The invention relates to an entry station (1) which comprises at least one passageway for parallelepiped packages, located upstream from the preparation station (3), said passageway (6) being defined by means of lateral rails (7, 8) which are separated by a distance substantially corresponding to the length of said packages (2) and comprising a means for varying the width thereof at the pivoting area of said packages (2). The passageway (6) is defined by a rail (7) which is aligned with the pivoting abutment (15), and a rail (8) located opposite, facing the former, said opposite rail (8) including, in the downstream portion thereof, in the pivoting area, a rail section (14) that extends as far as the entrance to the preparation station (3) and said section can be retracted in order to allow the pivoting of the package (2) halted by said abutment (15) at said pivoting area.
