fig1 of the drawing depicted at 120 therein is an example system 120 for combining the first and second fibers 24 and 28 to form the example yarn 20 the system 120 basically comprises a transfer duct 122 a convergence duct 124 a suction duct 126 and a false twisting device 128 the first fiber 24 is passed between a pair of feed rolls 130 and into the convergence duct 124 the second fiber 28 is initially passed through a pair of back rolls 142 a pair of drafting aprons 144 a pair of drafting rolls 146 and into the transfer duct 122 the example first fibers 24 are continuous fibers that extend substantially the entire length of the example yarn 20 formed by the system 120 the example second fibers 28 are slivers or discontinuous fibers that do not extend the entire length of the example yarn 20 the second fibers 28 become airborne and are drawn into convergence duct 124 by the low pressure region within the suction duct 126 the first fibers 24 converge with each other and the airborne second fibers 28 within the convergence duct 124 the first.
