The invention relates to a device for aligning objects in bulk, such as preforms (3) having flanges (3b), including: a disk (2) for driving the preforms (3), said disk being is rotatably movable about the axis thereof; a peripheral guide (6) surrounding a central area (13) of the disk for receiving the preforms to be aligned in bulk, a bottom rim of the guide being arranged above and parallel to the disk at a predetermined distance, such that the guide (6) can correctly guide the preforms sliding over the disc (2) by centrifugal force, allowing a portion (3a) of the preform to pass between the disk and the guide and retaining the corresponding flange (3b); and a rigid stabilisation plate (9) having a perform-guiding surface (30) arranged opposite and on a radially inner side of a corresponding guide surface (33) of the guide (6), the stabilisation plate (9) having at least one stabilisation position in which said guide surfaces are substantially parallel and spaced apart by a distance which is to substantially correspond to the thickness of the flanges (3b). |
