1. A method for manufacturing spherical particles out of plastic, in particular a prepolymer- or polymer melt of a polycondensate, e.g., PET, PBT, PEN, PA or PC, wherein the melt is dripped into droplets by means of an dripping nozzle with numerous melt outlet holes, and the droplets are solidified into particles after falling at least part of a drop distance, characterized in that, at the end of the drop distance, the particles make their way into a receiving area in which at least some of the particles are swirled in such a way as to generate turbulences to move the particles toward the middle of the area and/or area outlet hole.
