<p>There is described a unit (1) for grouping packages (2) along a transfer path (T), and having an input station (5) receiving groups (3) of packages (2) arranged in longitudinal lines parallel to the transfer path (T); and aligning means (45, 46; 62) which interact with the packages (2) of each group (3) to align them in at least one line crosswise to the transfer path (T). The unit (1) has a rotation device (60) which, following interaction of the aligning means (45, 46; 62)) with the packages (2) in each group (3), is selectively activated to rotate the packages (2) in each group (3) by a predetermined angle about a direction (A) crosswise to the transfer path (T).</p> |
