In an apparatus for making two-component fibers, a polymer which is supplied laterally with respect to a further polymer and a die, is at first distributed inside cross-channels provided in a pre-die, and then being redirected, through holes in the extruding direction. The channels operate to rearrange the polymeric mass with the new distribution above the die, so as to eliminate possible discontinuities of the values of the chemical-physical parameters of this mass and which are due to the direction variation the mass is subjected to as it is switched from the side channels to the cross channels. Thus, a constant value of the mentioned parameters through the polymer mass being supplied to the extruder is assured.
