Abstract
A method for wrapping groups of products with stretch film comprises the following steps: forming groups of products having a front and a longitudinal dimension following a line of feed; winding a stretch film unrolled from a first roll around a plurality of stretching rods positioned inside a film wrapping area and along the product group line of feed; forming a first tubular portion of stretch film; stretching the portion of film by moving the plurality of stretching rods to create an access area, whose transversal dimension is larger than the front, for a single group of products moving along the feed line; releasing the film portion to allow the portion to shrink and thus wrap over the group of products and thus wrapping it; expelling the wrapped package thus obtained onto the feed line.
