Abstract

A method and an apparatus for the sorting of chips (3). The chips, which have kinetic energy, are separated from each other on the basis of the form or the length of their flight curve which depends on their air resistance. The kinetic energy of the chips is generated by a mechanical ejecting device (6) ejecting the chips or by means of a fan conveyor or by means of the wings of a blowing chipper.
