摘要

The invention relates to a device (10) for aligning preforms (12) in a row and righting same, said device (10) comprising a bowl centrifuge (20) formed by: a horizontal circular platen (24) rotating about a vertical axis (B); a fixed peripheral rail (28); at least a first angular sector (20A) for aligning the preforms (12) against the rail (28); and at least a second angular sector (20B) for righting the preforms (12). The device is characterised in that it comprises means for actively ejecting incorrectly aligned preforms (12N) from the row of correctly aligned and righted preforms (12).
