<p>A device for changing the separation pitch of the articles in a flow of articles in motion includes at least a plurality of article-carrying elements (12) capable of performing an orbiting movement around a main axis (X10) from the position where the articles are picked up (T) to the position where they are released (G). Each carrier element (12) is associated with drive elements (32 to 50) for selectively varying the speed of the aforementioned orbiting motion in line with at least one of the two positions (pickup and/or release). The device includes a structure (14 to 22) for supporting the carrier elements (12) capable of performing a rotating movement around the aforementioned main axis (X10). The drive elements (32 to 50) include at least one guide element (32) that guides the corresponding carrier element (12) in a movement following an arched trajectory centered around the aforementioned main axis (X10). The drive elements (32 to 50) control the movement of the carrier elements (12), maintaining the distance between the carrier elements (12) and the device's main axis (X10) substantially unchanged. <IMAGE></p> |
