    Abstract: The machine for the wrapping of articles in stretchable film of soft plastic material comprises a platform presenting a horizontal flat surface, onto which the article to be wrapped is positioned. The said platform is moved along a quadrangular path, effecting sequentially a lower horizontal run, during which it becomes loaded with the article, a upwardly directed vertical run, which brings the article in contact with the wrapping film and during which the proper wrapping cycle is started, a horizontal upper run, during which the wrapping operation is completed and the article is transferred away from the platform, and a downwardly directed vertical run, which brings again the platform to its loading position.
