one component of the mixture is deposited on the fibers an important feature of the process of the invention resides in that the carrier is deflected by at least 5 u00b0 and at most 90 u00b0 from its direction preferably as explained below in a range of 10 u00b0 80 u00b0 the degree of deflection of the carrier is chosen mainly in consideration of the nature of the polymer and of the desired quality where mainly linear polymers are used a larger angle of deflection is preferred than with branched polymers optimum results are to be expected if in the processing of polyolefins other than low density polyethlene the angles of deflection lie between 30 u00b0 and 80 u00b0 whereas in the processing of low density polyethylene they should lie in a range between 10 u00b0 and 60 u00b0 in the processing of saturated linear polyesters the selected angles lie in the range from 50 u00b0 to 80 u00b0 and in the processing of cellulose acetate cellulose acetate butyrate the selected range is between 20 u00b0 and 60 u00b0 polyblends can be processed with good results if the angle of deflection is at least 80 u00b0 if longer fibers are to be produced from the polymers listed hereinabove angles of deflection near the upper limits stated are preferred it has been found desirable to protect unfibrillated polymer i e the coating or polymeric film on the drawing surface from the action of the atmosphere.
