Abstract:
A method for continuously wrapping products, wherein it comprises the following steps: continuously feeding, at a first defined speed (V1), along a first path (P1) and in a given direction (D1), a succession of products (3) and the corresponding sheets (15) of wrapping material at least partially wrapped around the products (3) to V form an intermediate wrapper (2a) having a first and a second wing (37, 38) that are substantially transversal to the plane in which the first path (P1) lies, project from a surface (30) of the products (3) and are located on opposite sides of the product (3); folding the first wing (37) towards said product (3) surface (30) and folding the second wing (38) away from the surface (30) until it extends from the surface (30) itself in substantially the same plane using a first folding device (43) that cooperates with the first and second wings (37, 38) as the intermediate wrapper (2a) and the product (3) move forward continuously along an intermediate folding portion,(44) of the first path (P1); gumming at least one portion of the second wing (38); folding back the second wing (38) towards the product surface (30) until its gummed portion comes into contact with the first wing (37), using a second folding device (65) that cooperates with the second wing (38) as the intermediate wrapper (2a) and the product (3) move forward continuously along the intermediate folding portion (44).
