A method and machine for reading and assigning optical codes to a succession of moving articles, each having at least one respective optical code, and the method including the steps of feeding the succession of articles, by means of a conveyor, through a read area; reading the optical codes within the read area by means of at least one optical reader, and determining, as each optical code is being read, the position in space of the optical code with respect to a given space reference; and assigning each optical code to the corresponding article by matching the position in space of the optical code with the position in space of the corresponding article.

1. A method of reading and assigning optical codes, characterized by comprising the steps of:feeding through a read area a succession of articles, each having at least one respective optical code on at least one surface; reading the optical codes on said articles within said read area by means of at least one optical reader; determining the position in space of each optical code with respect to a given reference system; and assigning each optical code to the corresponding article; wherein, for each optical code, said step of assigning the optical codes comprises the substeps of: determining, after the optical code is read, the displacement, as a function of time, of the optical code and corresponding article within said read area; determining, on the basis of the displacement of the article and corresponding optical code, the position in space of the optical code and corresponding article with respect to said given reference system; and assigning the optical code leaving said read area to the article also leaving the read area.
