Abstract:
An apparatus for wrapping groups of products in film, comprising:a first surface for advancing products along a predetermined conveying direction; a second surface for forming the products received from the first surface into a group of products to be wrapped; a feed unit positioned beneath and in close proximity to a slot separating the first and second surfaces for advancing a film through the slot and cutting the film into sheets of length determined according to dimensions of the group of products being wrapped; and a wrapping means comprising at least one cross rail for carrying and guiding the sheet of film, a single power driven arm disposed on one side of the second surface for rotating about a rotational axis and supporting the at least one cross rail at an end thereof, and adjustment means acting on the single power driven arm for enabling the at least one cross rail to rotate through the slot and describe a first active trajectory above the second surface and a second return trajectory below the second surface, wherein the distances of the first and second trajectories are variably selectable according to the dimensions of the group of products.
