A device for positioning and orientating an article (2) to be wrapped by means of a machine, comprises a support body (3) rotating around a vertical axis. The device (1) is furthermore equipped with at least one pliers means (5) connected to the support body (3) to rotate together with it and provided with at least two jaws (6, 7) equipped with opening means (8) to hold and to release the article (2). The at least one pliers means (5) is connected to the support body (3) by means of respective rotary means (9) for the rotation, around an axis almost radial in respect to the almost vertical rotating axis of said support body (3), of said at least one pliers means (5) and of the article held thereby. When the article (2), in a predetermined inlet position in front of the at least one pliers means (5), it is positioned between the opened jaws (6, 7) of said pliers means (5), said jaws held said article (2) due to their closure operated by the opening means (8). The support body (3) and the rotary means (9) rotate the at least one pliers means (5) and the article (2) respectively around to a vertical axis and to a radial axis of the support body until the article reaches a predetermined position and a predetermined outlet orientation. When said position and orientation are reached by the article (2), the opening means (8) open the jaws (6, 7) releasing the article correctly positioned for successive workings. |
