Abstract
An apparatus for making packages including groups of products wrapped with stretch film includes a transporting surface for conveying groups of products in a feed direction. A first pair of film feed stations are located on opposite sides of the transporting surface, and a first selection carriage includes at least two units for forming a respective tubular length of film fed by the respective stations. The apparatus also includes means for driving the first carriage to and fro in a direction transverse to the feed direction in such manner as to cyclically perform the following operations: forming the tubular length of film on a first unit outside the transporting surface, and at the same time positioning the other unit with the respective tubular length of film on it in a stretched configuration at the transporting surface to form a part of the latter so as to enable feeding of the group of products into the tubular length of film and releasing of the tubular length of film over the group of products to form a wrapped package.
