Bottle alignment apparatus

Method for the alignment of a plurality of hollow bodies having four side walls, in particular bottles whose body is in the shape of a parallelepiped, said hollow bodies being furthermore oriented in such a manner that:

• said hollow bodies are provided with respective axes (X) centred on the respective mouth portion and parallel to the walls of the respective parallelepipeds, and
• the respective walls are inclined at either acute or obtuse angles with respect to the plane (P) passing through said axes (X), characterized in that it comprises following phases:
• a) insertion of said plurality of said hollow bodies in a plurality of respective cylindrical cups provided with respective apertures and arranged between two comb-like members that are opposing each other with respect to said cups,
• b) mutual displacement of said comb-like members relative to each other so that appropriate portions thereof are capable of penetrating into respective ones of said apertures and engaging said hollow bodies so as to orientate them in a synchronous manner.
